Facil by Santi Fuentemilla

The assignment for this week is to scan something, modify and print it with 3D printer. I made to exercices with diferents machines. The first one is with the MakerBot and yhe second with de Fab@home.

3D scan - 123D Catch

123D Cath

Basically, this program uses photos taken by a standard camera to create an object in three dimensions. You can download from here

This program is only available for windows!! In future versions will be available for Mac too

Recomendations:
-Tries to do a lot of pictures from all angles possible.
-Do not make sudden jumps between photos
-Uses reference objects

Finally I exported the object with extension .obj

Rhinoceros

I opened the object .obj

To remove the faces i selected from the menus - Mesh/Mesh edit tools/Delete mesh faces

To cut the base and cup a face i selected - Mesh/Mesh boolean/difference

Finally I exported the object with extension .stl

Process

3D pinter - MakerBot

Software and drivers

You have to download the Replicator G Windows and for Mac

To generate the G-Code you have to install Phyton.Windows and for Mac OS X

Replicator G Configuration

I Selected the machine in the menu - Machine/Machine type/Cupcake

I moved, scaled, and rotated the object until the desired size

Then i generated the G-Code. You can choose differnets settings:
-Base profile: SF35-cupcake.HBP
-Use Raft
-None support material
-The other settings i used by default

Finally in control panel i defined the target temperature (220C) and the platform targed temp (130C). And i set manually the extruder to (0,0,0)

Printing

-First attempt: It didn't work because, i dond't know why...

-Second attempt: I forgot to leave enough material and finally the extruder ran out of material.

-Third attempt: all ok.

Final results

3D printer - Fab@home

Heloisa Neves, my coleague at Fab Academy and I decided to use the Fab@Home for this assignment. The objective was to scan a pice of cholocolat and printed with chocolat too.

But we had many problems from the start.
I'll just count the steps we take very schematically. If you want to know more, Helosia documented the whole process super well on his website.

Software:

First of all we downloaded the following programs: FabStudio and Fabinterprer.

The also we downloaded the printer configuration.

Configurtation:

We had to modify the file called "Duel Syringe - Model 2.config" because we had to set de "COM Port". In our case i was port 2.
