Rapid Prototyping:3D Printing
ECE 3400 10/15/18
![Page 2: 3D Printing Rapid Prototyping - GitHub Pages · Rapid Prototyping: 3D Printing ECE 3400 10/15/18 Fast production Can quickly iterate Produce parts not possible with traditional manufacturing](https://reader035.fdocuments.net/reader035/viewer/2022071007/5fc41a3f62e93d7cd257b74c/html5/thumbnails/2.jpg)
● Fast production● Can quickly iterate● Produce parts not possible with traditional manufacturing● Easy
Motivation

● 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
