I have printed with almost every material now and testing more everyday but I finally got around to testing HIPS.

Now I know settings change from printer to printer and from spool to spool but what setting for the bed temp would be recommended? Or method would be recommended to have the print stay adhered to the bed?

I have a Robo3d R1+ which is a open printer with a heated glass bed. I currently use a glue stick.

As a starting point Hips is widely used as a dissolvable support material for ABS. Your bed settings for ABS should hold hips just fine. I have yet to find a material that doesn’t like glass with aquanet or super glue. Others with more experience printing hips standalone might have different advice.

Thank you! I just can’t seem to get the prints to stick to the bed well. Its sticks enough to finish the job but I seem to get warping most the time and the print just falls off the bed.

What are you setting your bed and hotend temp at? What’s you first layer height and width? And is this a model you have printed in ABS before?

I set my bed at 90c. I basically used settings that I use for abs except I adjusted the nozzle. I haven’t runt the model in abs but I have with other materials

Can you describe the model a bit? There are a lot of things that just don’t print well in open air with ABS/hips and other high temp high skrink rate filaments. If the model is warping due to the design you could add a brim to the model or the print and see if it helps. Also this thread has some q&a and settings for hips prints Talk Manufacturing | Hubs

Its is literally a flat 6 inch x 4 inch rectangle. Its not just the one model it is a common problem with whatever I print. None of the prints have needed a raft or a brim. I have also checked the distance between the nozzle and the first layer. and made adjustments with no luck.

and my problem isn’t with layer adhesion.

Are you using a layer fan? Try something like a 15 degree higher bed temp and 15 degree higher nozzle temp on the first layer and then lower them for the second and above. Again it still might warp because it’s an open build area. You could also try enclosing the build area with lexan or evil acrylic. Or cardboard. You could also use super glue or ABS juice both of which will make a mess and have toxic fumes.

Hey! I have a Lulzbot Mini, and I really enjoy printing with HIPS.

However, I usually have to kick my bed temperature up to roughly 110 degrees celsius for the HIPS to stick. If your print bed can heat that high, than try somewhere around 110 degrees. The HIPS sticks wonderfully to the sheet of PEI that I have on my Mini, and I haven’t had any problems so far.

I hope this helps!
