wow :cool:
that is fantastic work .

Did you make that John?

if so..... can I commision you to make one for me please?


AshG 21st April 2010 09:54 PM

is that one of them 3d Laser Gel Thingies.... I think we are getting one next year...

I printed it on a rapid protoyper last night, not cheap but beats any executive toy that has graced my desk before.

The tubes for the wishbones are actually hollow and some of the chassis rails as well, ideally would need to be redrawn solid as it is very fragile. Would also benefit from printing in a different colour such as grey but would have meant flushing 40 to 50 quids worth of resin away to change.

For those not familiar with rapid prototyping it is basically a 3D printer that works similar to an inkjet but builds layers of resin instead of ink. The resin is then cured on each pass by UV. It can print any .stl file, if you can CAD it, it can print it (up to approx size of a modern microwave oven. It's what the F1 teams (and other companies use) to prototype parts. Again not cheap, but incredible technology.

I think that your refering to SLA technology which is a different method of doing the same thing. We put in a lot of research before settling on the machine we purchased and would be happy to discuss what we found to be the pro's and cons of each technology/machine. What line of business are you in?

Education I.T. Support, Someone in the technology department mentioned them a few months back I remember seeing the original ones on Tomorrows World!!!

In 10 months time my office will be next door to the workshop and I am hoping they may replace more equipment ;) a nice CNC miller would be nice :)

OMG that's fanBl**dytastic.

I think you better get ready to go into production we all what one!!! Go on name your price.

Super cool
Thanks for sharing that with us John :)

I had no idea that sort of technology even existed :o :o

Must bring a whole new dimension to prototype work :cool:

Bl**dy Hell John, that is excellent.....:eek:

Can i have 10 please.
