Week 5

3D Scanning and Printing

Week 5 - Assignments

• Group assignment

  • Test the design rules for your printer(s)
  • Document your work and explain what are the limits of your printer(s) (in a group or individually)

• Individual assignment:

  • Design and 3D print an object (small, few cm3, limited by printer time) that could not be easily made subtractively
  • 3D scan an object, try to prepare it for printing (and optionally print it)

Testing the printer

Autodesk research scientist Andreas Bastian has developed a test procedure designed to help creators better calibrate their machines and showcase their printers’ capabilities to backers on Kickstarter. He developed a single, consolidated STL file that tests a printer’s dimensional accuracy, resolution, and alignment. For example, poor execution of the “bridging” feature shown below will lead to a saggy and stringy print. A well-calibrated printer will make the horizontal feature with fewer of those issues.

Participating creators can download the file and instructions here on GitHub, print tests, and share the images and videos on their project pages. Backers can also use the file to talk objectively about the quality of machines they receive.

Test file printed

Here is the resault of the Ultimaker 3 test

Bridging is looking good.

Fine feature flow on upper deck is stringing

Overhangs looks good but is rough near the end.

Under the upper deck looks fine.

I also found on Thingiverse a diffrent type of test that i also printed out

3d scanning and printing

In the lab we have a Structure Sensor 3d scanner and a Ipad pro that i used to 3d scan

Structure Sensor

The scan software i used is Skanet

Skanect occipital

Then i used að Ultimaker 3 to print out my scan
