How to Print ABS Without Warping: Temperature, Enclosure and Bed Settings for Tronxy 1.75mm
This answer-first guide for the Tronxy Black ABS 1.75mm spool sets out the warping-free workflow: keep the chamber warm, run the bed hot, turn the fan off, and slow the first layer. General studio practice is labelled separately from the listing facts, and the companion troubleshooting guide covers the warping diagnosis, the stringing and blob fixes, the fumes and ventilation notes, and the acetone vapor smoothing workflow.
Answer first: warm the chamber, heat the bed, turn the fan off
The Tronxy Black ABS Filament is a 1.75mm, 1kg spool with a dimensional accuracy of ±0.02mm per the spec table, priced at $43.99 under SKU CXY08.01.0028. The spec table lists a printing temperature of 220–240°C, a heated bed of 80–120°C, and a spool length of 395m. The features recommendation runs the nozzle at 230–270°C, and the listing header quotes ±0.03mm. The listing describes the spool as low-odor, low-warp and zero-bubbles, with a glossy finish and the ability to be smoothed with acetone after printing.
The warping-free workflow is to warm the chamber, heat the bed, and turn the fan off. General studio practice: the chamber holds at 40–60°C, the bed runs at 100–110°C, the fan stays off or at most 20–30%, and the first layer runs the nozzle 5–10°C hotter than the rest of the print. The listing's 80–120°C bed band is the envelope; the warping practice runs the upper end at 100–110°C. A clean bed and a light adhesion spray keep the first layer bonded, and a slow first layer at 30–40mm/s gives the plastic time to grip.
The fastest path to a warp-free ABS print is to warm the enclosure to 50°C, set the bed to 105°C, turn the fan off, and run a one-wall calibration cube on a clean adhesion-sprayed plate. Do not print ABS on an open bed without a warm chamber, and do not run the part fan on the first layers. The companion troubleshooting guide covers the warping diagnosis, the stringing and blob fixes, the fumes and ventilation notes, and the acetone vapor smoothing workflow; this guide covers the temperature, the enclosure, the bed prep and the first-layer tune.
Why ABS warps and how the warm chamber stops it
ABS warps because the outer layers cool faster than the inner layers, and the shrinkage pulls the corners off the bed. General studio practice: the fix is to keep the whole print warm from the outside, so the layers cool at the same rate and the corners stay flat. An enclosure that holds 40–60°C around the part does this, and a bed that runs at 100–110°C keeps the bottom layer from contracting while the print builds.
The temperature bands that stop the corners lifting
| Setting | General-practice band | Why it matters |
|---|---|---|
| Nozzle temperature | 220–260°C | The listing's 220–240°C spec and 230–270°C recommendation bracket this band |
| Heated bed | 100–110°C | The listing's 80–120°C band; the upper end stops the bottom layer contracting |
| Enclosure chamber | 40–60°C | Warm air around the part cools the layers evenly and stops the corners lifting |
| Part fan | Off, or at most 20–30% | A fan chills the outer layer and pulls the corner off the bed |
| First-layer nozzle | +5–10°C hotter | A hotter first layer flows flatter and grips the bed better |
| Print speed | 30–60mm/s | First layer 30–40mm/s; the rest of the print 40–60mm/s |
The seller has not published an ABS temperature profile, so the bands are general practice. The companion troubleshooting guide covers the warping diagnosis, the stringing and blob fixes, and the acetone vapor smoothing workflow. This table sets the expectation that the enclosure temperature is the single most important warping control.
The bed prep that keeps the first layer bonded
A warm chamber and a hot bed are not enough if the bed surface is dirty. General studio practice: a clean glass plate at 105°C with a light adhesion spray bonds the first layer, and a greasy or dusty plate lets the corners lift. The listing says the spool prints on a heated bed, and the tips note that ABS needs a heated bed to prevent warping. The adhesion spray is a general-practice accessory, not a listing item.
The bed prep sequence before the first ABS print
- Clean the glass plate with isopropyl. A clean bed gives the first layer a fresh grip.
- Wipe a light coat of adhesion spray. A 3DLAC-style spray is a general-practice adhesion aid; the seller has not published a recommendation.
- Preheat the bed to 105°C and the chamber to 50°C. The bed reaches the working temperature before the first layer starts.
- Level the bed and set the Z-offset. The first layer squashes flat without digging into the plate.
- Run the first layer at 30–40mm/s. A slow first layer lets the plastic flow and grip.
General practice: a clean, adhesion-sprayed plate at 105°C holds the first layer while the chamber stays at 50°C. The seller has not published a bed-prep sequence, so the steps are general practice. The companion troubleshooting guide covers the warping diagnosis when the corners still lift after the prep.
