Printing with Ultimaker PC

[thelemurking 2]

Hello,

 

I need to print some prototypes with Ultimaker PC material, on our S5 printers. Was curious if anyone tried printing with some kind of Breakaway material as support(I have the one from Smartfill) and had success on small prints. Also, do you have any tips/tricks for printing with it? What settings do you use for support, when using PC as support, not something else. Any other tips?

 

Thanks a lot.

We are printing with Ultimaker PC I did make some adjustments to the basic profile to get good prints here is a copy of the profile from Cura. The biggest changes were to reduce the temp from 280 to 270 on the hot end, reduce the flow from 100% to 92%, reduce the flow for the brim from 100% to 85% (might even reduce that one by another 5%), reduce speed to 35 mm/s (for .1 mm resolution), and disable Z-hop.

 

For bed adhesion we clean the glass bed with rubbing alcohol and put down a thin even layer of glue stick while the bed is cold. And let the bed cool completely before removing the part - the part will just slide right off if you let it cool!

 

If you don't need super strong parts you can reduce the number of wall, top, and bottom layers - we bumped them up for super strong parts.

Hi Johnny,

 

Thanks a lot for the tips. I will try this out next time we need to print something using PC.

 

Have a great day!

Hi, do you print in black PC or in transparent PC`?

[jirodriguez72 19]

We are printing in black PC for added UV resistance.

Thanks :) I was asking because transparent and black/white are quite different, at least according to the technical data sheets.

You guys still using PC??

 

I am thinking of using it fro strong functional mechanical prototyping, 

 

Wonder if there's any new ways people are heading for this applications.

I am a little late to the party, but this thread came up when I was trying to find a way to improve the z-axis strength when printing with Ultimaker PC.  When I do a simple stress test, the parts snap right along the layer line pretty easily.  @jirodriguez72 I was thinking about increasing the hot end temp with the hope that the layers would mesh better, so surprised to see you lowered the hot end temp.  What was your reasoning?  Or does anyone have thoughts on improving z-axis strength, PC or otherwise?  Thanks, Alex
