RepRap is humanity's first general-purpose self-replicating manufacturing machine. It is an open-source project that focuses on the creation and development of 3D printers that can print (some of) their own parts.

Air Duct Placement

by Ianmark

Where is the best area to aim the air duct? Directly below the nozzle, around the nozzle? I see air ducts that aim the air in different locations and I was wondering what people thought of this. I need to print a new air duct, so I thought I would get some opinions.

Thanks,
Ian

300x300 heatbed

by valand70

Does anybody have a detailed drawing of a 300x300mm heatbed ?
I need it because I am expanding my printer and would like to design the parts first.
I found on Aliexpress many hotbeds but no one specify true dimensions and holes interaxis...
There are probably different makes, but I hope somebody has one of these reprap mk2a or mk2b beds and can share dimensions...

Warped Bed

by Ianmark

The bed on my FLSUN is warped. It's higher in the middle than the sides or corners. I am looking for a new heated bed, but looking on Amazon, how do I know if it's going to be a decent bed?

Any suggestions?

Thanks,
Ian

PVA + PLA / HIPS + ABS With Single Nozzle Dual Extrusion

by Mysterious_Wanderer

Looking to add dual extrusion to my delta printer, however the small degree of effector tilt they all seem to have no matter what makes this a problem. I have seen systems on hotends that rotate with a servo, raising the unused one but there are no real guides on how to do that and I would have to design the system from scratch.

So, can something like a E3D cyclops or diamond hotend print these 2 materials? Lets say that I want to print the pva at 10 degrees C lower than the pla. The pla would definitly still be able to pushed out of the hotend and added to the waste tower, but is there support for what I want to do in S3D or Cura?
