Digital fabrication refers to manufacturing equipment being directly driven by digital data. The data is typically derived from CADs (computer-aided design) that are transferred to CAM (computer-aided manufacturing) software. CAM software generates data that defines a specific manufacturing process like 3D printing or CNC milling. Below is an introduction to digital fabrication techniques and tools used in contemporary design practices.

Digital Fabrication Basics

CAD software is used to create a digital design and. the 3D model is exported as a triangulated mesh. The model describes the product’s geometry and, serves as input for the fabrication tool. Slicer software acts as a bridge between the virtual mesh and the fabricated model. In order to generate toolpaths, software simulation and user input are integrated into machining operations. arts are then manufactured from CAM data with minimal or no human intervention. The fabricated parts may need to undergo a finishing process to achieve their ideal appearance and properties.

3D Printing

Also known as additive manufacturing (AM), 3D printing consists of the following methods:

  • Fused Deposition Modeling (FDM): This is an affordable and, beginner-friendly technique that melts and extrudes thermoplastic filament. The material is then deposited layer by layer in the build area via a print nozzle.
  • Stereolithography (SLA): This 3D printing method uses photopolymerization to cure liquid resin into rigid plastic., It is great for printing functional prototypes with complicated designs.
  • Selective Laser Sintering (SLS): A high-powered laser that fuses polymer powder particles. U nfused powder acts as a support framework so that products maintain excellent mechanical qualities. 

CNC Tools

Subtractive processes begin with solid bars, blocks, or rods formed through boring, grinding, cutting, and drilling. Computer numerical control (CNC) tools include:

  • CNC Machining or CNC Milling: Aa spinning tool and fixed part used to remove unwanted materials. The process is used to create functional prototypes.
  • Laser Cutters: An efficient and cost-effective tool that uses, high-precision lasers. It can cut through or engrave materials to create a variety of prototypes and parts.

CAD

CAD is one of the best ways to convert an idea into a digital design. Solid modeling is traditionally used to create 3D objects and focuses on linear motions. Solids are combined and finished before being digitally manufactured. Surface modeling, can be carried out in the modern solid modeling software like Solidworks and Autodesk Fusion 360.
