Rapid Prototyping - TinGoat - 05-05-2010 Hey Kids, Are you looking for a specific prototype that's not commercially available. Here's the answer to your prayers. I found the link to this website on the Monorail Society's Yahoo! Group Quote:Monorail models Quote:These are N scale bodies for Dutch train models. Totally amazing!!! <!-- m --><a class="postlink" href="http://www.shapeways.com/hisdesign?user_id=16518">http://www.shapeways.com/hisdesign?user_id=16518</a><!-- m --> Re: Rapid Prototyping - TrainNut - 05-05-2010 That's neat!

Re: Rapid Prototyping - Sumpter250 - 05-05-2010 nachoman Wrote:Kind of takes the fun out of things when all you need to do is say "computer...make me a ..." Whoa !! That imparts a whole new meaning, and consequence, to the phrase " Be careful what you wish for". Think about it.....you're standing there saying "computer...make me a..." as a mosquito bites you and you mistakenly say "dratted mosquito !!"...................and never complete the move to squash it, as you flit away. Re: Rapid Prototyping - AF350 - 05-06-2010 Hi all, look at Makerbot's 3D printer it has a small "print" build area but is an open source both hardware and software wise DIY CNC/3D printer uses ABS as the material to build/pint with. http://www.makerbot.com/ Re: Rapid Prototyping - twofoot - 06-06-2010 Makerbot's machine is an amusing concept at most. The resolution is MISERABLE, and cannot even be considered for model railroad use. Even the machine Shapeways uses leaves a lot to be desired. If you want "ready to paint" parts, you will need to output on a Viper or other high resolution machine. But solid modeling and rapid prototyping are definitely cool. Almost every commercial model available is made on the computer now, and the injection molding dies are then cut on CNC equipment.

In fact, they'd be comparable to...or cheaper than...the existing commercial trucks in the case of O scale. I expect that rapid prototyping/3d printing will eventually dominate the craftsman kit market...for it is already competitive with the labor costs of resin kits in some cases. Re: Rapid Prototyping - tv_man - 06-22-2010 Having followed the progress on the forums where these dutch prototype models were (and are being) developed and built I can only agree that this is quite cool, but the surfaces really, really need a lot of work before they come even close to acceptable levels of graininess. The technique seems to be useful for odd-shapes (organic forms, round forms, that seem to be in vogue on modern rolling stock) as those are quite difficult to do (consistently) using brass or styrene, but for smooth surfaces traditional techniques still seem to be better. Eventually we'll probably get fully painted models out of the replicator, which will take a lot of fun of scratchbuilding with it.. |