The first-layer tune: hotter nozzle, slower speed, fan off
The first layer is where the warp starts, and the fix is to run the first layer a little hotter, a little slower, and with the fan off. General studio practice: the first-layer nozzle runs 5–10°C hotter than the rest of the print, the first-layer speed drops to 30–40mm/s, and the fan stays off for the first 3–5 layers. A hotter first layer flows flatter and grips the bed, and a slow first layer gives the plastic time to bond before the next layer lands.
| First-layer setting | General-practice band | Why |
|---|---|---|
| Nozzle temperature | +5–10°C hotter than the rest | A hotter first layer flows flatter and grips the bed |
| Print speed | 30–40mm/s | A slow first layer gives the plastic time to bond |
| Part fan | Off for the first 3–5 layers | A fan chills the first layer and pulls the corner off the bed |
| Line width | Slightly wider than the rest | A wider first line squashes flat and grips the bed |
| Layer height | 0.2–0.3mm | A thicker first layer squashes into a flat bond |
General practice: a first layer at 250°C, 105°C bed, 35mm/s, fan off, reads as a flat, bonded sheet on a clean glass plate. The seller has not published a first-layer profile, so the bands are general practice. The companion troubleshooting guide covers the warping diagnosis when the first layer still lifts.
Calibration checklist before the first ABS print
Before you run a real ABS part on the Tronxy Black ABS spool, run this checklist. Each item is a general-practice step that catches the most common first-print failures, and none of them is a listing spec — the seller has not published an ABS profile.
- Warm the enclosure to 50°C. The chamber holds the part at a working temperature.
- Set the bed to 105°C and the nozzle to 245°C. The listing's bands; the starting point for the calibration cube.
- Clean the glass plate and wipe a light adhesion spray. A clean, sprayed plate holds the first layer.
- Level the bed and set the Z-offset. The first layer squashes flat without digging.
- Turn the part fan off. A fan chills the outer layer and pulls the corner off the bed.
- Slice a one-wall calibration cube. 0.2mm layers, 40mm/s, 245°C nozzle, 105°C bed, 50°C chamber.
- Print the cube and watch the corners. Flat corners mean the profile is ready; lifting corners mean the bed needs a wipe or the chamber needs to be warmer.
- Record the settings. Write the nozzle, bed, chamber, fan and speed on the spool label; the next ABS print starts from a known good state.
Common beginner mistakes on black ABS
A few settings catch out most new ABS 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 ABS on an open bed | Corners lift, part warps | Warm the enclosure to 50°C before the print |
| Running the part fan at 50% | Corners curl, layer separation | Turn the fan off, or at most 20–30% |
| Running the bed at 80°C | Bottom layer contracts, corners lift | Raise the bed to 100–110°C |
| Printing the first layer at 60mm/s | First layer skips, part detaches | Slow the first layer to 30–40mm/s |
| Running the first layer at 220°C | First layer does not flow, weak bond | Run the first layer 5–10°C hotter |
| Skipping the bed clean | First layer peels off in strips | Clean the glass with isopropyl before each print |
| Changing temperature and fan together | You cannot tell which fix worked | One setting at a time; record each test cube |
Starter projects on the Tronxy Black ABS
After the calibration checklist, the right starter parts teach the warping-free workflow without wasting plastic. General practice: start small and hollow, so each test exposes one setting.
| Project | What it tests | Next step when it prints flat |
|---|---|---|
| One-wall calibration cube | Warping, bed prep, chamber temp | Lock the profile; move to a small functional part |
| Small enclosure cover | Layer adhesion on a flat part | Print a larger functional cover |
| Bracket or clip | Tensile strength and bed adhesion | Print a load-bearing functional part |
| Calibration cube, solid | Dimensional accuracy, ±0.02mm tolerance | Print a solid engineering part |
| Test tile for acetone | The smooth-finish baseline | Move to the acetone smoothing guide |
General practice: a flat calibration cube at 245°C, 105°C bed, 50°C chamber, fan off, and a clean adhesion-sprayed plate means the profile is ready for larger ABS parts. The seller has not published an ABS profile, so the settings on your spool label are the working record. The companion troubleshooting guide covers the acetone vapor smoothing workflow, the fumes and ventilation notes, and the stringing and blob fixes.
The temp tower and the enclosure temperature
Before the calibration cube, the nozzle temperature needs a small calibration on a test tile. General studio practice: run a temp tower from 220°C to 260°C in 5°C steps, and read the layers against a window light. A layer that reads glossy and quiet at 245°C is the nozzle band, and the lower layers that pop or bubble tell you the spool still needs drying. The seller has not published a temp tower, so the 5°C steps are general practice.
The enclosure temperature range
The enclosure temperature is the single most important warping control, and the range is 40–60°C in general studio practice. A chamber that holds at 50°C around the part cools the layers evenly, and a chamber that runs too hot softens the part mid-print. A chamber that runs too cold lets the corners lift. The seller has not published an enclosure temperature, so the 40–60°C range is general practice. The companion troubleshooting guide covers the warping diagnosis when the corners still lift after the enclosure is warm.
What the Tronxy black ABS competes with on the bench
The listing describes the Tronxy Black ABS as low-odor, low-warp and zero-bubbles, with a glossy finish and heat resistance above 60°C. General studio practice compares the black ABS part on the temperature, the bed prep and the warping control axes rather than the brand name, because the enclosure profile and the clean bed matter more than the label. The roundup compares the Tronxy spool against the common black ABS competitors on the market, and the color comparison guide covers the ABS versus ASA versus PETG differences.
