POM + Prusa i3 MK3 = ?
Hello,
as the topic suggest, did any experiment with acetal/ delrin filament was sucessful on new 3d printer? (I'm not the owner - yet - of this printer)
I'm trying to find some working, 3d-printing hardware set up for this filament.
Tried to print on glass, tapes and texturized platforms (plastic ones, like this in Makerbot Replicator Z18), but i can't make my prints stick to bed.
Generaly I tried to print POM on not heated beds, and I failed.
Would appreciate any tip in this regard.
Thank you all in advance for any advice.
Re: POM + Prusa i3 MK3 = ?
I dont have my printer yet either, but do have a friend who has used this material in the past, he doesnt anymore due to its difficulty to print.
But he has said his best results were with it printing on a glass surface heated to 160C, hotend 240C, high on the fans. He said they only way he got it to stick to the bed was if the bed was very close to the glass temp of the filament. He was using a i3 clone with alot of upgraded parts, he had to design his own heatbed just to hit the temps needed for this material. He also mentioned to me when i brought this up that it releases toxic fumes and to ensure printing is either done outside, or wear a full face respirator.

Well... this is HUGE temp to achieve on building platform.
I am comfy with fumes, as these can be more or less prevented ( ventilation ) and do not bother with hotend temp. since specs of i3 MK3 tell me it can reach even higher ones.
Question is : Is it possible to reach such temperature on regular Prusa i3 MK3 kit (standard magnetic heatbed mk52)? Or there must be some upgrade in place to achieve this temperature?
@josefprusa Would you like to elaborate on this topic a bit? Would love to know your opinion in this matter.
Re: POM + Prusa i3 MK3 = ?
Does anyone already printed POM successfully? I've seen some cheap POM and wondered if I could print on the standard i3 MK3.
Re: POM + Prusa i3 MK3 = ?
Heatbed temperature on the MK3 is limited to about 115C, hot end 295 max.
Hotend can be upgraded with a thermocouple sensor and amplifier board, then you can go higher, but I don't know about the limit.
Alternatives to POM:
Ploycarbonate works quite well (I only printed relatively small parts yet) but also releases fumes that are very aggressive and cause burning lung and throat. Ask me how I know. If you can get the print settings right it gives very strong parts.
Nylon: Taulmann has a nice overview of which of their Nylons to use for which parts, and that should be the best alternative for gears.
Iglidur: Igus bearing sells a special filament for bearings
