The system is designed to expose uncertainty, cite manufacturer information, and avoid claims that require physical testing.
Compatibility engine
Five checks shape each verdict.
01
Hotend threshold
The printer’s documented maximum must meet the material family’s minimum nozzle temperature.
02
Bed threshold
The printer’s documented bed maximum must meet the material family’s minimum bed temperature.
03
Enclosure requirement
This conservative screen treats an enclosure as required for ABS, ASA and PC, even where a maker describes it as recommended. A required enclosure is a hard constraint; a recommended enclosure becomes a visible warning. These are screening policies, not universal printing instructions.
04
Abrasive hardware
Filled materials require verified wear-resistant hardware. A standard nozzle receives an upgrade verdict. Known unsuitable gears retain an upgrade warning; unrecorded gear readiness stays conditional. A hardened nozzle alone never verifies the full feed path or an automatic material system.
05
Explicit exclusions
A printer maker’s not-recommended list can override otherwise adequate temperature numbers.
Verdict meanings
A status is a preflight screen—not a promise of print quality.
compatible
Core hardware checks pass. Moisture, tuning, ventilation, and exact formulation still matter.
conditional
The pairing may work, but a soft constraint such as enclosure, moisture, or feed path needs attention.
upgrade needed
Temperature checks pass, but the current hardware is not verified for an abrasive formulation.
not compatible
At least one hard constraint fails or the printer maker explicitly advises against the material.
Interpreting the shortlist
Keep the conditions attached to the answer.
Compatibility uses a family-level temperature screen, not proof that every formulation in that family fits. Passing the lower end of a range does not mean the printer can run every manufacturer profile. Drying references name their source separately because a printing temperature is not a drying instruction.
Unfilled-family printing ranges cite the Prusa material table. The four filled-family ranges are editorial screening ranges: their nozzle-type citation supports wear resistance, not the displayed temperatures. Always compare the exact composite product profile with the printer ceiling, minimum nozzle diameter, gear guidance and feeding-system restrictions. A “wear-resistant nozzle” badge describes only the nozzle, not a fully verified abrasive-filament setup.
All relevant warnings remain visible even when a hard limit fails or an upgrade is required. The dissolvable-support shortlist contains PVA/BVOH and HIPS only; support chemistry, model-material adhesion, and multi-material hardware still need confirmation.
The dryer matcher does not invent a temperature for an unspecified formulation. A reported temperature range that straddles the target is marked conditional, and automatic material systems carry setup-dependent heating and feeding caveats. These checks do not measure chamber uniformity or actual filament temperature.
Optional spool-size screen
Published clearance is a filter, not a physical fit test.
The dryer matcher can compare measured outer diameter, overall width and, where required, the centre-hole opening with cited stock loading limits. A limit is applied only to the documented model and number of spools. For multiple spools, the screen assumes identical dimensions; mixed sizes need a manufacturer-confirmed loading layout.
9 of 13 dryers have at least one documented loading envelope. This does not mean every loading arrangement is known. The remaining 4 records stay unknown; chamber dimensions and spool weight are never converted into individual spool clearance.
Strict “below” and “above” limits remain strict. Minimum dimensions, maximum dimensions and core openings are checked when the source specifies them. An out-of-range fit is removed from the shortlist. “Only documented size matches” also removes unknown fits, without pretending they fail a physical test.
Dimensions alone do not confirm free rotation, feed-through alignment, spool heat tolerance or safe operation. Verify those with the current manual and the actual spool before buying or heating it. Each size result links to its own non-affiliate source and explains any loading restriction.
