3D scanning and printing

Week 6


For 3D printing I use an "Ultimaker 2 Extended +". The 3D model is drawn in "Autodesk Fusion 360" and exported to STL file format. I use Cura for the g-coding.
For scanning I use a "XYZprinting 3D Scanner", the associated software is called "XYZscan Handy".

3D Printing

For 3D printing I use an Ultimaker 2 Extended +. The filament is 2.85 mm PLA. I use Fusion 360 to draw and create the stl file and I use Cura to create the g-code file.
To test the design rule the 3D printer setup is:

Layer Height: 0.15 mm
Infill density: 20%
Print speed: 60 mm/s
Nozzle size: 0.4 mm

Conclusion Designrule for the 3D Printing

With the chosen printer setup the printed hole diameter can be up to 0.4 mm smaller then designed. This is for hole in the horizontal plane.
For the printed pillars the diameter is 0.1 mm smaller then designed.
I could not measured any difference between the two horizontal axes.
The height of the pillars is max 0.2 mm higher then designed.
My investigation shows that the minimum designed wall thickness that can be printed in 3D (using the applicable 3D printer and the current and setup) is 0.4 mm.
For the designed narrow wall distance it appears that the walls melt together if the designed distance is 0.1 millimeters.
I designed a series of walls varying the thickness and the distance from 0.1 mm to 1 mm using 0.1 mm steps. (See Figure 2.)

Individual Assignment

I draw and printed a tesseract. A Teseract is two cubes inside each other. Wikipedia describe the geometry as the four-dimensional analog of the cube.

3D Scanning

I tried to scan my self and print it out in 3D. You find the result in the figures below.

I have prepared for the photometry, but the result is not ready yet.
