MDF PIECE

This is the MDF base piece obtained from ROLAND to be thermoformed.

Thermoformed cars

These are the three different thermoformed car models we used to make surveys in order to choose the best one that matches with our parameters:

• City car
• Elegant and sophisticated
• Cabriolet
• Modern
• For women

Last session was about obtaining a plastic piece in order to have a physical sample of the final car and test people about it.

Once we had our MDF car from the roland printer, we finished it and spread it with soap before using the thermoformer. We had to take care of every detail in the MDF piece because the melted PET would be a copy of it and sometimes you cant get specific lines and foldings, so we have to choose a determined thikness of PET and calculate the temperature of melting.

Then we have to cut the rest of PET and get the piece in order to mask it and paint it like the render we made before.

Having the three cars ready we aked people about some characteristics of the car so we could have an idea of the best car to be made in the z-print.

• Last class we went upstairs to the rapid prototyping lab where Raul show us how to use the Z-corp printer.
• It is a machine that works with to principal elements, glue and dust; and it is connected to a computer from which it receives information to be printed.
• We have a 3d model that is cut in many layers horizontally in the computer and then the printer works layer by layer, dust-glue-dust-glue... until the object is done.
• Once the printer has finished we have to wait 30 min and then take the object with a special tool and put it into a chamber where a vacuum cleaner is going to absorve all the extra dust.
• Then, as it is a fragil piece, we have to be careful, but in order to make it hard we have to add a mixture of resine and hardenner with a brush and let it dry, then the object is ready.

Last class we learned how to use the Roland model printer, we went upstairs to the lab in order to be teached. Roland is a printer that can work with different materials such as MDF or acrylics, etc. The first step is to place your material on the surface and hold it in order to locate the taller part with the sensor and the center. Then you have to make a conection between the computer and the machine. We have to be sure to close the door, if we dont do it the machine wouldn't start working. The files have to be .stl so the Roland modeling program can read them.

ORIGINAL CAR "Prowler" by Chrysler

This is the basic model that I tunned.

Car Model 2

This is my second car model, it has a roof with a window and the truck doesnt have any details, is a simpler surface.

When I exported it into an .stl file and test it with visCam view it appeared to have just some right (green) surfaces but many different normal directions of surfaces and unmatched edges.

Car Model 3

This is my third car model. It has a different front with "calaveras" and "salpicaderas", and it only keep the detail of the "escape".

When I exported it as an .stl file and examinated it with visCam view program it resulted with many different normal direction surfaces and also unmatched edges.

Car Model 1

This is my first car model, it has a different front (parrilla), three details on the truck, side lights and in the down part of the truck it has a fixed exhaust in order to appear more intrepid.When I exported the car to an .stl file and analized it on visCam view, it appeared to has many errors as different normal directios in almost all the surfaces but parts of the door and lateral mirros, and there are unmatched edges as we can see with the yellow lines.

Last class we learned how to convert and export a file from rhino to a .stl file so it can be read by a solid printer. We had to convert our model of surfaces to a mesh so it could be understanded and triangled by an other program called visCAM view. If the image appeared with different colors and divided with many lines, it has to be meshed again in a more triangled way.
