44 Terms

1
New cards

Digital Fabrication

Computer-controlled production of physical objects or devices from a digital model.

2
New cards

Additive Manufacturing

Fabrication approach that builds objects by successively adding material, e.g., 3D printing.

3
New cards

Subtractive Manufacturing

Fabrication approach that removes material from a workpiece, such as CNC milling or laser cutting.

4
New cards

Formative Manufacturing

Fabrication approach that reshapes material into a mold or form, e.g., vacuum forming, blow molding.

5
New cards

3D Printing

Umbrella term for additive manufacturing technologies that create 3-dimensional objects layer by layer.

6
New cards

Fused Deposition Modeling (FDM)

3D printing technique that extrudes melted thermoplastic filament to form layers.

7
New cards

Stereolithography (SLA)

3D printing technique that cures liquid photopolymer resin using a UV laser to solidify each layer.

8
New cards

PolyJet Printing

Material-jetting process that sprays liquid photopolymers and cures them with UV light, enabling multi-material parts.

9
New cards

Computer Numerical Control (CNC) Milling

Subtractive method where a rotary spindle automatically removes material under computer control.

10
New cards

Laser Cutting

Subtractive process that uses a high-power laser beam to cut or engrave sheet materials.

11
New cards

Water-jet Cutting

Subtractive technique that slices materials with a high-pressure water stream mixed with abrasive particles.

12
New cards

Support Structure

Temporary material printed to sustain overhangs and delicate features during fabrication, later removed.

13
New cards

Orientation Determination

Process-planning step that chooses how a part is placed on the build tray to optimize accuracy, time, and supports.

14
New cards

Slicing

Conversion of a 3D model into successive 2D layers that the printer will fabricate.

15
New cards

Adaptive Slicing

Technique that varies layer thickness based on geometry to balance speed and surface quality.

16
New cards

Path Planning

Algorithmic generation of toolpaths for each layer, affecting build time, strength, and surface finish.

17
New cards

Infill Pattern

Internal lattice or raster used to fill unseen volumes, saving material while retaining strength.

18
New cards

G-code

Vector-based machine language that instructs CNC and many 3D printers on precise movements and actions.

19
New cards

PLA (Polylactic Acid)

Biodegradable, easy-to-print thermoplastic filament widely used in FDM printers.

20
New cards

ABS (Acrylonitrile Butadiene Styrene)

Durable, heat-resistant thermoplastic filament; tougher to print than PLA.

21
New cards

TPU/TPE Flexible Filament

Elastomeric materials for FDM that yield stretchable, rubber-like prints.

22
New cards

Polycarbonate (PC)

Extremely tough, heat-resistant filament suitable for high-strength FDM parts.

23
New cards

Multi-Material FDM

FDM capability that prints with two or more filaments to combine colors or functions (e.g., conductive + insulating).

24
New cards

Layer Resolution (Z Resolution)

Minimum achievable layer thickness; smaller values yield finer detail but longer print times.

25
New cards

Build Volume

Maximum physical space a printer can fabricate, expressed as width × depth × height.

26
New cards

Maker Movement

Community-driven culture promoting DIY fabrication, open hardware, and shared designs.

27
New cards

Fourth Industrial Revolution

Era characterized by cyber-physical systems and digital manufacturing transforming production.

28
New cards

RetroFab

Design tool that combines sensors, actuators, and 3D printing to retrofit existing physical interfaces.

29
New cards

MixFab

Mixed-reality environment that overlays digital designs onto the physical workspace for personal fabrication.

30
New cards

FreeD

Handheld digitally-augmented milling device that assists free-form carving with real-time guidance.

31
New cards

Metamaterial

Engineered internal microstructure that imparts novel mechanical or tactile properties to a 3D print.

32
New cards

Personalization / Customization

Adapting a product’s geometry, function, or aesthetics to individual user needs via digital fabrication.

33
New cards

3D Scanning

Technique that captures the shape of physical objects to create digital models for reproduction or modification.

34
New cards

Online Model Library

Repository such as Thingiverse or Shapeways where users share or purchase printable 3D designs.

35
New cards

Support Contact Area

Surface region where temporary supports touch the print; minimizing it eases post-processing.

36
New cards

Overhang

Portion of a model that extends outward without underlying layers, often requiring support material.

37
New cards

Gusset Support

Triangular support style that braces overhangs by connecting them to lower layers or the build plate.

38
New cards

Build Tray

Printer platform on which the object is fabricated; also called build plate or print bed.

39
New cards

Rapid Prototyping

Fast fabrication of physical models for form-factor or functional testing, typically using 3D printing.

40
New cards

Digital Model

CAD or scanned 3D representation that serves as the blueprint for fabrication.

41
New cards

Build Time

Total duration required for a printer to complete a part, influenced by orientation, layer height, and speed.

42
New cards

Support Volume

Amount of auxiliary material generated to stabilize the print; designers aim to minimize it.

43
New cards

Layer Anisotropy

Mechanical property wherein printed parts are stronger within layers and weaker across them.

44
New cards

Material Jetting

Additive method that deposits droplets of material (usually photopolymers) which solidify to form layers.
