Study Notes
3D Printing
- 3D printing involves 7 steps: design creation, file preparation, slicing, printer setup, printing, post-processing, and quality check.
- Design creation involves creating a 3D model using CAD software or obtaining a pre-made model from online repositories.
- File preparation involves exporting the 3D model file in a format compatible with 3D printing (e.g., STL or OBJ).
- Slicing involves converting the 3D model into layers and generating a G-code file that the printer can interpret.
- Best materials for 3D printing include PLA, ABS, PETG, Nylon, TPU, Resin, Polycarbonate, PVA, and Carbon Fiber Infused Filaments.
Molding
- Molding involves 10 steps: design creation, mold fabrication, material preparation, mold setup, material injection/pouring, cooling, mold opening, part removal, post-processing, and quality inspection.
- Design creation involves creating a detailed design or model of the object to be molded using CAD software.
- Best materials for molding include Polyurethane, Epoxy, Aluminum, Steel, Acrylic, ABS, Polycarbonate, and PLA.
Vacuum Forming
- Vacuum forming involves 10 steps: design creation, mold fabrication, material preparation, heating, forming, cooling, mold removal, trimming, post-processing, and quality inspection.
- Design creation involves creating a detailed design or model of the object to be formed.
- Best materials for vacuum forming include Acrylic, PETG, ABS, Polycarbonate, High-impact polystyrene, PVC, Polyethylene, Polypropylene, Thermoplastic Polyurethane, and High-Density Polyethylene.
CNC
- CNC machining involves 10 steps: design creation, conversion to CNC program, machine setup, toolpath setup, dry run, machining, monitoring, part removal, post-processing, and quality inspection.
- Design creation involves creating a detailed CAD model of the part to be machined.
- Best materials for CNC machining include Aluminum, Steel, Brass, Titanium, Plastics, Copper, Stainless Steel, Carbon Fiber Reinforced Plastics, Tool Steel, and Magnesium.
