We released our TECH-G High Strength PETG today in Clear. As this group likes specifications, I’ve attached the Lab results of Tensile and IZod. We had released this to a few sites in March of this year to get feedback and have now finalized the material. TECH-G comes on 1kg spools of 1kg weight. Currently “Clear” only, but we will look for feedback on color. As a note, we are sensitive as to how colorants effect strength and print settings. TECH-G prints at 235C to 240C. Because TECH-G is a Co-Polyester, it works well with print beds of PEI sheets and clean glass heated to 65C or Glass coated with a wipe of 50% PVA/Water heated to 45C. A tip for G+ users: We worked hard to pin down the melt viscosity such that those with fast printers and Volcano type nozzles can increase print speed by increasing print temp slightly. Setting are different from printer to printer but we have printed at 80mm/s at 260C on med size parts with a .5mm nozzle
How does this compare to the bridge nylon?
I really need to get some bigger nozzles.
@Eric_Davies Bridge is a Nylon Polymer and has 4,800 Tensile with 200% Elongation. TECH-G is a very stiff material like PLA but more give so less brittle than PLA’s.
@Ashley_Webster TECH-G has excellent layer bonding with over stressed parts cracking along and across layers. TECH-G is a pure resin or made from virgin pellets. PETG from regrind (Ground up from recycled packaging and usually opaque or a yellowish clear) will always have bonding issues. This is because minerals or other lubricants are used in Injection molding or Blow molding and can not be removed from reground PETG.
While we’re on the subject of PET, is there one that will print well, without the heated bed?
What’s the glass transition temp? Same as typical PETG?
@Michael_New Tg of TECH-G is around 75C.
