What is Digital Fabrication?
Digital fabrication refers to the process of using computer-controlled tools to create physical objects from digital designs. This technology bridges the gap between virtual designs and tangible products, enabling designers, engineers, and makers to rapidly prototype and produce custom items.
At DesignEDU, we focus on three primary digital fabrication technologies: 3D printing, laser cutting, and CNC machining. Each offers unique capabilities for different applications.
3D Printing
3D printing, or additive manufacturing, creates objects by depositing material layer by layer. It's ideal for creating complex geometries, prototypes, and custom parts that would be difficult or impossible to manufacture using traditional methods.
Common Materials
- PLA (Polylactic Acid) - biodegradable, easy to print
- ABS (Acrylonitrile Butadiene Styrene) - durable, heat resistant
- PETG - strong, flexible, food-safe options available
- Resin - high detail, smooth surface finish
Laser Cutting
Laser cutting uses a focused beam of light to cut or engrave materials with high precision. It's excellent for creating flat parts, enclosures, signage, and decorative items.
Suitable Materials
- Acrylic - clean cuts, available in many colors
- Wood - plywood, MDF, solid wood
- Paper and cardboard - prototyping, packaging
- Leather and fabric - fashion, accessories
CNC Machining
CNC (Computer Numerical Control) machining removes material from a solid block to create parts. It offers high precision and can work with a wide range of materials including metals.
Applications
- Precision mechanical parts
- Molds and tooling
- Furniture and woodworking
- Circuit boards (PCB milling)
Getting Started
Ready to begin your digital fabrication journey? Here are the steps to get started:
