Glossary: Tools and Materials in Maker Practice

Reading Time: 14 minutes

Maker practice combines craft, design, engineering, repair, electronics, and digital fabrication. A maker may build a wooden shelf, prototype a product from cardboard, program a sensor, repair a household object, or create a custom part with a 3D printer.

These activities use different tools and materials, but they share a common working process. Makers define a problem, develop an idea, build a prototype, test it, identify weaknesses, and improve the design.

Understanding workshop vocabulary makes this process easier. It helps beginners follow instructions, select suitable equipment, communicate with other makers, and avoid damaging materials or tools. The following glossary introduces common terms used across manual and digital maker practice.

Maker Practice

Maker practice refers to practical learning through designing, building, modifying, and repairing objects. It often combines traditional hand skills with digital tools and electronic components.

The maker approach values experimentation. A first version does not need to be perfect. It should provide enough information to reveal whether the idea works and what needs improvement.

Maker practice can take place in a personal workshop, classroom, library, laboratory, community makerspace, or professional design studio.

Prototype

A prototype is an early version of a product, structure, or system created for testing. It may demonstrate shape, dimensions, movement, appearance, or technical function.

A prototype can be simple. Cardboard, paper, foam, tape, and reusable components often provide enough information during the first stage.

Later prototypes may use materials and manufacturing methods closer to those planned for the final product. Makers should define what each prototype is intended to test instead of trying to reproduce every feature at once.

Measurement and Marking Tools

Accurate measurement is essential because small errors can become larger as a project develops. Measuring and marking should usually happen before cutting, drilling, or assembling.

A ruler measures short distances and helps draw straight lines. Metal rulers are useful when cutting because a blade can damage plastic or wooden edges.

A tape measure is flexible and suitable for larger objects, rooms, furniture, and irregular surfaces.

A combination square or try square checks and marks right angles. Some combination squares also measure depth and 45-degree angles.

A caliper measures external dimensions, internal openings, and depth with greater precision than a standard ruler. Digital calipers display the measurement electronically.

A marking gauge creates a line parallel to the edge of a wooden board. A scriber scratches a fine line into metal or plastic when a pencil mark would be unclear.

Term	Main purpose	Typical materials
Ruler	Measuring and drawing straight lines	Paper, cardboard, plastic, and thin wood
Tape measure	Measuring long or irregular dimensions	Furniture, rooms, fabric, and construction materials
Square	Checking and marking angles	Wood, sheet materials, and metal
Caliper	Taking precise internal, external, and depth measurements	Printed parts, fasteners, tubes, and machined components
Marking gauge	Drawing a line parallel to an edge	Wood
Scriber	Creating a permanent fine layout line	Metal and rigid plastic

Cutting Tools

A utility knife uses a replaceable blade for cutting cardboard, paper, foam board, vinyl, and some thin plastics. The material should rest on a cutting mat or sacrificial surface.

A craft knife has a smaller blade and provides greater control for detailed models and fine paper work.

A handsaw cuts wood and some plastic materials. Different tooth patterns are designed for different cutting directions and levels of finish.

A hacksaw uses a narrow replaceable blade and is commonly used for metal rods, tubes, bolts, and plastic sections.

A chisel removes or shapes wood. It should be used with the cutting edge directed away from the body and with the workpiece firmly secured.

Snips cut thin sheet metal. Standard scissors should not be used for metal because the blades may become damaged and the material may create sharp edges.

Drill

A drill rotates a bit to create holes or drive fasteners. Cordless drills are common because they can be used away from electrical outlets.

A drill bit is the removable cutting tool fitted into the drill. Bits are designed for particular materials, including wood, metal, masonry, glass, and plastic.

A pilot hole is a small hole drilled before inserting a screw. It guides the fastener and reduces the risk of splitting wood or cracking plastic.

A countersink creates a tapered recess so that a screw head can sit level with or below the surface.

The chuck is the part of the drill that holds the bit. The bit should be centered and secured before the drill starts.

Screwdriver and Driver Bit

A screwdriver turns screws by hand. Its tip must match the shape and size of the screw head.

Common screw drives include slotted, Phillips, Pozidriv, hex, and Torx. Using the wrong driver can damage the head, making the screw difficult to remove.

A driver bit is fitted into a drill or electric driver. Power tools increase speed but can also strip a screw head or drive a fastener too deeply.

