3D Printing

Subtractive: the start of CNC machining 
Additive: overview of 3D printing
History (brief...) 3D Printing Terms Glossary
William Urschel's wall building 3D printer (1940s) David Jones "Daedalus" 3D printer in New Scientist (1974) Charles Hull and the first commercial 3D printer (1984) RepRap self-replicating 3D printer (2008)
Why 3D print?

FFF 3D printing and materials to print with
Benchmark tests Failure Print speed Safety, emissions and ventilation Certification YHT - Printer Limits: Support Structures Available materials (Prusa) Available materials (Simplify 3D) PLA PETG Other materials to look up: PMMA, ABS, HIPS, TPU, PVA, PEI, PEEK metal wood Lifecycle, recycling 3D printer that self-adjusts to the material it's given

Assignments
Lingdong Michelle Julia Valdemar group assignment: • test the design rules for your 3D printer(s) individual assignment: • design, document, and 3D print an object that could not be made subtractively (small, few cm3, limited by printer time) • 3D scan an object (and optionally print it)
