DELLOS' CARS

Those are the three cars, the winner is the first one (Paola's car), the second one is Brenda's car, and the red car is mine.


In this picture we can see that Paola's car is cupe, my proposal and brenda's are "descapotado". The best model is Paola's car, and we are going to work with the z corp and with the print with Pao's car.



This is my car. It is a "descapotado" model. According to the survey, people prefer to use it in the city.




This is Brenda's car. Here we can see her proposal and it looks like a retro but modern car.

This is Pao's car and I think it is the best. As I said before we are going to work with this car for the final project.

In this picture we can see that there are many changes in the Pao's proposal.

Those are the cars.

SURVEYS

The last days we made our survey of our three propousals of the car models. we apply five questions for each car. Te ten questions were:

1. You think that this car is more adapted for:

a) City b) stand out(camp) c) careers(races) of cars

2. Which would be the best description for this car?

a) Elegant and sophisticated b) juvenile and sports c) common and basic

3. What would you prefer for the car?

a) Coupé b) Convertible

4. What do you think the design look like?

a) Modern b) got out of date c) modern but retro

5.- 5. You think that it is more adapted for:

a) Woman b) man

The results of the survey are shown in the pictures at the top. I depends of each propousal.

Reflection April 1

This sesion was one of the most interesting because we made our Termoformado with our cars. I thought that it was going to take more time but at the end it tood only 15 minutes. We had to "lijar" our cars and after that we made a holes around the car in order to get the propertly geometry. Now we have to pint our cars and make a survey in order to choose the best model.

Reflection march 25th

In this week we started to use the Z print 2.6. We got some instructions that are necesary to use the printer. For example, at the begining we have to select the units we want to work with. As weel as we have to justify our file, this mean if we want to transform, justify, or leave the model back at the bottom. Before to send the work we have to select the printer, that printer is called Zprinter310offline. In the evaluation process if suddenly appear some triangles in black means that there will be problems. Also we can get a print time estimated. In the machine that is in the room upstairs I could se that glue is in the tank at the top. An for the correct use of the machine and for get a good work we have to use others instruments like filter, hoover, resina and hardener.

Reflection March 18th 2009

The last sesion we set up our machining with the Modela Player Machine. Firtable we placed in the same file the three different proposals, one mine, brenda's and Paola's. it is essential to do that because with that file we will be able to work with the machining and with this file also we are going to be able to set up all the parameters for the exercise. The three cars were joined in the same file in Rheno, after that they were exported to STL files and then they were validated with VizCam View.

Here we start to set up the configurations of our machining. As you can see the three propousals are now in the same file. we have to be careful because our car´s size are ver small compared with the others. So that was the reason that we have to select a especific tool to make the machining.

Everything is ready to do the machining. As I said before we chose a 6 in tool because it is a small car and also because one of the cars has a different depth in the middle. We made the machining the last friday and everything ran with no problem.

Reflection 8th week

In this session we used the cnc machine. We got some advices how to use it, and some instructions for the propertly functioning of the machine. Before starting to use it, it is important to calibrate and try to find the center of the object. Also it is important set the machine in the correct way fitting the screws.

Cars proposal

In this proposal I added a roof. it was difficult because i couldn't make it as i wanted, but i tried to put a different design of roof.


I modified the rear of the car, exactly at the end. I cut some material as is shown in the picture. Before that the rear had the same shape, i mean a straight line, now is a curve line.



IN this proposal I put a elevation in the surface, exactly behind the passengers seat. It is difficult to view in this picture but it is easier to see the change in the STL file.

It was an interesting experince try to use the RHINO but at the same time was something difficult because I had never used it and I don´t have any knwoledge in any software of design.

Reflection 7th week

In this week we learned to use a software called MODELa PLAYER 4 that is used for aplications like CNC, Wheel and finishing. It is going to be a powerfull tool for our prototype because with this software we're gonna be able to modify the geometric of our car. This software has many steps in which we can find several options and several aplications according to what we want to get. We can choose the type of tool that we want to use. We are still working on our car and trying to make three differents offers for the next week.

Reflection 6th week

In this week we were working on our car. We tried to modeling our car in Renho and it was interesting because we had to use some methods that appear quite interesting due to these methods make easier the modeling. In my team Paola was doing the modeling in Renho and Brenda and me were giving some advices to Paola and that's the way how I'm learning more about Renho.

Reflection 5th week

In this week I made the exam. Some questions were difficult because I cuoldn't identify the correct answere due to I got confuse betwen microscriber and Roland Machine. At the end I knew my mistake and now I'am able to identify which one is better to use depending what we want to get. I still have some problems with the model softwares.

Reflection 4th week

This week was used to advance in our project. We tried to reproduce our scan in a 3d software, the problem is that I'm not used to use that kind of software. I don't have any knowledge of that software. I tried to make some figures by myself but it was difficult. We are still thinking in how to improve our car and it was another thing that we did the last week as well.

Reflection 3th week

The last class (28 january) we used a new machine and software called Dr Picza. It was quite interesting because the machine could scan very small pieces with much aqurate. Another interesting experience was that I could scan my car with the Microscribe digitalizer and I thing it is an excellent tool for scan but after using it for long time I got bored.

REFLECTION 3TH WEEK

In the 3th week of prototypes, at the classroom we heard several types of prototyping, some of them look quite interesting and I would like to know and learn more about them. On the other hand the others didn't look interesting for me. If I had to say something that I didn't like of the class, I would say that Sometimes I don't understand the topics because I'm not Designer and there are some words that I don't know what those words mean, but the next week if I would have a question I will asd for its answer.

The other think that I really liked was the software and hardware that was shown at the end of the class. Really I didn't know that something like this exists, and I liked that I could use it. It was interesting see how that is touched by the pencil is reproduced in the computer. It is interesting but perhaps difficult to use.

I would like to learn more about prototypes and I think the class turns ineresting.

THINKING IN PROTOTYPES

THINKING IN PROTOTYPES

An important step in the creation and innovation of new products consist in many designer ideas that at the end are represented in physical objects in 3D called Prototypes.
First you have to get a set of ideas for solving the problem or, in other case, to discover what you want or what you’re going to create. Prototypes are quite important because with that process you can find some mistakes early and with the experience you can fix them. Moreover with prototypes we are able to adapt or adequate the product to the costumers’ wishes, that’s possible with a set of pilot runs applied to prototypes.

Other step that is still important in the process is “Trial and Error”. It is really important because, as everybody knows, it is almost impossible avoid mistakes, but with trial and error you can find them early and often. Moreover, with trial and error, we can get some experience trying different ways to do the things and find out what works and stop doing what doesn’t works. Mistakes are inevitable, but if we try enough things we are going to find the best way to create or design the product. It’s for this that pilot runs exist.

Talking about Prototypes and Cad, the article says that the proliferation of design models has actually changed how Cad software is used. Rapid prototyping is much better than 2D screen rendering because is not enough. Moreover Rapid prototyping has become a form of dialogue between designers and their creation. Prototypes become an exactly copy of what the designer wants. But we have to be careful because prototype sometimes is not exactly what the designer wants.
