6. 3D Scanning and printing¶

Assignments for the week¶

Group assignments¶

Test the design rules for your printer(s)

Individual assignment¶

Design and 3D print an object (small, few cm3, limited by printer time) that could not be made subtractively.
3D scan an object (and optionally print it).

Requirements¶

Described what you learned by testing the 3D printers.
Shown how you designed and made your object and explained why it could not be made subtractively.
Scanned an object.
Outlined problems and how you fixed them.
Included your design files and ‘hero shot’ photos of the scan and the final object.
” Cannot be made subtractively ” means the model has undercuts, overhangs or nested parts.

Drawing¶

Drawing parts from file of week 3 (or open in a new tab)
Draw a slide view of another connection type, “Revolve” it and modify original model.
Fit to the original week 3 drawing.

Why it can not make subtractively¶

When make the topper separately and subtractively,
there are under cuts for all 3-axis.
So if it must done by CNC,
5-axis or manually rotation will be needed.
