3.5KG Crystal Clear PETG PRO: finish and uses

The same pigment-free, crystal clear PETG PRO as our 1 kg spool, on a 3.5 kg roll for large prints and production runs. Prints clear and glossy with no haze or yellowing. Made in Indiana, USA.

Printing 3.5KG Crystal Clear PETG PRO

Start with a nozzle temperature of 240–265°C and a bed temperature of 80°C (±10°C). No enclosure is needed. Adjust for your printer, build surface and part geometry.

PETG PRO prints nearly as easily as PLA, with strong layer bonds, nearly zero warping and little to no odor. It performs best when printed dry or from a dry box.

Why a 3.5 kg roll?

A 3.5 kg roll means fewer spool changes on large prints and long production runs. Use a spool holder rated for the larger roll. Prefer the AMS? This color also comes on 1 kg AMS-compatible spools.

PETG PRO or PCTG PRO?

PCTG PRO is our new and improved step up from PETG, with better impact resistance, chemical resistance and surface finish. Start from your PETG PRO settings and adjust. Try Crystal Clear PCTG PRO.

Quality and specifications

Manufactured with laser-based diameter and roundness monitoring. Published diameter and roundness tolerances: ±0.02 mm. Made in Indiana, USA. Supplied as 1.75 mm filament on a 3.5 kg roll.

3.5KG Crystal Clear PETG PRO FAQ

Why does it look satin on the spool?

Depending on the production line, the filament can look satin on the spool. That has no effect on print quality. It prints glossy and clear.

How clear will my prints be?

Our clear PETG has no pigments or dyes and no haze or yellowing. Layer height and print settings affect how much light passes through your parts.

Do I need an enclosure?

No. PETG PRO prints well on open-frame printers.

Does it need drying?

If it has been left out, dry it at 60°C for at least 8 hours. Store it sealed with desiccant between uses.

Can I try it first?

Yes. 50 g PETG PRO sample coils let you check the color and your print settings before buying a full spool.
