ASSIGNMENT:
- design and 3D print an object (small, few cm) that could not be made subtractively;
- 3D scan an object (and optionally print it).

Assignment:3D Scanning and Printing

3D Print Wasp Delta

3D Systems Sense Scanner

The exercises of the 5th week are the 3D scanning of a subject, and the 3D printing of an object modeled by us.

I tried to scan body parts of one of my mates, but I realized that it was really hard, because the scanner was always loosing the subject image.

So I proceeded by scanning an inanimate object. I chose the arm of a mannequin because the aim of my 3D printing exercise was to create women's accessories.

To scan I used the 3D Systems Sense Scanner.
After scanning, I realized that there were flaws in the scanned model. So, I fixed them with "touch up" tool of Sense software.
- I saved the file (sense-mano.ply), and I opened it with Rhinoceros.

Wasp Delta 40x70, 3D Printer

MACHINE FEATURES:

Cylindrical Print Area: 400mm diametr x 700mm height;
Accurancy: 50 micron;
Nozzle Diameter: 0.35 mm – 0,70 mm – 0,90 mm
Filaments used: 3mm (PLA, ABS, nylon, filaflex, Polistirene, Laywood)
Max Speed: 300 mm/s

Software used: Rhinoceros, Grasshopper, Cura, Photoshop.

The objets chosen were a necklace and a bracelet.

It was the first time I used Grasshopper, and it was a great experience. Having the opportunity to control a 3D model, by using variable parameters with simple functions, gives me a feeling of total control of on my work.

After that, I exported the 3D model in .stl format by Grasshopper and I imported it into Cura in order to create the G-code for the machine. Cura is a software provided by Ultimaker, and it is able to get ready G-code for 3d printing.

Settings:
Print Speed: 120 (mm/s)
Printing Temperature: 185 (C)
Bed Temperature: 60 (C)
Fill Density: 20 (%)
Filament Diameter: 1.75 (mm)
Filament: yellow PLA

We have made a lot of tests because every time the printed object lifted up from the floor.
