My @3DBenchy , dual extrusion model, on my own design Cohesion3D printer with 10x10 heated glass and dual E3Dv6’s.
I chose blue and yellow because they mix well, so if there was an issue we would have a very distinct green blob on the printout.
Sliced with Simplify3D using an ooze shield and prime pillar, the pillar fell over about half way through so that’s where all the “hair” is from.
I’m still playing around with the retraction settings a bit, as 6mm on tool change leaked a lot but 12 is too far in and causes clogs. I’ve just started another print of this using 8mm on tool change and lowered the temp a bit to further decrease ooze.
Overall, quite happy, especially with the crisp color separation.
.2 layer height, 2 perimeters, ESUN PLA from microcenter, and some very good cooling.
Of the machine? $2,000 USD. I do custom work right now (for example a 24x48 inch sized machine with 4 extruders and auto bed leveling for a client: https://www.dropbox.com/photos/shared_space/Cz1WXooQX6IdSq8) but am perfecting this design to start mass selling specific models.
@Peter_Lewkowicz the part I didn’t mention is that I’m working on an extruder for conductive ink to print circuitry inside plastic. So, 10x10x10, heated bed, 3 extruders in total (2 plastic + 1 conductive), and the ability to integrate electronics inside your designs is well worth the $2k when the next nearest competitor is 9.
Indeed. But I still need it to be the best printer out there which is why I’ve spent over a year on this particular design, and it’s all I use. The stationary bed, in particular, reduces a lot of vibration, prints don’t shake off the bed, and leveling is easy. Plus, because the bed doesn’t move, scaling up is easy. I’ve gone from 12x12 to 24x48 (and working on even larger) and everything in between.
Yup. There’s also a complete breakdown with 17 or more files for each individual component of the boat if you had more than 2 extruders you wanted to test…
