3D Scanning and Printing

group assignment

test the design rules for your 3D printer(s)
In our Fablab, we have various Ultimaker printers. I ran the design rules for the Ultimaker 2+ and the Up Mini 2 from Tiertime.



Workspace 223 mm x 223 mm x 205 mm
Filament 2,85 PLA
Technology FDM

UP Mini


Workspace 120 × 120 × 120 mm
Filament 1,75 ABS
Technology FDM

Material Test

I tested different 3D printing processes and materials available at the Lab to have some exhibition pieces.

individual assignment

design and 3D print an object (small, few cm³, limited by printer time) that could not be made subtractively
What can I do that which cannot be produced subtractively and which would still be for my final. So maybe a movable part. So I will design a ball which hangs in a holder and won't fall out of it. BallAdapter


To get a nice surface and to glue the parts together I put the parts in an acetone steam bath. In the left picture you can see two main blocks of my modular robot system. Left unprocessed print, right the print after the steam bath.
In the right picture you can see my aceton bath which consists of a jelly baby box made of PP which is not dissolved by acetone. I used the acetone from the Klute company. Which I bought from Hornbach. In it I have a cloth with magnets attached which is soaked with acetone. Afterwards I put my object on the lid of the box and put the acetone cloth over it. After about 45 minutes I take the cube out again. Then it holds together and has a nice surface.

individual assignment

3D scan an object (and optionally print it)

I borrowed glasses from a friend and experimented with the various scanners in the laboratory which are able to scan them. The ISense in combination with an Ipad mini did not produce any useful results.

EinScan Software


With the software of einscann one can make all adjustments for scanning and edit the scan.


The EinScan Pro from Shining produced better results.

Small Addition

This week is a robot competition in Hannover, where the team I supervise participates in the Robot Cup. Therefore I am not in the Fablab.
