5. 3D Scanning and printing¶
- test the design rules for your 3D printer(s)
- Document your work and explain what are the limits of your printer(s) (in a group or individually)
- Document your work to the group work page and reflect on your individual page what you learned
What I did in Week5¶
- Test the 3D Printer : Angle, Overhang, Bridge, Wall-thickness, hole test → In this page
- Design and 3D print an object → individual page
- 3D scan an object, try to prepare it for printing → individual page

Angle test conclusion:
Angles greater than 30 degrees CAN be printed fine.
20 is borderline, and Angles less than 20 degrees CANNOT be printed fine.
→Bending should be limited to 60 digree angle.

Overhang Test Conclusion:
overhang which length is under 0.2mm can be printed fine.
overhang which length is over 0.3mm cannot be printed fine.
Design the object in Fusion 360 and export to Cura
inside dimensions : 20, 25, 30, 35, 40, 45 mm + 45, 50, 55, 60, 65, 70 mm
Printed out and check wether they can be printed expextedly
Bridge Test Conclusion:
~45mm : printed very clearly just as I intended
50~60mm : printed clearly to some extent
65mm~ : printed bad-looking
Upper row (Fence) : Shapes less than 0.4 mm thick are not output. Output is available for sizes larger than 0.5 mm.
Downer row (Grooves) : grooves smaller than 0.3mm cannot be output. thicker than 0.4mm are ok
the shape of circle (upper row) : the hole of second from left (3.1, fx : 0.05) is just-fit
the shape of hexagon (lower row) : the hole of the first from left (3.0) is just-fit
