Nylon Filament Drying and Print Temperature: 240–260°C Settings for Tronxy White 1.75mm
This answer-first guide for the Tronxy White Nylon 1.75mm spool sets out the drying-first workflow: why nylon must be dry before it prints, the 240–260°C nozzle range from the listing, the heated-bed requirement, the all-metal hotend check, the chamber temperature for anti-warp, and a temp-tower routine. General studio practice is labelled separately from the listing facts, and the companion warping-and-adhesion guide covers the moisture symptoms, the diagnostic table and the bed-prep fixes.
Answer first: dry it, then print it hot in an enclosure
The Tronxy White Nylon Filament is a 1.75mm, 1kg spool of white PA nylon with a tolerance of ±0.05mm, priced at $47.99 under SKU HC-1KG-PA-White. The listing recommends a print temperature of 240–260°C and notes that it is better with a heated bed. The listing describes the spool as tangle-free, ROHS and ISO9001 certified, and strong and flexible for wear-resistant parts.
The working order is dry first, then hot. General studio practice dries the spool at 70–80°C for 6–12 hours before the first print, and for an opened spool a minimum of 12 hours at 80°C, or 24 hours if the spool has been open for a while. The nozzle runs at 240–260°C, the bed at 80–110°C, and an enclosed chamber at 55–60°C to keep the part from warping. The hotend must be all-metal, because a PTFE-lined tube cannot handle the 240°C range.
The fastest path to a clean nylon print is to confirm the hotend, dry the spool, heat the bed, then run a temp tower. Do not print nylon straight from the bag without drying, and do not run it on a PTFE hotend. The companion warping-and-adhesion guide covers the moisture symptoms, the diagnostic table and the PEI bed-prep fixes; this guide covers the drying workflow, the temperature bands and the hotend check.
Why nylon is a dry-first filament
Nylon is one of the most hygroscopic filaments on the bench, which means it pulls moisture out of the air the moment the bag opens. The moisture does not sit on the surface; it absorbs into the plastic, and when the nozzle heats the filament, the water turns to steam and bubbles through the melt. The listing FAQ says to store the spool in a cool, dry, sealed bag, and the ecosystem practice is to dry the spool before every print session if it has been open.
The drying workflow before the first print
| Spool state | Drying cycle (general practice) | Why |
|---|---|---|
| Freshly opened bag | 70–80°C for 6–12 hours | Even a fresh spool absorbs moisture on the bench |
| Opened for several days | 80°C for 12 hours minimum | The open spool has pulled ambient humidity |
| Opened for weeks in a damp room | 80°C for 24 hours | The moisture has penetrated the core of the spool |
| Spool showing bubbles or popping | 80°C for 12 hours, then test | The moisture symptoms are the diagnosis key |
The seller has not published an official drying temperature, so the 70–80°C band is general practice. The listing's store-cool-and-dry advice is the storage rule, and the drying cycle is the print-prep rule. A spool that has been dried and then left open re-absorbs moisture within hours, so the dry-box storage is covered in the companion guide.
The hotend check: all-metal is required
Nylon prints at 240–260°C, and a PTFE-lined hotend tube softens and off-gasses above 240°C. General studio practice confirms the hotend is all-metal before the first nylon print, because a PTFE tube that degrades at 240°C can release fumes and clog the nozzle.
The hotend compatibility check
- Check the hotend spec. Look for an all-metal hotend, or a hotend rated for 260°C and above. Most modern desktop printers ship with an all-metal hotend, but older Bowden setups often have a PTFE liner.
- Confirm the maximum nozzle temperature. The printer's menu should go to 260°C; if it caps at 240°C, the hotend may be PTFE-lined and needs an upgrade before nylon.
- Inspect the nozzle for wear. Nylon is wear-resistant, so a brass nozzle that has run many PLA prints may be worn; a hardened steel nozzle is the general-practice upgrade for nylon.
- Run a cold pull. Heat the nozzle to 250°C, push a cleaning filament through, and pull it out cold; the cleaning filament clears the old plastic before the nylon load.
