Thanks Andrew, Then it seem like the material is not so hard for sourcing. I've to look for Thermosetting polymer to play with, right ?by Buytaert - General
Mataerial It seem like the material solidified instantly when it cool down. I also think we could FDM with photopolymer with attached UV laser heads. Anyone have ever used or encountered this material before ?by Buytaert - General
When I'm thinking about details, now I'm not sure. But seem like See3d know how to do it already : ) And now I learn this thing exist instead LOL.by Buytaert - Polar Machines, SCARA, Robot Arms
And to make money from open source company, it's very doable. And my ideal world would be we, the reprap community, works as a one big company and the real competition will be shift to close source business. We can make money by revenue sharing model. The profits from fund raising, from sales can be distributed to all individuals who have committed to the specific machines, design, etc. One whoby Buytaert - General

Foam printing will change the world as we know it, a lot stuffs around me at the moment are foam. When someone talking about foam, I think about this and 4d printing every time. I like magic LOL.

The raft need little power to rotate and don't need much precision. Could we do it simpler with magnets ?by Buytaert - Polar Machines, SCARA, Robot Arms
This should be print with the gigantic Simpson : Iron Man, Urbee, Renzo Piano's Diogene / Studio Liu Lubin's Micro house. Then when the machine could use milling tool heads : Wikihouse. Frameless Geodesic Dome. OpenDesk. Gingery's workshop.

I've pledged on your project and willing to add some more for your goodwill, but I'm definitely don't have ten thousands. May I ask that the high cost will go for Reprap Peachy's development or just for company's profit ? I really like the company's Ethic statements. So never sell your company for profit, if it's a need then go Blender foundation route. Everyone should have choice to make and bby Buytaert - Polar Machines, SCARA, Robot Arms
I really like the company'sEthic statements. Everyone should have choice to make and bootstrap their own life. There're so much more meaningful aspects of work for companies than just to maximize their own profits. Companies should also work for mankind's profit, invest and profits more from physics, engineering, sciences and inventions. The values is up to how much they could do to benefit mankby Buytaert - Polar Machines, SCARA, Robot Arms

The best part of this is he seem like to open-source the software or didn't try to monopoly his new techniques. Multi- laser head for speed, accuracy and volume. Swarm 3D Printer! It's the 2nd 3D Printer I'm so excited and supportedby Buytaert - Polar Machines, SCARA, Robot Arms

The wiki is very confusing, almost unusable for newcomers without a lot of digging. Spam is not big problem if we do it right. We can assign moderators for each forum section / wiki, which volunteers can pick section they want to maintain. No need to do it all at once. Start small, section by section. Captcha / spam blocking will help a lot. Also, to create new user, just set 1/2 - 1 hour waitiby Buytaert - General
This is a very interesting product. Will there be a software that make FAX function talk to other 3D printer ?by Buytaert - General
@nicholas LOL my math is a bit off. At these rate, it won't be too long we need carbon nanotube structures. Turntable ? That's look like 3D scanner. jason.fisher Wrote: ------------------------------------------------------- > If the bed were on a turntable, you could maximize > the 3:4 design?by Buytaert - Delta Machines
Interesting idea. I also think we can use 4 crawler cranes / construction cranes like this : and at the center platform take one robot arm from this : It is complicated but I think it have potential to be another technique we build skyscraper in near future, for high budget project.by Buytaert - Delta Machines
@terribleperson I think we should begin with smaller one, find a suitable design for first generations. We only need a few generations for 3:5 Simpson to reach 1 meter arm length. To give rough idea how Simpson do macrocreation : For 3:5 Simpson (cm) 1st-15 2nd-25 3rd-41 4th-69 5th-116 6th-194 7th-324 8th-541 9th-903 10th-1509 For 3:4 Simpson (cm) 1st-15 2nd-16.5 3rd-18.1 4th-19.96 5th-21.96 6thby Buytaert - Delta Machines
About metal, until we have big simpson to play with, maybe sandmold is what we can sidestep with current design: If 3/6 arms Simpson can do accurate aluminum milling, I think it is enough to be a game changer.

I think their bulky design is limited by weight and super precision need. So there're rooms that you can improved. Thank you!by Buytaert - Delta Machines

Hello, I've been followed Reprap Simpson progress for a while, the machine is amazing! I'm new to 3D Printing and don't know much about it, but I would like to get one. I've some experience in importing electronic parts from China and Hong Kong. And I think the board pricing can be reduce a lot if you can find a reliable sources. It will take some time, but I'm sure it will be worth in long run.by Buytaert - Delta Machines