The tool should remain aligned with the screw. Excessive speed is rarely necessary during precise assembly.

Fasteners

A fastener is a component used to join two or more parts. Common fasteners include screws, nails, bolts, nuts, washers, rivets, and staples.

A screw has a threaded body that cuts into or engages with a material. Different screws are designed for wood, metal, drywall, plastic, and other applications.

A bolt usually passes through prepared holes and works with a nut. Unlike many screws, it does not normally cut directly into the main material.

A washer sits below a nut or bolt head. It spreads pressure over a larger area and can protect the surface.

A rivet creates a permanent or semi-permanent joint, often between thin sheets. A pop-rivet tool can install certain rivets from one accessible side.

A threaded insert adds durable internal threads to wood, plastic, or thin metal, allowing a bolt to be removed and reinstalled repeatedly.

Clamps

A clamp holds parts securely during cutting, drilling, gluing, or assembly. It can also apply pressure while adhesive cures.

A bar clamp spans larger workpieces. A C-clamp provides strong pressure over a smaller area. A spring clamp is quick to position but usually applies less force.

Clamping pressure should be sufficient to hold the material without crushing, bending, or marking it. Scrap wood or soft pads can protect delicate surfaces.

Clamps should not replace a safe cutting method. The workpiece and tool path must remain stable and clear.

Vise

A vise is a fixed holding device with two jaws. Turning its handle moves one jaw toward the other and secures the workpiece.

A bench vise can hold metal, wood, plastic, or assembled components. Specialized vises are available for woodworking, electronics, and precision machining.

Soft jaw covers protect finished surfaces and prevent metal vise jaws from damaging softer materials.

Pliers

Pliers grip, bend, compress, or cut small components. Their design determines their intended use.

Combination pliers perform general gripping and cutting. Needle-nose pliers reach small or narrow spaces. Locking pliers clamp onto an object and remain closed until released.

Wire cutters are designed specifically for cutting electrical wire and component leads. They should not be used on hard steel unless rated for it.

Files and Rasps

A file removes small amounts of material and smooths an edge. Files are available in flat, round, half-round, triangular, and other shapes.

A rasp has larger cutting teeth and removes wood or soft material more aggressively.

Files usually cut most effectively during the forward stroke. A handle should be fitted to the file tang because the exposed metal point can cause injury.

After filing, the surface may still require sanding to remove scratches.

Sandpaper and Grit

Sandpaper uses abrasive particles to smooth, shape, or prepare a surface. It can be used by hand, with a sanding block, or with a powered sander.

Grit describes the size of the abrasive particles. Lower grit numbers are coarser and remove material quickly. Higher numbers create a smoother finish.

A common process begins with coarse or medium grit and progresses through finer grades. Skipping too many grades can leave deep scratches visible under paint or finish.

Sanding dust should be controlled with extraction, ventilation, and suitable respiratory protection when necessary.

Adhesive

An adhesive joins materials through a bonded layer. The correct adhesive depends on the materials, surface condition, load, moisture, temperature, and required flexibility.

Wood glue is designed for porous wooden surfaces. It usually needs firm clamping while it cures.

Hot-melt glue is applied with a heated glue gun. It sets quickly and works well for models, temporary fixtures, fabric, and some plastics. It may soften under heat and is not suitable for every structural joint.

Epoxy combines a resin and hardener. It can produce a strong bond and fill small gaps, but the components must be mixed in the correct proportion.

Cyanoacrylate, often called super glue, cures quickly and bonds many small rigid parts. It can become brittle and may damage or cloud certain plastics.

Contact adhesive is applied to both surfaces and allowed to become tacky before they are pressed together. Repositioning is usually difficult once contact occurs.

Cure Time and Set Time

Set time is the period required for an adhesive to hold the parts in position. Cure time is the longer period required for the bond to reach its intended strength.

A joint that feels firm may not yet be ready for loading, sanding, or exposure to water. Makers should follow the manufacturer’s instructions rather than judge only by touch.

Solid Wood

Solid wood is cut directly from natural timber. Its appearance and behavior depend on species, moisture, grain direction, and defects.

Grain describes the direction and pattern of wood fibers. Wood usually cuts and splits differently along the grain than across it.

Wood expands and contracts as environmental moisture changes. Projects should allow for this movement, especially in wide panels and outdoor objects.

Hardwood and softwood are botanical categories rather than simple measurements of physical hardness. Some softwoods are harder than certain hardwoods.