The seller has not published a hotend compatibility list, so the all-metal check is general practice. A printer that cannot reach 260°C is not ready for nylon, and the filament comparison guide covers the lower-temperature alternatives.
The temperature bands: nozzle, bed, chamber
Nylon needs three temperatures working together: the nozzle melts the filament, the bed keeps the first layer from cooling too fast, and the chamber keeps the whole part from warping. General studio practice splits the settings into bands so the printer can hold each one steadily.
| Setting | General-practice band | Why |
|---|---|---|
| Nozzle temperature | 240–260°C | The listing range; the upper end flows cleaner, the lower end reduces stringing |
| Bed temperature | 80–110°C | A heated bed is the listing note; 90°C is the general-practice starting point |
| Chamber temperature | 55–60°C | An enclosed chamber keeps the part warm and reduces warping |
| Part fan | Off or low | Nylon does not want the fan; a fan cools the part too fast and causes warping |
| Print speed | 30–60mm/s | General-practice slow band; nylon needs time to bond layer to layer |
General practice: start at 250°C nozzle, 90°C bed, 55°C chamber, and the fan off. Run a temp tower between 240 and 260°C, and pick the band where the walls are clean and the layers bond without warping. The seller has not published a chamber-temperature spec, so the 55–60°C band is general practice.
The temp tower for nylon
A nylon temp tower works the same way as a PLA tower, but the temperature range is higher and the chamber is on. General studio practice prints the tower at 0.2mm layers, with the fan off, and the bed at 90°C, so the tower stays bonded while the nozzle steps down.
The tower step order
- Slice a temp tower model. Set the tower to drop 5°C per band from 260°C down to 240°C.
- Run the chamber at 55°C. The chamber keeps the tower from warping as it grows.
- Print the tower at 30–40mm/s. Slow is safe for the test; the wall quality matters more than the speed.
- Inspect each band. Look for layer adhesion, stringing, and a rough or bubbly surface. A bubbly band means the spool is not dry; a clean band means the temperature is right.
- Lock the nozzle temperature and move to the bed. Do not change two settings at once; the temperature decision comes before the bed decision.
General practice: a bubbly tower at every band means the spool needs another drying cycle, not a higher temperature. The seller has not published a temp-tower profile, so the routine is general practice.
Bed prep and first-layer adhesion for nylon
Nylon sticks best to a PEI sheet, and a clean PEI surface with a light coat of adhesive gives the first layer something to grip. General studio practice uses a PEI sheet on a 90°C bed, with a thin layer of adhesive for the first print, then relies on the PEI surface alone for subsequent prints.
| Bed element | General-practice setup | Why |
|---|---|---|
| Bed surface | PEI sheet | PEI gives nylon a grip that releases when the part cools |
| Bed temperature | 80–110°C | A warm bed keeps the first layer from cooling too fast |
| Adhesive | Thin coat for the first print | A light glue stick or slurry helps the first layer bond |
| First-layer speed | 20–30mm/s | A slow first layer lays a controlled bead |
| Part fan | Off | Nylon does not want the fan; the chamber does the warming |
General practice: a clean PEI sheet at 90°C, with a thin adhesive coat on the first print, bonds the first layer without warping. The companion warping-and-adhesion guide covers the bed-prep fixes when the first layer lifts or the corners curl.
Calibration checklist before the first nylon job
Before you run a real part on the Tronxy White Nylon, run this checklist. Each item is a general-practice step that catches the most common first-job failures, and none of them is a listing spec — the seller has not published a machine profile.
- Dry the spool. 70–80°C for 6–12 hours, or 80°C for 12 hours if the spool has been open.
- Confirm the all-metal hotend. The printer must reach 260°C; a PTFE liner is not compatible.
- Measure the filament diameter with calipers. The listing says 1.75mm, ±0.05mm. Verify at three points and set the slicer to the measured average.
- Set the bed to 90°C and the chamber to 55°C. The chamber keeps the part warm; the bed bonds the first layer.
- Run the temp tower. Pick the cleanest band between 240 and 260°C.
- Turn the part fan off. Nylon does not want the fan; a fan causes warping.
- Print a single-layer first-layer test. A smooth, even line with no gaps means the bed is level and the nozzle height is right.
