Assignments
Group Assignments
- Test the design rules for your 3D printer(s)
- 3D scan an object (and optionally print it)
- Design and 3D print an object (small, few cm3, limited by printer time) that could not be made subtractively.

More specific detailed from the worked done with Ernesto Castro in Fab Lab Universidad de Lima here
3D Bambu Lab X1 Carbon Printer
3D Bambu Lab printer parts.
The 3D printers we have are the 3D Bambu Lab X1 Carbon Printerthat have a printing area of 26cm height max. It works with an app called Bambu Studio and works with lots f filaments, generic and the ones from bambu. In the lab we tried with PolyLite PLA, generic TPU and PETG.
To use the printer we have to follow some steps:
- First, Install the app Bambu Studio.
- Charge the material in the back of the printer
- Upload the material settings according to the fabric settings.
- Select your file with the SD card. upload the settings and start.
- Don't forget the base of the printer. It must be clean.
Phrozen Sonic Mega 8K Resin 3D Printer
Resin 3D Printer parts
We also have a 3Phrozen Sonic Mega 8K Resin 3D Printer That works with liquid resin so we have to use gloves and a mask to protect ourselves from the resin. This works different because works with UV rays projecting the layer to print and maing solid the resin.
To use the printer we have to follow some steps:
- First, Install the app Chitubox.
- Charge the material in the back of the printer
- Upload the material settings according to the fabric settings.
- Select your file with the SD card. upload the settings and start.
- Don't forget the base of the printer. It must be clean.
We decided to make the material and settings tests with a voronoi sphere that isnot solid and with different thickness. From 0.2mm to 0.4mm in Resin, TPU, PETG and PLA (order image above). And to see what material can make the sphere bounce more.

The object needs supports to be stable in the printer. As it goes from down to above. The sphere needed a lot of supports since it is not solid. We chose the tree auto supports first and it were inside the sphere in PLA, which was very difficult to takeout.
Then with the TPU test we try to make manual the supports and only chose from the middle to the base and only outside supports. We tought it will make an error and not print but it went well! An here you can see how malleable is the TPU.
INDIVIDUAL ASSIGNMENT
Luma 3D Scan
Model from Luma app
I knew this app called LUMA 3D for IOS that scans by photo 3d objects. I used in Graphic for architecture classes to show the students how you can digitalize 3d objects scanning and then modelling to be even more precise. So, with this app I scanned a geranium of my moms collection. Then clean the 3d model in Rhino and triangulate the mesh and make thickness with grasshopper.

Resin 3d printing
Curing process To take put the resin printing first it has to take put any rest from resin with a machine that cleans with isopropyl alcohol. And then it drys with another machine.

Handy Scanner
In the Fab Lab Ulima they also had a 3d scanner. I tried to scan 3 different objects with it to test surfaces. First, an object with fabric, then an object with gloss black plastic and then and object with matt bright plastic.

The scanner did't detect the fabric at all. We believe it transfers the light and cannot recognize the laser at all. It only worked in the first layer of the plush. We tried with low light and also a uniform color base to not distract the laser but it didn't work.

I started my final project testing the form of the final lightstick. The base where all the leds will align and coordinate color combinations. I printed this first idea of a base tree kind at 50% scale to test the angles.
