3D Printing Ranked

Filament, printer limits and parts

Heat is what kills a printed part.

Choose filament from what your part has to survive, check that your printer, dryer and AMS can handle the spool, and find the replacement part that fits your model.

Every question on this site

13 guides

Each answer comes from the maker's or the standards body's own published documents, listed at the bottom of its page with the date we read them.

Filament

Which filament a part needs, whether your printer can run it, and whether the spool is the right diameter and dry enough.

  • Which filament does this part need?

    Chosen from what the part has to survive — heat, impact, sunlight, moisture — rather than from a material's general reputation. Including why "stronger" is two questions with two different answers.

  • Can my printer actually run it?

    Four independent limits decide this, and the nozzle temperature is often not the one that stops you. How to check each against the filament's datasheet, and what a hardened nozzle does and does not solve.

  • Will a 2.85 mm spool fit my printer?

    Find the spec line that settles 1.75 vs 2.85 mm, see what seven makers list for 19 machines, and check a swapped tool head or hotend before you buy a spool.

  • Will my AMS, oven or dry box get nylon hot enough?

    Compare your spool's drying temperature with the AMS 2 Pro, AMS HT, heated bed, kitchen oven and dry box, with Bambu's settings by material and nylons that need more than 85 °C.

  • Do You Need 90A or 95A TPU?

    Compare Shore hardness, elongation, and stiffness across three TPU grades, then check whether your extruder or Bambu AMS can feed the one you want.

Nozzles and hotend parts

Nozzle sizes, and the replacement parts that have to match your printer model.

  • What layer height can I actually use?

    Your usable range is set by the nozzle fitted, and your slicer may enforce a lower ceiling than the rule you remember. What changing either costs in time, strength and minimum feature size.

  • Which silicone sock fits my Bambu printer?

    Match your printer to the sock Bambu lists for it and the choice in its store listing, including the H2C's two hotends, and read what P2S error 0500-8093 means.

  • Which Hotend Fits Your Bambu Printer?

    Whether a spare X1C, P1, or A1 hotend or nozzle can move to another Bambu printer, straight from Bambu's own compatibility table.

  • Which Nozzle Fits Your Prusa?

    A 0.6 mm nozzle only fits if the thread matches. See which Prusa models use the E3D V6 thread, which use the Nextruder mount, and when you need the adapter.

  • Is My Nozzle Worn Out?

    No manufacturer publishes a nozzle wear limit. See the check some Prusa printers run automatically, and the abrasion, temperature and bore specs to order a replacement.

  • Can Your Plate Handle This Filament?

    Bed-temperature ranges for PLA, PETG, ABS, ASA, PC and TPU across Bambu Lab's plates and Prusa's sheets, plus plate sizes by printer model and what to check before buying a different one.

Five facts that change which spool you buy

Each is taken from a manufacturer's technical datasheet or printer specification, with the test standard named where the source names it.

  • Heat is what usually kills a printed part, not force. In Prusa Polymers' own ISO 75 testing, PLA's heat deflection temperature is 55C, PETG's is 68C, ASA's is 93C at 0.45 MPa, PC Blend's is 113C and PA11 carbon fiber's is 192C. A PLA part left in a parked car or on a sunny windowsill is operating near its limit.

  • "Stronger" is two different questions with two different answers. Measured by the same lab under ISO 527-1 and ISO 179-1, PLA is the stiffer material (2.3 GPa tensile modulus against PETG's 1.5) and yields higher (51 MPa against 47). But in an unnotched Charpy impact test PETG does not break at all, while PLA breaks at 13 kJ/m2. If your part gets dropped or flexed, the stiffer material is the wrong pick.

  • Your printer has four separate limits, and the nozzle temperature is often not the one that stops you. Creality rates the Ender-3 V3 SE at 260C nozzle but only 100C bed. Prusament's ASA datasheet asks for a 110±5C bed. The nozzle could reach ASA's temperature; the bed cannot, so the machine cannot run it as shipped.

  • An all-metal hotend does not mean the printer can handle every filament. The Prusa MK4S has an all-metal hotend rated to 290C and ships with a brass 0.4mm nozzle. Prusament's PA11 Carbon Fiber datasheet states that a hardened nozzle is necessary. Temperature capability and abrasion resistance are independent — carbon fiber, glass fiber, Bronzefill and glow-in-the-dark filaments wear brass regardless of how hot the hotend gets.

  • A bigger nozzle can make a stronger part. In Prusa's own testing, objects printed with a 0.6mm nozzle absorbed up to 25.6% more energy than the same objects at 0.4mm, and 0.25mm objects absorbed 3.6% less. Layer height is capped by nozzle diameter — Prusa's guidance is to stay below 80%, so roughly 0.32mm on a 0.4mm nozzle and 0.48mm on a 0.6mm.

Who this is for

People who own or are about to buy a desktop FDM 3D printer and have a specific part to make or replace: a bracket that has to survive a hot car, a spool that has to fit the AMS, a torn silicone sock. Not professionals with engineering-grade equipment, and not people shopping for a printer.