- Record the settings. Write the nozzle, bed, chamber and drying cycle on the spool label; the next build starts from a known good state.
Common beginner mistakes on white nylon
A few settings catch out most new nylon users. Each row pairs the mistake with the symptom and the fix, and the symptom is what you will see on the bench.
| Mistake | Symptom on the print | Fix and prevention |
|---|---|---|
| Printing straight from the bag without drying | Bubbles, popping, rough surface | Dry at 70–80°C for 6–12 hours before the first print |
| Running a PTFE hotend at 250°C | Off-gassing, clogging, fumes | Upgrade to an all-metal hotend before nylon |
| Part fan on at 100% | Warping corners, weak layer adhesion | Turn the fan off; the chamber does the warming |
| No chamber, open bench | Warping corners curling off the bed | Enclose the printer or run a chamber at 55–60°C |
| Bed at 60°C like PLA | First layer lifts, corners curl | Raise the bed to 80–110°C; nylon wants a warm bed |
| Printing at 80mm/s like PLA | Weak layer adhesion, rough walls | Slow to 30–60mm/s; nylon needs time to bond |
| Leaving the spool open after drying | Re-absorbs moisture within hours | Store in a dry box below 15% RH; the companion guide covers the storage |
Starter projects on the Tronxy White Nylon
After the calibration checklist, the right starter parts teach the settings without wasting plastic. General practice: start small, flat and layer-sensitive, so each test exposes one setting.
| Project | What it tests | Next step when it prints clean |
|---|---|---|
| Temp tower | Nozzle band, layer adhesion, bubbling | Lock the temperature; move to the bed prep |
| First-layer square | Bed level and nozzle height | Move to a small functional bracket |
| Small gear or bushing | Wear-resistant part in the right material | Print a larger functional wear part |
| Living hinge | Nylon flexibility and layer bonding | Tune the wall count and print a flex part |
| Calibration cube | Dimensional accuracy, ±0.05mm tolerance | Print a functional bracket or tool holder |
General practice: a clean white nylon gear at 250°C, 90°C bed, 55°C chamber, fan off, and a dried spool means the profile is ready for larger wear parts. The seller has not published a profile, so the settings on your spool label are the working record.
Flow, layer height and line width after the temp tower
Once the temp tower locks the nozzle band, the next calibration step is the extrusion flow, because the ±0.05mm diameter tolerance means the filament is consistent, but the slicer's default flow may still under- or over-extrude. General studio practice measures the wall thickness of a 100% infill cube with calipers and compares it to the sliced wall thickness, then adjusts the flow multiplier so the measured wall matches the sliced wall to within 0.1mm.
The layer-height and line-width working range
| Setting | General-practice range | What it controls |
|---|---|---|
| Layer height | 0.1–0.3mm | Detail vs speed; 0.2mm is the general-practice default |
| Line width | 0.4–0.6mm | The wall bead; a 0.4mm nozzle with a 0.45mm line width is a clean default |
| Wall count | 3–4 walls | The structural strength of the part; 3 walls is the general-practice minimum |
| Infill density | 20–40% for functional parts | Nylon is strong, so the infill can stay lower than on weaker materials |
| Flow multiplier | 95–105% after calibration | The amount of plastic the nozzle lays; calibrate with a measured wall |
General practice: a 0.2mm layer with a 0.45mm line width on a 0.4mm nozzle lays a clean wall, and the flow multiplier should be within 95–105% after the wall measurement. The seller has not published a layer-height or line-width profile, so these are general-practice starting points.
What the Tronxy white nylon competes with on the bench
The listing describes the Tronxy White Nylon as strong and flexible, wear-resistant, and tangle-free, with ROHS and ISO9001 certification. General studio practice compares nylon on the temperature, strength and moisture axes rather than the brand name, because the drying workflow matters more than the label. The material comparison guide covers the nylon versus PETG versus TPU differences, and the roundup compares the Tronxy spool against the common white nylon competitors on the market.
