PolyMax™ PETG offers better mechanical properties than any other regular PETG making it a good candidate for a wide range of applications.
What is the difference between PolyMax™ PETG and PCTG?
A little bit of Material Science first:
PET is made from terephthalic acid ('TPA') and ethylene glycol ('EG') (CH2OH)2
PCT is made from terephthalic acid ('TPA') and cyclohexanedimethanol (‘CHDM’) C6H10(CH2OH)2
If you react TPA with both EG and CHDM, you get a co-polymer, called PETg or PCTg.
Usually the polymer is called PETg when the major diol is ethylene glycol (>50%) and PCTg when the major diol is CHDM (>50%).
Printing and Drying Settings?
Printing Temperature: 230˚C - 240˚C
Bed Temperature: 70˚C - 80˚C
Printing Speed: 30mm/s - 50mm/s
Fan: 20%
Drying Settings: 65˚C for 6h
(Only if the material has absorbed moisture)
Do I need to use the cooling fan with PolyMax™ PETG?
If you are looking to produce the strongest part (high layer adhesion), we recommend to switch off your part cooling fan.
If you are looking for a high quality surface finish, we recommend to switch on your part cooling fan.