Plywood

Plywood is made from thin layers of wood veneer bonded with alternating grain directions. This structure improves dimensional stability and reduces splitting.

Different grades are intended for furniture, construction, exterior use, marine environments, or visual finishes.

The exposed edge reveals the layers. It can be left visible as a design feature, covered with edge banding, or finished with another material.

MDF

Medium-density fiberboard, or MDF, is made from fine wood fibers combined with resin and pressed into sheets.

It has a smooth and consistent surface, making it useful for painted models, furniture panels, routing, and CNC work.

MDF produces fine dust during cutting and sanding. Suitable extraction and respiratory protection are important.

Standard MDF is vulnerable to moisture and may swell when wet. Moisture-resistant grades are available for certain environments.

Particleboard

Particleboard is made from wood particles bonded under pressure. It is common in low-cost furniture and laminated panels.

It is usually less strong at the edges than plywood and may not hold repeatedly removed screws well.

Special fasteners, edge treatment, and careful drilling can improve results.

Steel

Steel is strong, widely available, and used in frames, brackets, fasteners, tools, rods, and sheet products.

Many steels can rust when exposed to moisture. Paint, oil, galvanizing, or another protective finish may be required.

Steel can be cut, drilled, bent, welded, or bolted. These operations require tools designed for metal and suitable control of sharp edges and hot surfaces.

Aluminum

Aluminum is lighter than steel and forms a natural oxide layer that provides some corrosion resistance.

It is used for enclosures, frames, panels, heat sinks, tubes, and machined components.

Aluminum can be cut and drilled with suitable tools, but it may clog certain abrasives and cutting edges. Thin sheets can bend or distort if poorly supported.

Copper and Brass

Copper conducts electricity and heat effectively. It is widely used in wires, electrical tracks, plumbing, and decorative work.

Brass is an alloy mainly made from copper and zinc. It is used for fittings, hardware, instruments, decorative components, and parts requiring easier machining than some steels.

Both materials change appearance through oxidation. This surface change is called a patina.

Acrylic

Acrylic is a rigid transparent plastic often sold under various commercial names. It is used for signs, display cases, models, light guides, and protective panels.

Acrylic can be laser cut and engraved, but it may crack when drilled incorrectly or placed under stress. It is more brittle than some alternative clear plastics.

Special adhesives can create clear joints by softening and bonding the surfaces.

Polycarbonate

Polycarbonate is a clear plastic with high impact resistance. It is used in protective guards, enclosures, visors, and parts that must withstand greater force.

It is generally tougher than acrylic but may scratch more easily. Not every polycarbonate material is suitable for every laser-cutting process, so equipment rules must be checked.

PVC

Polyvinyl chloride, or PVC, is used in pipes, sheets, cable insulation, and flexible products.

Heating or cutting PVC with unsuitable equipment can release harmful fumes. Makers should confirm material compatibility before using lasers or high-temperature tools.

Cardboard

Cardboard is an accessible material for models, packaging, structural experiments, and early prototypes.

Corrugated cardboard contains a fluted internal layer between flat sheets. Its strength depends on the direction of the flutes.

Cardboard can be cut, scored, folded, glued, laminated, and reinforced. It is particularly useful for testing scale and spatial relationships before working with expensive materials.

Foam Board

Foam board contains a lightweight foam core between paper or plastic surfaces. It is commonly used for architectural models, displays, presentations, and mock-ups.

A sharp knife and several light cutting passes usually create a cleaner edge than one forceful pass.

Some adhesives and paints can dissolve particular foams, so compatibility should be tested on scrap material.

Fabric and Textile

Textile is a general term for woven, knitted, felted, or bonded flexible material.

Woven fabric is made from intersecting threads. Knit fabric is constructed from loops and usually stretches more easily. Felt is produced by compressing fibers rather than weaving them.

Textiles are used in clothing, soft structures, bags, filters, covers, wearable electronics, and flexible prototypes.

Important properties include stretch, weight, thickness, fraying, water resistance, and response to heat.

Needle, Thread, and Seam

A needle carries thread through fabric or another flexible material. Its size and shape should match the material and thread.

A seam is the line where two pieces of fabric are joined. Seam allowance is the material between the stitching line and the cut edge.

A backstitch is a strong hand stitch. A running stitch is simpler and useful for temporary work, gathering, or light construction.

