3D Scanning and Printing

Group project: test the design rules for your printer(s)

We had tested a Prusa i3 printer and a Hephestos 2 printer
Here are the links for testing the design rules of the printers:
3D test by by tleijssen
Torture Test by MAKE
HS Printer test - ver 3 by energywave
We had tested the following rules:
The possible angle of printing without support
The minimalist wall thickness Possible hight Printing complex structures

It is important to note every complex structures is printable if you adjust the speed of printing, the printing fill and the wall thickness

There is another printing method for printing the most narrow wall thickness that is possible named Spline, for printing vase for example

Design and 3D print an object that could not be made subtractively

Designing the Object

I’ve designed a small scale prototype of a single brick unit for my final project
I’ve made the design in 123D Design as i found there a simple solution for filleting the cube’s edges
I’ve separate the cube into two (top and bottom) parts which can be assembled to one unit

The bottom includes two pairs of wheels, each pair can be rotated on a single axis

The bottom and the wheels were printed at a single operation

After finishing the design i’ve exported two separated STL’s files for the top and the bottom as i was printing them apart
I’ve imported each STL file into Cura and made the file’s Gcode for printing in Hephestos 2 printer

The Printed Object

The parts were placed for printing turning the fillet side up in order to achieve a fine casing
Because of the wall’s thickness the fill was set to 80% for securing it not to be separate in the middle

3D scan an object (and optionally print it)

Each of us students had scanned another student head with a Sans scanner

Rounded Image

After scanning we exported the scanning files into Meshmixer software for fixing the models

Then we imported the models into Rhino in order to combining our heads into a totem and making a podium

We exported a STL file into Cura and made the Gcode for the printing in a Hephestos 2 printer
