What is the best adhesive to use on a heated build plate? Ive been using glue stick and having some issues. Ive seen a spray mentioned on here before that is really sticky when its heated and not sticky at toom temp which sounds amazing for printing abs. Anyone know what it was?
PEI pretty nice material as a bed surface. No adhesives required. Just have to clean it with rubbing alcohol regularly.
I’ve been using 3DLac with ABS prints. My prints stick really well and simply pop off the bed when the heated bed cools down after a print. Also it costs only about 9€ for 400mL.
You can also try conventional hairspray but I don’t know if this works for everyone.
I personally like ABS paste on Kapton. A little bit goes a long way and it is a good way to use some of your bad prints.
Abs paste is good. I just dont like having a different color on the bottom of a part than what the color of the part is. Unless i have like 7 different jars
I second having PEI. I no longer have a consumable when using ABS for my bed.
I’ll have to look into that pei bed. I have a davinci and im scared to take the glass off of the bed… It has a small chip in the glass so ive been looking at different choices
You just add the pei to the glass
Oh. Can someone explain what pei is?
PEI is polyetherimide (trade name Ultem), a super-plastic that is chemically very similar to Kapton. Except instead of just coming as a flimsy adhesive tape, you can get it as sheet and plate stock. That means it’s durable enough for permanent use, either as a plain plate (expensive) or a thin sheet laminated to something flat like glass using high-temp double-sided tape (such as 3M 468 or 9472LE). And in my opinion it sticks better than bare Kapton too.
I use PEI on my printer and our works really well for every material I print. PLA sometimes needs the print surface to be sanded for best adhesion and it does need to be cleaned regularly with IPA but I don’t have to change surfaces when changing materials.
I use the purple glue stick, but I never wash the glass. I scrape the excess glue off before reapplying before each print, but there is residue from old glue. I suppose it is like sanding the glass, because the surface is not glass smooth but I haven’t had a part lift off in many months. I heat the bed to 45 deg. C. Even large prints stick good.
For PLA I use a UHU glue stick - however it also needs a bit of extra rubbing.
Initially the applied glue is very slippery, but I then I use a curved spatula to firmly rub over the glue. After a short time the slipperiness goes away and the glue starts to get very, very tacky.
It takes more rubbing to make it tacky in colder weather (it’s mid-winter here in Sydney), so I apply the glue after I have warmed-up the bed a bit.
The result is so sticky that several times I have broken my prints trying to get them off the bed.
Hi Ryan. I use non-aerosol hair spray, it’s clear and very sticky. However, large prints still lift at the corners. No problem with small (70mm or so) prints. I clean the tray to a polish finish each time, then apply the hair spray. My tray hasn’t cracked but has imperfections at the centre, ie it isn’t flat there. I have to let the tray cool to near room temp to get the item off, they get stuck hard when it is hot.
+1 for purple glue sticks. Large prints are an issue because the bed temps fall off towards the edges. I normally increase bed temps once into the print for large objects and also cool down the print gradually by reducing the temps by 5 degree intervals every 10 minutes or so.
ABS juice made using translucent or white ABS. Any that is on the finished print, just a quick wipe with acetone.
Depends on the material for me. I use kapton for PLA and 3M tape with a glue stick for ABS. If a print starts to peel I stick it back down with a hot glue gun. I’ve saved roughly half my prints this way. ABS juice is great if you’re only printing in ABS and on a semi large machine. If you’re using a different material it will do nothing to help adhesion and if you have a small printer it becomes very difficult to take off the prints and you can wind up damaging your printer in the process.