The working takeaway is that a clean white nylon gear at 250°C, 90°C bed, 55°C chamber, fan off, and a dried spool beats a noisy, bubbly print at any brand. The seller has not published a material-grade comparison, so the brand choices are covered in the comparison guides rather than here. Nylon's tensile strength of 45–85 MPa and its heat resistance up to around 120°C are the reasons it suits gears, bushings and living hinges rather than display models.
What to do when the first layer does not stick
The first layer is where most nylon jobs fail, and the fix is almost always a small adjustment rather than a new spool. General studio practice works the first-layer adhesion in a fixed order: bed level first, nozzle height second, bed temperature third, and chamber last. A clean PEI sheet at 90°C with a thin adhesive coat bonds the first layer; a dirty PEI surface lifts it, and a cold bed lets it curl.
The Bottom Line
The bench verdict: the Tronxy White Nylon spool, $47.99 under SKU HC-1KG-PA-White, prints cleanly at 250°C nozzle, 90°C bed, 55°C chamber, fan off, after a 70–80°C drying cycle of 6–12 hours. Start by drying the spool, confirm the all-metal hotend, set the bed and chamber, then run a temp tower. The listing's 240–260°C range is the envelope, the 80–110°C bed is the working band, and the seller has not published an official drying temperature or a machine profile. The companion warping-and-adhesion guide covers the moisture symptoms, the diagnostic table and the PEI bed-prep fixes.
Frequently Asked Questions
What nozzle temperature should I use for Tronxy white nylon?
The listing recommends 240–260°C. General studio practice starts at 250°C, with a 90°C bed and a 55°C chamber, then runs a temp tower between 240 and 260°C to pick the cleanest band. The upper end flows cleaner, the lower end reduces stringing.
Do I need to dry nylon before printing?
Yes. General studio practice dries the spool at 70–80°C for 6–12 hours before the first print, and for an opened spool a minimum of 12 hours at 80°C, or 24 hours if the spool has been open for weeks. Nylon is one of the most hygroscopic filaments on the bench, and moisture shows up as bubbles, popping and rough surfaces.
Does nylon need an all-metal hotend?
Yes. General studio practice confirms the hotend is all-metal before the first nylon print, because a PTFE-lined tube softens and off-gasses above 240°C. The printer must reach 260°C in the temperature menu; if it caps at 240°C, the hotend may need an upgrade.
What bed temperature works for nylon?
The listing says nylon is better with a heated bed. General studio practice runs the bed at 80–110°C, with 90°C as the starting point. A PEI sheet on the warm bed gives the first layer something to grip, and a thin adhesive coat helps on the first print.
Should I run the part cooling fan for nylon?
No. General studio practice turns the part fan off for nylon, because a fan cools the part too fast and causes warping. The chamber at 55–60°C keeps the part warm instead, and the layers bond as they cool slowly.
What print speed works for nylon?
General studio practice runs nylon at 30–60mm/s. Nylon needs time to bond layer to layer, so a slow wall and a controlled first layer matter more than a fast infill. The first layer stays at 20–30mm/s even after the rest of the profile speeds up.
Why is my nylon print bubbling and popping?
Bubbles and popping are moisture signs, not temperature problems. General studio practice: dry the spool at 80°C for 12 hours, then test-extrude. A bubbly tower at every band means the spool needs another drying cycle, not a higher nozzle temperature.
What diameter tolerance does the Tronxy white nylon have?
The listing says 1.75mm with a tolerance of ±0.05mm. General practice: verify with calipers at three points along the spool, and set the slicer to the measured average. A consistent diameter keeps the extrusion flow even and the walls clean.
What is the Tronxy white nylon best for?
The listing describes the spool as strong and flexible, wear-resistant, and tangle-free. General studio practice: nylon suits gears, bushings, living hinges and functional wear parts, where the material's tensile strength of 45–85 MPa and its heat resistance matter. The material comparison guide covers nylon versus PETG versus TPU.
Which printers can run the Tronxy white nylon?
The listing does not publish a model-by-model compatibility list, but the working requirement is an all-metal hotend that reaches 260°C, a heated bed that reaches 90°C, and ideally an enclosed chamber. Confirm your printer takes 1.75mm filament and reaches the temperature bands before ordering.