Conductive thread can carry electrical current in wearable projects, although its resistance and durability must be considered.

Breadboard

A breadboard is a reusable platform for building temporary electronic circuits without soldering. Internal metal strips connect groups of holes.

Breadboards are useful for testing sensors, switches, lights, microcontrollers, and basic circuit ideas.

Connections can loosen, so breadboards are less suitable for finished products exposed to movement or vibration.

Microcontroller

A microcontroller is a small programmable computer used to control electronic inputs and outputs.

It can read buttons and sensors, process information, and control lights, motors, displays, or communication modules.

Development boards make microcontrollers easier to program and connect. The board still requires correct voltage, wiring, and code.

Resistor

A resistor limits electrical current or creates a specific voltage relationship in a circuit.

Resistance is measured in ohms. Resistors are commonly used to protect light-emitting diodes, set signal levels, and control timing circuits.

The correct resistance and power rating should be selected for the circuit.

LED

An LED, or light-emitting diode, produces light when current flows in the correct direction.

LEDs have polarity. The positive and negative connections must be identified and wired correctly.

A current-limiting resistor is commonly required. Connecting an LED directly to an unsuitable power source can destroy it.

Sensor

A sensor detects a physical condition and converts it into an electrical signal. Sensors can measure light, temperature, pressure, distance, motion, sound, humidity, or other properties.

The sensor’s range, accuracy, response time, operating voltage, and environmental limits determine whether it is suitable for a project.

Actuator

An actuator converts an electrical signal into physical action. Motors, solenoids, speakers, relays, and heating elements are examples.

Actuators often require more power than a microcontroller can provide directly. A driver circuit, transistor, relay, or separate power supply may be needed.

Soldering Iron

A soldering iron heats metal surfaces and solder to create electrical connections.

Solder is a metal alloy that melts at a lower temperature than the components being joined. It forms a conductive mechanical bond after cooling.

A good solder joint requires clean surfaces, suitable temperature, correct contact time, and controlled use of solder.

Ventilation, eye protection, a stable iron stand, and careful handling of hot tools are essential.

Heat-Shrink Tubing

Heat-shrink tubing is placed over a wire or connection and contracts when heated. It provides electrical insulation and mechanical support.

The tubing must be installed before the final connection closes both ends. A controlled heat source should be used to avoid damaging nearby components.

Multimeter

A multimeter measures electrical properties such as voltage, current, resistance, and continuity.

Continuity mode helps identify broken wires and confirm whether two points are electrically connected.

The probes must be placed correctly, and the selected measurement mode must match the circuit. Current measurement requires a different connection method from voltage measurement.

CAD

Computer-aided design, or CAD, uses software to create precise two-dimensional drawings or three-dimensional models.

CAD files can guide manual construction or digital machines. They may contain dimensions, geometry, assembly relationships, and manufacturing information.

Different machines require different file formats and preparation methods. A visually complete model may still need adjustment before manufacturing.

3D Printer

A 3D printer creates an object layer by layer from a digital model. One common method melts plastic filament and deposits it through a moving nozzle.

The model is processed by slicer software, which converts the geometry into machine instructions.

Important settings include layer height, print speed, temperature, support structures, wall thickness, and infill.

Part orientation affects surface quality, strength, print time, and the need for support.

Filament

Filament is the continuous plastic material used by many desktop 3D printers.

PLA is widely used because it prints at relatively moderate temperatures and is suitable for models and many indoor parts.

PETG can provide greater toughness and moisture resistance. ABS is used for durable parts but may warp and produce fumes, requiring suitable equipment and ventilation.

Flexible filaments create bendable parts but may require slower printing and compatible feed systems.

Infill

Infill is the internal structure of a 3D-printed part. It reduces material use compared with printing the object completely solid.

Infill percentage and pattern affect weight, printing time, stiffness, and material consumption. A higher percentage does not automatically create the best part because walls and orientation may have a greater effect on strength.

Support Material

Support material is temporary printed structure that holds overhanging sections during 3D printing.

Supports must be removed after printing and may leave marks. Good model orientation can reduce the amount required.

Laser Cutter

A laser cutter uses a focused beam to cut or engrave compatible sheet materials.

It can process materials such as approved wood products, acrylic, paper, cardboard, fabric, and certain specialist materials.

Not every material is safe. Some plastics release toxic or corrosive gases. Makers must follow the machine operator’s approved material list.

