3d Partial Exam

Here are the results from the survey we made






1 2 3

The car #1 was my car

The car #2 was the car of Claudia

The car #3 was the car of Marisa

The winner was # 1

Here are the drawings of the changes we propose

Here are some advance of the modelation the people told us they would like to see different lights, a hood scoop and a spoiler.
So far these what we have changed

Bye bye :)

Lesson 13

Once we have our cars ready we checked the survey with our teacher.
After it was aproveed we went to survey 30 people

The questions are the following:

Age: _____

Please observe the 3 choices of cars that we show you and then select the best answer:

Which car you consider that has a more youthful form?
Car 1 Car 2 Car 3

Which seems faster to you?
Car 1 Car 2 Car 3

What color do you think is the best?
Car 1 Car 2 Car 3

Which has better integrated its elements?
Car 1 Car 2 Car 3

If you would need to choose one of the cars according to you age, which would you buy?
Car 1 Car 2 Car 3

Which accessory will you add to the car you selected?
Different lights
Hood scoop
Two exhausts
Other ________________
Larger/different facias
Spoiler

Lesson 12

Last lesson we continue sanding our models in order to use the thermoforming machine.


first we cut the material, in these case we use PET but later we change it for syterene because we think its easier to cut and manage.
then we put the material in the machine .
The machine heated the material until certain temperature that we already programmed.
then we let the heated plastic fall into the models and we activated the suction.

finally we take it out from the machine and we separated the model from the plastic

we cut each one of the cars :)

Then we paint the cars according to the renders and finally we made a survey to see wich car will be choosen

11 lesson

In this lesson we learned about the Z printer.
The Z printer is in the laboratory upstairs. First of all the teacher explained to us all the devices, buttons and commands that the machine has and what they are for.

Then he explained to us step by step what we needed to do in order to print a model, what i thought was very interesting, is that in order to print there is a programme that checks the model a second time to be sure that everything is in order and it does not have any holes or errors; in these programm we can also scale, rotate ,duplicate etc

After doing this the machine accomodates the powder to have as little waste of material possible because the cost of manufacturing will be higher. The machine has a devide where all the material is collected so that you can use it again at a later date.

When the model is done you can apply resine to have a proper finishing. The resine has to be applied in equal proportions.

I think this way of making rapid prototypes is very interesting and useful to us as designers because we can have a very high quality and accurate prototype, however we have to be very careful with each step of the process and with the finishing.

10 lesson

In these lesson we prepared our 3 models and one extra for the Roland.
first we join the 3 cars each one of us already choosed.

Then we save the file in .stl
after that we opened the file in Modela player and we selected the devastation process and we programm it all in order to work with the Roland CNC.

After doing these we cut the MDF material and glue it .
Later we made and appointment for using the machine and we programm all the process in order to start our devastation process
Finally we have our beautiful cars in MDF :D:D:D

2nd Partial Exam

Last lesson we had our 2nd Partial Exam . we had 2 pieces , first we save them as a .stl file, then we validate the pieces in viscam view, later we opened them in modela 4 player, we took photos of these and we made a presentation in power point
here are some examples

8d lesson

7d lesson

Last class we continue in the redesing of our cars , we also learn how to save a stl file , how to use the VIScam view, and we made an exercise in Modela Player 4, this is going to be very useful when we make the definitive selection of the redesign of the cars

5d and 6d lesson

In the 5d lesson we had our teoric and practical exam.

In the 6d lesson we continue modeling our cars.
We join the 2 scans in order to locate the exact place where the holes are, this is important because these points should not move when we redesign our cars.

4d lesson

In this lesson the other teams were working with the microscriber digitalizer and others were scanning with the roland, we were working with the beatle we already scan and thinking how to redesign it.

3d lesson

On the Third Class we brought the cars that we already bought, in my team we chose a green beetle. We started to dissemble the cars until we had the main volume of the car. After that we started to put some lines with masking tape in order to make easier the scan with the Digitizer which we found not that easy. After scanning our car we went up stairs to know how Dr. Pizca works. Dr. Pizca is the program that we use to scan an object; we saw a very quick example of it.

2nd lesson

On the 2nd lesson we saw the presentations that we prepared about the different prototyping techniques, we started with the SLA (Stereolithography) which I think it’s a very interesting technique that it also made the 3d model layer by layer but the cost of these machines can be very expensive; other team also present these technique but they show us the applications in different areas like in the medicine to make models of the human body or in arts.
We present the FDM (fused deposition model) it also made the model layer by layer by adding the plastic from a nozzle, after that the model is merged in water to dissolve all the supports. Another team presents the Laminated Object Manufacturing (LOM) I was impressed by these technique because the models are built from glue backed paper material. We also learned about the open hardware which is a movement created to share different software to create hardware; some of these where very impressive because you can create your own 3d model machine in a very low cost compare with the others.
Finally we saw the Selective Laser Sintering (SLS) also to create 3d models but the one difference is that this machine can also print metal models.

In the second part of the class they saw the Digitizer and they also learn how to scan an object and they explain that to me, unfortunately I couldn’t saw it because of the meeting organized by SALDI.
