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 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 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 lists 230–260 °C (446–500 °F) and 70–90 °C (158–194 °F). Bambu 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, PCTG, and PC are the hubs. How to print PC is the polycarbonate process. PETG printing 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 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.
Pros and cons
Pros
- The ranked clear rows exist: two translucent PETG products and a PCTG product with a datasheet.
- Speed and infill advice stays labeled as a comment, next to the catalog speeds that differ from it.
Cons
- No row stores an optical transmission percent. Clear in the product name is not a measured haze value.
- True clarity needing post-processing is the editorial summary. These sheets do not list a post-process.
Printer considerations
- A comment on r/FixMyPrint 1ob77w8 says clear PETG wants a smooth build plate, very slow speeds stated as 20–50 mm/s, 100% rectilinear infill aligned with the top and bottom, and slight over-extrusion. Those are that comment's settings. They are not written onto the PETG rows.
- The same comment mentions a Bambu article. The URL is not in the supplied text, so this page does not invent one.
- A comment on r/3Dprinting 113p9gp says to print hot, slow, and wide, and to over-extrude, and guesses at a crystal structure. The guess is not adopted as a material fact.
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.

Questions
Is 20–50 mm/s the catalog speed for clear PETG?
No. That range is a comment on r/FixMyPrint 1ob77w8. Bambu PETG Translucent lists print speed up to 220 mm/s, a nozzle of 220–250 °C (428–482 °F), and a bed of 70–90 °C (158–194 °F). ELEGOO PETG Translucent lists 230–260 °C (446–500 °F) and 65–75 °C (149–167 °F) and does not list a speed.
Is PCTG in the catalog?
Yes. extrudr PCTG lists a nozzle of 230–260 °C (446–500 °F) and a bed of 70–90 °C (158–194 °F) on its technical data sheet. The row does not store a clarity percent, a drying time, or a post-process.
