We learned how to make configurations to run the printing process.

09/09/14

We were assigned in teams, in my case team 5.

Prof Mike encouraged me to see a way to put a fan in the printer support, in order to avoid the nozzle to overheat.

10/14/14

I took some measurements of the fan and pass it to a SolidWorks file.

10/16/14

I made in Solidworks, using a base of the nozzle founded in the Reprap website, a support for a fan. It ended up not being useful because the position of the fan was in one of the axis of the printer.

10/21/14

I talk to Ian and was looking for options to make a printer, fixing one of the oldest one. I decided to work with the printer Black.

10/23/14

10/28/14

I tried to work with the printer Black. I identified a few problems like one of the z axis is broken, it need a new nozzle and some balance ( put the same distance between all the axis).

10/30/14

I started to work in the new base to put a new nozzle in the printer Black. Ian gave me a file he have for a new base with a hole in the bottom, to fit the new nozzle. I edited the file and also tried to manually work or older bases we had in the lab to try to make a hole.

11/04/14

I had a lot of difficult to find a printer up an running, so I asked for an opportunity doing some design work and try to printer later on. I talked to Ian and he mention about the need of a gear.

11/06/14

Using SolidWorks I started to see ways to do the gear Ian showed me.

11/11/14

Another opportunity that showed up, was to fix a scissor that was broke ( one of the cables). Prof Mike gave it us so we can figure out what to do next.

11/13/14

We tried to clean the scissor, by removing the rest of the plastic of the previous cable. Try to remove it using tools wasn't very efficiente ( more details later, in 'Extra Projects').

11/18/14

11/20/14

12/02/14

We did the quiz and started to work on the printing service.

12/04/14

12/09/14

I finished the model of the gear and sent it to Ian. Also , my group continue the printing service process. Gear.JPG

EXTRA PROJECT - Scissor Repair Summary – Professor Mike gave us a scissor that after several use ended up breaking one of the cables. The challenge he gave us was to use 3d printing, fix the scissor. Step 1 – Preparation

The first step was to remove rubber from the broken part of the cable. We tried to cut but the material was too strong. In order to remove it, we put in the fire, in a very slowed and controlled process, heating up, putting in cold water and then trying to scratch the rubber. The process took about 15-20 minutes.

Step 2 – Project

Later, after take some measurements we tried to model the cable in SolidWorks. Two versions were made, a simplified(1) and a more ergonomic(2). The reason of the two models is see which one will be more reliable in the manufacturing (printing) part.

1 - Simplified version


2 – Ergonomic version Step 3 - Manufacturing After the project in SolidWorks done, we exported as a STL and printed in the printer Beta. The result was the following:
