HobbyKing 3D Printer Filament 1.75mm POM 1KG Spool (Black)
HobbyKing have come out with a huge new range of 3D Printer Filaments at prices that will have you printing all day and all night.
The range covers PLA, ABS, Flexible, Color Changing, Luminous, Nylon, Polycarbonate, Acetal (POM), Metal Composite and even a water soluble filament for printing molds. So there is a filament for every project you have in mind. HobbyKing filaments have a stable melting point, good round shape and most importantly a 0.01mm uniform diameter tolerance for a consistent flow rate.
POM or Polyoxymethylene is also know by other names such as acetal, polyacetal, polyformaldehyde.
It is a great product if you have repeated use and need high stiffness, low friction or high impact resistance and can make products like ball bearings, gears or lock systems.
3D printing is a fun and exciting hobby with a wide range of uses from prototyping parts to making toys for the kids. Picking the right filament for your application is very important.

After long and thorough tinkering I'm beginning to get usable results.
1. The warping is brutal, and it is very strong. First of all, you need to have good first layer adhesion.
What works: a sheet of Garolite (phenolic fiber board) bonded to 2mm alu, clamped to the bed. Heat up to 90°C and apply thin ABS slurry. This gives a very rough, velvet-like surface that bonds VERY well.
2. Use a wide brim. I use 8 lines and 2-3 layers. Bed temp 110-120°C. (Any higher and the ABS slurry goes soft).
3. Temperatures and speeds. You need to experiment A LOT, depends heavily on hotend and ambient temps. In theory it can be printed at 180°C but I never got good layer bonding under 220. You want to get as low as you can to minimize warping.
4. Try to avoid drafts and uneven cooling. A heated build chamber is a good idea, every degree helps.POM is well known to be not so easy to print, and it is! I use it on a ABS "bed" because i bought it to be part of multimaterials object, my idea is to use it mixed with PC, I will try in the nect day this mix taht in my personal opinion is the best choice for having ultra strong result. I read a discussion on POM and people had good results printing them on cotton and on cardboard for having a good first layer bond. Temperature used by me nozzle 220 bed 130.
