# Does filament diameter tolerance matter, and what about 1.75 mm versus 2.85 mm?

1.75 mm and 2.85 mm are which hotend the spool was made for. The supplied comments do not measure a diameter. They joke about a country-of-origin label, count kilograms of PETG and ABS, and mention a dryer.

Diameter tolerance is the question. The comments supplied for it do not measure one. 1.75 mm versus 2.85 mm is which melt zone the spool was drawn for.
## What was actually written

[a Reddit thread in r/3Dprinting](https://www.reddit.com/r/3Dprinting/comments/1trwxjs/): "\"Made in the USA\" There's your problem". "'Made in USA'. I think I found the issue." They are not a caliper reading. The same thread is cited on [filament quality](/answers/filament_quality) and [budget filament](/answers/cheap) for that reason.

[a Reddit thread in r/3Dprinting](https://www.reddit.com/r/3Dprinting/comments/14res8a/) is a stock of PETG and ABS, "total 435 kg," and a wish for a high-temp all-metal hotend. "A filament dryer or dehydrator will help you get your valve there." Drying is [drying](/answers/drying). A hotend that will not melt the loaded spool is a printer limit, not a tolerance.

The comments do not contain them.
## Rows that list two diameters

[SUNLU PLA](/brand/sunlu/pla) lists 1.75 mm and 2.85 mm, with 190–230 °C (374–446 °F) and a bed of 50–70 °C (122–158 °F) from the Open Filament Database. [PolyLite PLA](/brand/polymaker/polylite-pla) lists both diameters, 190–230 °C (374–446 °F), 25–60 °C (77–140 °F), and drying at 55 °C (131 °F) for 6 h. [SUNLU PP](/brand/sunlu/pp) lists both diameters. The product page checked 20 October 2026 is the nozzle source, 210–230 °C (410–446 °F), and the bed is blank. [Eryone PETG](/brand/eryone/petg) is 1.75 mm only in the catalog, nozzle 230–250 °C (446–482 °F) from the product page checked 19 October 2026, bed blank. [PLA](/material/pla), [PETG](/material/petg), and [PP](/material/pp) are the hubs. [SUNLU](/brand/sunlu) and [Polymaker](/brand/polymaker) are the brand indexes.

A diameter that wanders shows up as [flow](/answers/flow) that changes along the spool, and a tight spot shows up as a [clog](/answers/clog).
