3D print test

We downloaded the Mini All In One 3D printer test and the 3D printer Tolerance Test, and to prepare them to 3d print and to generate the G-code file we downloaded Ultimaker Cura Software, the conclusions of the test are:

3D printer Tolerance Test

Design an object that could not be made subtractively:

Why it could not be made substractively?

Because the mulling cutter tool can't reach the four interior corners of the sides to create this pyramid shape empty at the inside like a shell and the only connection between the interior and the exterior of the shape is a small hole which is a big limitation to be made substractively.

I did a hollow pyramid inside with a hole in its base. I choose the pyramid shape because I wanna use 45 degrees angles to print without supports. The interior void allow me to put a light inside and create a beautiful effect like a lamp, at the same time allow me to use less material. The hole in the base was a suggestion of my instructor and allows the program to read the object as a continuous print, obtaining the desired result in the 3d print.

Design process:

3D print the pyramid.

To save time we decided to put all of our files together and print them at the same time.

You can download the files:

3D Scan an object.

For this assignment we scan ourselves using a Kinect device and the Skanect software. The process was really easy:

Conclusions:

3d printing is an additive form of production as opposed to subtractively process, one of the advantages is 3d print can create complex shapes that milling machine or laser cut can't. The limitations of 3d print are the time it takes because the object is created layer by layer.

Scanning technology is really useful to take objects from the real world and digitize it to be analyzed if we want a better resolution scanner the price increase but there are many options in the market and most of them are accessible.
