First complex print on RepRapPro Mendel - 12 years ago

I assembled the printer over Christmas, got a couple of excellent test prints and then it all went to pot. Improvments to the temperature control, and a higher extruder temperature brought things back and here's my first 'complex' print, from Dizingof on Thingiverse I'm very pleased with this, but still need to get properly to grips with Skeinforge - it's frustrating that the tweaks you make

Re: Metal-print Reprap - 12 years ago

There are lots of problems to using another material for printing besides "can I melt it?". You need to ask - When I melt it, what is it's viscosity? Will it maintain the extruded shape during deposition? How quickly will it solidify? Will the heat of new material melt or weaken existing layers? Will layers bond effectively? Can I feed the unmelted material easily enough? and so on... In many

I very much doubt that - there are a series of large, high profile Kickstarter projects that are court cases waiting to happen. If they were to settle, that would weaken their position for the next case, and the one

Re: Uh Oh, formlabs is a no go? - 12 years ago

If I understand it right, including Kickstarter in the case is unlikely to get past the first round of lawyers - it's like Apple taking a patent case out against PayPal for allowing people to buy a Samsung Galaxy. The worst that's likely to happen is that any future sales are blocked. Otherwise, it's not surprising that a company selling 3D printers for $30,000 should try to stop another company

Re: Product development startup - 13 years ago

Thanks for the few responses I've got so far. It'd be good to hear from a few more people who've gone into making parts or even complete printers, as well as those of you who've used a RepRap to help build a completely different product. There seem to have been a few interesting failures as well as entirely new printers developed around the core RepRap concept. That adds up to a lot of experienc

Product development startup - 13 years ago

This is slightly off topic, but I hope some of you might be able to help. There is some amazing work on the RepRap scene, both in design and fabrication of printable objects and in the printers themselves. I am in the (very) early stages of a startup, with the aim to create a service that helps people fund and create innovative new products. So I'm looking to chat with people who've developed t

'Ink' pen allows flexible circuits to be drawn - 14 years ago

Re: How do we both encourage RepRap mutations and stay focussed? - 14 years ago

Hi all, I'm new to the forum and reprap, but have been around various homebrew and software scenes for decades. Hopefully you won't mind me rambling here. Comparing RepRap to the PC scene is rather skipping a few generations. It appears closer to the home micro scene of the 70's - where standards emerged as groups found consensus on the 'better' technologies to use. Before the PC established it