Power, speed, focus, and the number of passes affect the result. Cutting tests should be performed before processing a complete project.

Kerf

Kerf is the width of material removed by a cutting process. A laser, saw, or other tool does not create a line with zero width.

Kerf matters when parts need to fit together precisely. Designers may adjust digital dimensions so that tabs, slots, and joints remain accurate after cutting.

CNC Machine

A CNC machine follows programmed instructions to move a cutting tool or workpiece.

CNC routers are commonly used for wood, plastic, foam, and some metals. Milling machines can perform more precise work in suitable materials.

The tool path, cutting speed, feed rate, bit selection, material support, and workholding all affect quality and safety.

Tolerance

Tolerance is the acceptable variation from a specified dimension. No manufacturing process produces every part at an absolutely perfect size.

A hole may need clearance around a bolt. A sliding part needs enough space to move, while a press-fit connection requires controlled friction.

Tolerances should reflect the material, machine, purpose, and required accuracy.

Finish

A finish is the final treatment applied to a surface. It may improve appearance, durability, water resistance, chemical resistance, or ease of cleaning.

Common finishes include paint, oil, wax, varnish, lacquer, powder coating, stain, and protective sealers.

The surface must usually be cleaned and prepared before application. Different finishes require specific drying conditions and safety precautions.

Personal Protective Equipment

Personal protective equipment, or PPE, reduces exposure to workshop hazards.

Safety glasses protect the eyes from chips, dust, broken tools, and splashes. A face shield may provide additional coverage but does not always replace safety glasses.

Hearing protection reduces exposure to loud equipment. Respiratory protection may be required for fine dust, fumes, paint, or chemical processes.

Gloves protect against some chemicals, rough materials, and sharp edges. They should not be worn near rotating machinery when they could become caught.

Ventilation and Dust Extraction

Ventilation replaces contaminated air with cleaner air. It is important during soldering, painting, adhesive use, laser cutting, and other processes that create fumes.

Dust extraction captures particles close to the source. It is more effective than allowing dust to spread through the workshop and cleaning it later.

General room ventilation and local extraction serve different functions. Some activities require both.

Workholding

Workholding describes the method used to keep a material or component stable during a process.

Clamps, vises, fixtures, jigs, vacuum tables, and machine-specific systems are common workholding methods.

Holding a small workpiece by hand near a blade, drill bit, or rotating tool is unsafe. A secure setup improves both safety and accuracy.

Jig and Fixture

A jig guides a tool or helps position it repeatedly. A drilling jig, for example, can place several holes in the same location across multiple parts.

A fixture holds a workpiece in a controlled position during production or assembly.

Jigs and fixtures reduce measuring time, improve consistency, and make repeated operations safer.

Scrap Material

Scrap material is leftover material from previous work. It can be useful for testing cuts, finishes, adhesives, drill settings, or machine parameters.

A test on scrap can prevent damage to the final component. However, the test material should match the actual material closely because different grades and thicknesses may behave differently.

Choosing the Right Tool and Material

The best material is not always the strongest or most expensive option. It must fit the function, environment, manufacturing process, budget, and expected lifespan of the project.

A prototype may need inexpensive cardboard rather than finished wood. An outdoor component may require greater resistance to moisture and sunlight. An enclosure for electronics needs enough strength while still allowing access for repair.

Tool selection follows the same principle. A power tool can increase speed, but a hand tool may provide better control for one small part.

Makers should consider whether they have the training, ventilation, workholding, and protective equipment required for the chosen process.

Conclusion

Maker practice uses a broad vocabulary drawn from craft, construction, electronics, design, and digital fabrication. Understanding this language helps makers plan projects, follow instructions, communicate problems, and select suitable methods.

Measurement tools establish accurate dimensions. Cutting, drilling, fastening, clamping, and sanding tools transform and assemble materials. Adhesives and finishes affect the strength, appearance, and durability of completed work.

Wood, metals, plastics, textiles, cardboard, and electronic components each behave differently. Digital systems such as CAD, 3D printers, laser cutters, and CNC machines add new production methods but still require knowledge of material properties and tolerances.

Safety remains part of every definition. A tool is not being used correctly when the workpiece is unstable, the material is incompatible, ventilation is inadequate, or the operator lacks suitable protection.

A glossary provides a starting point rather than complete training. Makers develop real understanding by practicing under safe conditions, testing materials, learning from experienced users, and documenting what works.
