Re: World-wide reprap printing webstore - 16 years ago

I think the idea is a good one. It was actually similar to what I wanted to propose. It's not just about making RepRap parts available to those who want a RepRap. Anyone with a RepRap could sell services and earn back some of his expenses if he wants so. It's usually way too much trouble to start a webshop yourself, but for this there could be a central (middleware) platform on which demand and s

Extruding in a liquid - 16 years ago

Hi, When I thought of water soluble support structures (great concept), something made a click. I had the (crazy?) idea of extruding in a liquid (e.g. water, oil). It may sound crazy, but bear with me... I want to try it, but I'm still waiting on parts to start building the RepRap Extruding in a fluid has two main implications: 1. Flotation support: If the level of the fluid is controlled, th

Hi Satuna, Could you give an indication of how much (for example) all the thermoplast parts for a RepRap would cost? I think there is considerable interest in this. Regards, Erik de Bruijn

Re: How long to get started with RepRap - 16 years ago

I'm only halfway the project, but through the BoM (bill of materials) it is really only an evening of reading what you need and ordering it with a few clicks. Two days later you can start soldering up all the equipment. Your son certainly seems capable to do this. With some patience I think many kids CAN do this. That's the beauty of this project I think. Good luck with it! I think it is great t

Re: RepRap Darwin CAD Model Files STL, Solidworks, max, 3ds? - 16 years ago

Thanks spcmicro. Neatly done! I think that making the RepRap and its software aesthetically pleasing will improve adoption and make it more end-user ready. We need to take these first steps.

Re: Say Hello To Slashdot. - 16 years ago

I think a recycler (I know, idea has been around here for a while) would definitely be a unique selling point (besides the fact that the point is not selling the machine). I'd definitely want to reduce my household waste AND reduce consumption of my RepRap! Since us humans create infinite amounts of waste, turning this liability into an asset would be nice for a change. Regards, Erik de Bruijn

RepRap counter - 16 years ago

Hi, I'm thinking of creating a "43th Registered RepRapper" (for example) icon system such as linux has: I've worked with GD in PHP (graphics library) and could set up counter.reprap.org to get an official count of the amount of RepRappers + amount of RepRaps in existence? We could distinguish between RepRap user and developer and allow people to change their settings, amount of Darwins and g

Re: RepRap Darwin CAD Model Files STL, Solidworks, max, 3ds? - 16 years ago

Could such a file be exported to a non-proprietary format? Would be great if that were possible... I've just gotten myself a little more familiar with Art of Illusion. It imports: - wavefront (.obj) - stl - Digital Elevation (.dem) - ASCII .dxf - Videoscape .geo - Lightwave object .lwo - POV tree mesh (.pov .inc) - 3D studio object .3ds Erik de Bruijn

Mirror (+backup) servers - 16 years ago

Hi again, I'd love to run a mirror of the RepRap wiki and perhaps some more stuff. The mirror would be to handle slashdotting more easily (my (co-founded) company has 5 gigabit uplinks, though actually fully using them would be quite expensive). Besides simply bandwidth and accessibility of the information, I'd like to ensure that this (ever growing) valuable knowledgebase is not lost: a backup

RepRap logo - 16 years ago

Hi, I've traced the logo to SVG and manually recreated the sharpness of the fonts. I wanted to create some logo pictures in several sizes. In this tarball are the SVGs, some exports and a windows icon (64x64): I guess it would be useful to put this on the wiki somewhere (also for promotion purposes, most magazines prefer vector based logos over the small web-gifs) If someone can, please give

Free microchips for prototyping (1 gen electronics) - 16 years ago

Hi, For those who don't know: Microchip.com offers the ability to sample their products. This allows for a limited supply of 16F6x8(A) chips. For a single RepRap it would be a nice way of reducing the price of the total system a bit. Since you're really prototyping electronics in order to develop a system that will be massively adopted I don't think we need to consider such small amounts of samp

Re: The extruder motor and changes needed in extruder robustness - 16 years ago

Hi, I think it might be wise to go for a modular approach: 1. Make a system to create thread from granulate (I read Adrian's article about rolling threads by hand, but I guess this is limited to the lower-temp 'friendly plastics') 2. Create an extruder head that uses this thread 3. Work on compatibility of these systems This way the thread creation can be improved independently of the current e

Re: Does an object need to be fabbed all at once? - 16 years ago

If the RepRap would be more contained (e.g. acrylic panes on all sides) you could make a heat regulation system. But I'm not sure if we hit a fundamental problem: the RepRap cannot make whole panes as big as itself. Transparent material would be desirable as well, and I haven't seen that. On the other hand, if it cannot make things such as screws anyway, nothing changes, since acrylic/glass panes

Introducing myself - 16 years ago

Hello all of you, Firstly, Adrian Bowyer, I'd like to say that your idea of a replicator and your speech about it really gave me a tingling sensation down my neck. It's one of those ideas that is not just pretty neat, but really something I want to be part of and help out with. I've actually had trouble sleeping because I had so many improvement ideas (which I'm all writing down). I'm Erik de B

Re: The Epic Has Begun!!! - 16 years ago

Hi Jay, Where did you source the RP parts? You parts look great even in the close up pictures. I'm currently ordering with Ian (BitsFromBytes.com) so I can only guess what quality I get. I do have faith in Ian that he does his best, but it's hard to know what to expect still... Regards, Erik P.s. saw the EE PC at CeBIT, great little thing you've got there.

Problem running the host software [solved] - 16 years ago

Material: Polystyrene - 16 years ago

Hi, Since I'm waiting on shipments to start building the RepRap, I have been trying to make and evaluate plastics as a source material. I have been trying to make them from starch by adding vinegar and some glycerin, but the result seems to lack real plastic properties such as strong cohesion of the material (it's still crumbly). I used these instructions: Then I found another instructable to
