Next step in moulding models?

Just a little thought about modeling in general...

:cool: just was watching this programme about the newest printers, and they were experimenting with a 3-d plastic printer.
I was wondering, could this mean the next step inmodel car making?
First developping a 3-d model, "printing" it, and making moulds of it ?

This could mean we could have every model of every car ever made! and It doesn't seem so far of. Imagine within a few years the priices of those machines will be as low as computers, one with skill and dedication would be able to make models of every car he-she wants!

could this mean a revolution? what do you think ?

sorry about the size of the pic :rolleyes:

I was wondering the same thing myself. Ive seen art made by such a process and the results are very good.

A few years ago there was a japanese device called the Roland Modela which made 3d models out of wood. Seems like plastic is the next step in evolution now. Perhaps in the years to come we'll see rapid metal prototyping systems for the home user!

Modela is a 3d carving machine. It's essentially a computer controlled vertical mill. You can retrofit an existing mill to do the same task. It's just expensive.
What bigfrit is talking about is probably 3d printer. Basically, you have a 3d object on PC, and slice them in a constant pitch to obtain many section cut images, then print them on a surface, filled with powders that react with water from the printer nozzle. It keeps stacking the section images to complete the object.
It's a part of so called rapid prototyping. (try some google search.)
Another is to cut something with laser, and I've seen demo in person, but don't know much abut the technical stuff.

As far as I know, only Tamiya and Bandai is employing the rapid prototyping for sample models. The prototype of the Enzo kit, you saw in HLJ's show report was made that way.

I asked http://www.toybuilders.com/ to make a part, and this is the result. Can you guess what it's for? :)

looks like a rim to me...

A Nismo LM GT-1?!:confused: :D

A monza rim to go on the Enzo?

oh, and thanks for the info Hiro!

F & F Supra ?

What was the cost like ?

I came across the toy builders site once before, what are their costs for such a project?

where would the fun be? Unless it was for sprues. :D

At any rate, I've heard that Tamiya does all their designs in CAD (all computer), and then they send it to this machine the size of a small trailer home, that carves the piece out from a piece of metal - don't know the accuracy of that, though.

those machines that make the molds out of metal are very accurate.... down to something like 1/1000 of an inch or better... basicly you take a block of metal... send the machine the information through the CADCAM software. and it makes it. it will tell you to flip the block or change bits from time to time but from what know the result is nice. (if i try i can get access to this type). the other 3D printer works by turning a powder or simliar substance hard using a catylist. it does it in layers. those are also very accurate and can do complex shapes including a ball within a ball within a ball. so they do work very well, but are hell of expensive... hope that helps anyone.

Walter (wkma7six) gets to work with those rapid prototyping machines now. :cool:

He said it works with laser-cured resin or something...

mabe this will mean perfect fitting parts and no mold lines.

that sounds about right... i havent seen any since the trade show in boston i went to 2 or 3 years ago. but my dads company is having a model of a project made by one of those i think. (they own the metal making one)

About 350USD shipping and tax included. (ouch)
Don't worry, I'll get some money back by selling copies. :)
I needed to know if the procedure would work with my existing software, how long the turn around time was, and how the quality was like.

I designed a 3d model in Rhino3D, and converted it into STL file. It was sent to them via email for a price estimate.

Wheel is very difficult to make, unless you have a good milling machine and rotating table. But...come to think, two commissions of this kind ($700) would buy me a pretty good machine, so I haven't ordered another part since then.
But if I do it myself, it takes a lot of my time, compared to designing on PC, and time is not free, as you know it, so I might do it, when it's feasible.
FF supra wheel would be a good project, actually.

That is expensive! So what wheel is it?

Hey guys.
Yes, Jay is correct about the rapid prototyping system. Here is a link to what it is.

If you guys have a high speed connection, you'll be able to view the quicktime movie about the process. Its really cool. I'm trying to learn 3d Max in order to model my own rims in 24th scale. It can build pretty much anything, but round cylindrical objects come out perfectly-down to the tiniest of details. I'm having a blast at work playing with digital imaging. Oh, if you're wondering what my work uses it for - we use it for movie props and very detailed models that are used in the toy industry.
I haven't had much going on as far as models, but I'm trying to get things for Tamiya / con 2003.
