Ranked filaments
| Rank | Filament | Material | Nozzle | Bed | Datasheet | Buy |
|---|---|---|---|---|---|---|
| 1 | Prusament · PLA | PLA | 205–225 °C (401–437 °F) | 40–60 °C (104–140 °F) | — | |
Prusament PLA lists a nozzle of 205–225 °C (401–437 °F) and a bed of 40–60 °C (104–140 °F). The OrcaSlicer comment on r/FixMyPrint 1jzuaev uses 220 °C (428 °F), a 45 °C (113 °F) bed, and 40 mm/s on Spectrum Premium PLA. 220 °C (428 °F) and 45 °C (113 °F) sit inside this row. Spectrum Premium PLA is not this catalog row. | ||||||
| 2 | Polymaker · Polylite PLA | PLA | 190–230 °C (374–446 °F) | 25–60 °C (77–140 °F) | Datasheet | |
PolyLite PLA lists 190–230 °C (374–446 °F), a bed of 25–60 °C (77–140 °F), 40–60 mm/s, and drying at 55 °C (131 °F) for 6 h. The same 220 °C (428 °F) and 45 °C (113 °F) comment sits inside this nozzle and bed. The product page lists the fan on. | ||||||
| 3 | Bambu Lab · PLA Basic | PLA | 190–230 °C (374–446 °F) | 35–45 °C (95–113 °F) | Datasheet | |
PLA Basic lists 190–230 °C (374–446 °F) and a bed of 35–45 °C (95–113 °F), with drying at 50 °C (122 °F) for 8 h. 220 °C (428 °F) is inside the nozzle. 45 °C (113 °F) is the top of this bed. The comment was not printed on a Bambu machine. | ||||||
| 4 | Prusament · Matte PETG | PETG | 240–260 °C (464–500 °F) | 70–90 °C (158–194 °F) | — | |
Prusament Matte PETG lists 240–260 °C (464–500 °F) and a bed of 70–90 °C (158–194 °F). Drying on the row is the Prusa material guide, 55 °C (131 °F) for 6 h, not a color-specific sheet. r/prusa3d 16cnyzd asks about this look. Replies say it seems less flexible and that they cannot prove it. | ||||||

One product row is one nozzle range. A second color of that product can still want its own flow and temperature inside that range.
Same gcode, two colors
r/FixMyPrint 1jzuaev prints Spectrum Premium PLA, white then black, on an Ender 3 Pro. The score-21 reply says different colors are different material and that each color needs a profile. A score-3 reply splits light shades from dark shades and says only a few colors needed their own third profile. Another score-3 reply is at 220 °C (428 °F), a 45 °C (113 °F) bed, and 40 mm/s. Those three numbers are that comment. They sit inside Prusament PLA at 205–225 °C (401–437 °F) and 40–60 °C (104–140 °F), and inside PolyLite PLA at 190–230 °C (374–446 °F) and 25–60 °C (77–140 °F). PLA Basic includes 220 °C (428 °F), and 45 °C (113 °F) is the top of its 35–45 °C (95–113 °F) bed. Spectrum Premium PLA is not a catalog id. Flow for a single color is on flow calibration. PLA nozzle choices are on PLA temperatures and nozzle temperature in general.
Matte black PETG
r/prusa3d 16cnyzd asks how Prusament Matte Black PETG compares with Galaxy Black and Jet Black. A score-3 reply likes the look, thinks it is less flexible, and says they cannot prove it. Another says a different maker's matte black hides seams. Prusament Matte PETG lists 240–260 °C (464–500 °F) and a bed of 70–90 °C (158–194 °F). This page does not add a stiffness number. PETG is the material page.
Threads that are not pigment
r/BambuLab 158cktx is white PLA stuck after a push at 250 °C (482 °F). The leading reply heats a hex key, pushes it into the filament, and pulls. That is a clog, not a white-pigment temperature.
r/BambuLab 17tpo7j is black PLA marking other colors. The score-37 reply says the purge is too small.
r/FixMyPrint zxnw8h is Hatchbox black PETG. The replies say the nozzle is too high. Hatchbox PETG lists 230–260 °C (446–500 °F) and a bed of 70–90 °C (158–194 °F), and drying is empty on that row. Prusament and Polymaker are the brand indexes for the ranked spools.
Pros and cons
Pros
- The profile-per-color line is the highest-scored reply on the thread that actually compares two colors of one PLA.
- The other four threads stay labeled as a clog, a purge, a matte-PETG impression, and a first layer.
Cons
- No ranked row lists a different nozzle for black and for white. This page does not invent that split.
- The 220 °C (428 °F), 45 °C (113 °F), and 40 mm/s figures are one commenter's Spectrum settings on an Ender 3 Pro. They are not a Spectrum datasheet, and Spectrum Premium PLA is not a ranked id.
Printer considerations
- Split light and dark shades into two profiles when one profile misbehaves. That split is a score-3 reply on r/FixMyPrint 1jzuaev, not a catalog field.
- A color change in an AMS still needs a purge. Black marks on another color, in r/BambuLab 17tpo7j, are leftover black in the hotend.
- A first layer that will not stick is a Z offset until the color is ruled in. r/FixMyPrint zxnw8h is Hatchbox black PETG, and the replies raise the bed or lower Z.
What the community says
r/FixMyPrint 1jzuaev is the same gcode on an Ender 3 Pro with a Micro Swiss hotend. White Spectrum Premium PLA was dialed in, and black Spectrum Premium PLA underextruded. The score-21 reply says different colors are different material and that each one needs a profile. A score-3 reply keeps two profiles, light shades and dark shades, and says only a couple of colors needed a third. Another score-3 reply is printing at 220 °C (428 °F), a 45 °C (113 °F) bed, and 40 mm/s in OrcaSlicer. r/prusa3d 16cnyzd asks about Prusament Matte Black PETG. A score-3 reply likes the look and thinks it is less flexible than other PETG, and says they cannot prove it. Another score-3 reply says a matte black from a different maker hides vertical seams. r/BambuLab 158cktx is white PLA stuck in a hotend after a heat to 250 °C (482 °F) failed to push it out. The leading reply is a heated hex key used as a pull, which is a clog method. r/BambuLab 17tpo7j is black PLA marking other colors on an X1C with an AMS. The score-37 reply says the black purge is too low. r/FixMyPrint zxnw8h is Hatchbox black PETG on painter's tape. The replies say the nozzle is too far off the bed.

Questions
Should black and white share one slicer profile?
The score-21 reply says no. Set a profile per color. A lower reply on the same thread keeps one profile for light shades and one for dark shades. The catalog still stores one nozzle range per product.
Why does black PLA mark the next color?
On r/BambuLab 17tpo7j the score-37 reply says the purge of the black is too small, so black left in the hotend mixes into the next color. That thread does not treat black as a different polymer.
