Mm mm your delta are semi complete 
why the push rods are so long?
Hi Thomas, please could you advice me with the best 3D multi color printer for making a small person models which can give high resolution but maximum of 50 cm height and can work with most available materials thank you.
Honestly I couldn’t take my eyes off your delta there. Any info on that?
@Ayman_Helmy , Thomas is inundated by questions like yours and is not likely to reply. There are several 3d printing faqs you can locate through Google. The 3d printing G+ group is working on on but it is still rough.
@Ayman_Helmy @Mike_Miller is right. Tom is a busy guy and honestly Google is your best friend for questions like that. There is a ton of info out there you just have to dig a little to find it.
Perfect Tom!
I will certainly be pointing people interested in starting 3d printing to this. I particularly agree with the need to learn some form of 3d modelling software.
Keep up the great work!
Very true. I’ve had a few people ask me if I can build them printers. After the Yes I tend to explain some of the details you discussed and find that without fail interest dwindles. People expect a 3d printer to be a photocopier. they don’t comprehend that if they want something decent they are first going to have to learn cad. or at least put in the time to learn more.
Perfect !
