# What filament prints clear/transparent?

Translucent PETG and PCTG are the clear-filament rows in this catalog, and a gap-free print is the process people describe, with no optical transmission percent stored.

Translucent PETG and PCTG are the clear products this catalog can name. PC is the other material in the editorial summary. None of them stores a transmission percent. A clear look, in the comments, comes from fewer air gaps.

## Catalog rows

[Bambu PETG Translucent](/brand/bambu-lab/petg-translucent) lists 220–250 °C (428–482 °F), a bed of 70–90 °C (158–194 °F), drying at 65 °C (149 °F) for 8 h, and speed up to 220 mm/s. [ELEGOO PETG Translucent](/brand/elegoo/petg-translucent) lists 230–260 °C (446–500 °F) and 65–75 °C (149–167 °F), with a drying temperature of 65 °C (149 °F) and no hours. [extrudr PCTG](/brand/extrudr/pctg) lists 230–260 °C (446–500 °F) and 70–90 °C (158–194 °F). [Bambu PC](/brand/bambu-lab/pc) lists 260–300 °C (500–572 °F), 100–120 °C (212–248 °F), and drying at 80 °C (176 °F) for 8 h. [PETG](/material/petg), [PCTG](/material/pctg), and [PC](/material/pc) are the hubs. [How to print PC](/answers/pc) is the polycarbonate process. [PETG printing](/answers/petg_print) is the ordinary PETG process.

## What the comments change, and what they do not

A comment on r/3Dprinting 113p9gp says the clearer part was printed more slowly, and to print hot, slow, and wide, with over-extrusion. A second comment on that thread guesses at crystal structure and cooling. This page does not adopt the guess.

A comment on r/FixMyPrint 1ob77w8 points at a CNC Kitchen video about reducing air gaps, and another comment on that thread lists a smooth plate, 20–50 mm/s, 100% rectilinear infill aligned with the skins, and slight over-extrusion for clear PETG. The 20–50 mm/s figure stays on that comment. Bambu's sheet still says up to 220 mm/s. The comment also mentions a Bambu article. The URL was not in the excerpt, so it is not linked here. A smooth plate is the [build plate](/answers/plate) topic. PETG on smooth PEI still has the weld warning on the bed-adhesion guide.

r/3Dprinting 1ds8ap2, r/3Dprinting se46uc, and r/BambuLab 1mn27m5 are in the bank. The supplied excerpts do not include a clarity measurement from them.

## What "clear" does not mean here

The summary says true clarity needs post-processing. These datasheets do not list a sanding, coating, or annealing step, so this page does not invent one. The product name translucent is not a haze number.

## What the community says

The editorial summary says clear prints need PETG or PC, printed hot, slow, with thick layers and 100% infill or no gaps, and that true clarity needs post-processing. The bank's recommended materials are PETG and PCTG. PCTG is in the catalog. A comment on r/3Dprinting 113p9gp says hot, slow, and wide, with over-extrusion. A comment on r/FixMyPrint 1ob77w8 names 20–50 mm/s, a smooth plate, 100% rectilinear infill, and slight over-extrusion for clear PETG, and mentions a Bambu article without a URL in the excerpt. Bambu PETG Translucent's own sheet lists speed up to 220 mm/s, which is a different number and stays on that row.
