Rapid Prototyping:3D Printing
ECE 3400 10/15/18
● Fast production● Can quickly iterate● Produce parts not possible with traditional manufacturing● Easy
Motivation
Subtractive Manufacturing (CNC)
Additive Printing
● PLA (polylactic acid)○ Safer? Made from sugarcane/cornstarch - Smoother○ Easier to use - less risk of warping, better sticking to print bed
● ABS (Acylonitrile Butadiene Styrene)○ Oil based, melts at higher temps - Stronger!○ Needs heated bed to prevent warping
● Others:○ PETG, metals, resins
Materials
Stereolithography printing
Workflow
● CAD● STL file (stereolithography)● Slicer● Gcode● Printer
Cura
Design constraints

Design Constraints
Build Plate Adhesion
Infill & Layer Height
● CAD:○ Autocad, Solidworks, Blender, Sketchup, TinkerCAD, etc.
● Slicers:○ Cura, 3D Slicer
● Designs:○ Thingiverse