The working takeaway is that a flat black ABS calibration cube at 245°C, 105°C bed, 50°C chamber, fan off, and a clean adhesion-sprayed plate beats a warped 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. ABS's heat resistance above 100°C and its tensile strength of 32–40 MPa are the reasons it suits enclosures, brackets and automotive interior parts rather than display models.
What to do when the first layer still lifts after the prep
A first layer that still lifts after a clean, adhesion-sprayed bed and a warm chamber usually means the Z-offset is too high or the chamber is too cold. General studio practice: lower the Z-offset so the first layer squashes flat, and raise the chamber to 60°C. A first layer that reads as a thin filament instead of a flat sheet is a Z-offset problem, and a first layer that curls on the corners is a chamber temperature problem. The companion troubleshooting guide covers the warping diagnosis table, and this paragraph sets the expectation that the first-layer lift is a prep or chamber problem, not a temperature problem.
Retraction and travel speed after the temperature lock
Once the temp tower locks the nozzle band and the bed prep holds the first layer, the next tune is the retraction and the travel speed. General studio practice raises the retraction 0.5–1.0mm on a stringing cube, and raises the travel speed to 150mm/s, so the nozzle moves fast between gaps and does not have time to ooze. The listing's 30–60mm/s is the print speed, not the travel speed, so the travel tune is a separate setting. The companion troubleshooting guide covers the full retraction diagnostic table, and this paragraph sets the expectation that the travel tune comes after the temperature and the bed prep.
The Bottom Line
The bench verdict: the Tronxy Black ABS spool, $43.99 under SKU CXY08.01.0028, prints flat when the chamber holds at 50°C, the bed runs at 105°C, the fan is off, the first layer runs 5–10°C hotter, and the bed is clean and lightly adhesion-sprayed. Start by warming the enclosure, set the bed to 105°C, turn the fan off, slice a one-wall calibration cube, then watch the corners. The listing's 220–240°C spec table and the 230–270°C recommendation bracket the 220–260°C general-practice band, and the seller has not published an ABS profile. The companion troubleshooting guide covers the warping diagnosis, the stringing and blob fixes, the fumes and ventilation notes, and the acetone vapor smoothing workflow.
Frequently Asked Questions
How do I print ABS without warping?
General studio practice: warm the enclosure to 40–60°C, run the bed at 100–110°C, turn the part fan off, and run the first layer 5–10°C hotter. A clean adhesion-sprayed bed keeps the first layer bonded, and a slow first layer at 30–40mm/s gives the plastic time to grip. The listing's 80–120°C bed band is the envelope, and the seller has not published an ABS profile.
What temperature does ABS print at?
The spec table lists a printing temperature of 220–240°C, and the features recommendation runs 230–270°C. General studio practice narrows that to a 220–260°C band, with 245°C as the starting point. The seller has not published a specific temperature, so the band is general practice. Start at 245°C, then run a temp tower on a calibration cube.
What bed temperature does ABS need?
The spec table lists a heated bed of 80–120°C. General studio practice runs the bed at 100–110°C to stop the bottom layer contracting and the corners lifting. A bed that runs at 80°C lets the corners curl, and a bed that runs at 110°C holds the first layer flat. The seller has not published a specific bed temperature, so the band is general practice.
Do I need an enclosure for ABS?
General studio practice: yes, an enclosure that holds 40–60°C around the part is the single most important warping control. An open bed lets the outer layer cool faster than the inner layer, and the shrinkage pulls the corners off the bed. The seller has not published an enclosure recommendation, so the 40–60°C band is general practice.
Should I run the part cooling fan for ABS?
No. General studio practice turns the part fan off for ABS, or at most 20–30%. A fan chills the outer layer and pulls the corner off the bed, and a warm chamber replaces the fan's job by cooling the layers evenly. The seller has not published a fan setting, so the off choice is general practice.
How hot should the first layer be for ABS?
General studio practice runs the first-layer nozzle 5–10°C hotter than the rest of the print. A hotter first layer flows flatter and grips the bed, and a slow first layer at 30–40mm/s gives the plastic time to bond. The seller has not published a first-layer profile, so the +5–10°C choice is general practice.
How fast should I print ABS?
General studio practice runs the first layer at 30–40mm/s and the rest of the print at 40–60mm/s. A slow first layer gives the plastic time to grip, and a steady mid-speed print keeps the layers bonding without overheating. The seller has not published a speed profile, so the band is general practice.
How do I keep the ABS first layer from lifting?
General studio practice: clean the glass plate with isopropyl, wipe a light adhesion spray, preheat the bed to 105°C and the chamber to 50°C, level the bed, and run the first layer at 30–40mm/s with the fan off. A clean, sprayed bed holds the first layer while the chamber stays warm. The seller has not published a bed-prep sequence, so the steps are general practice.
What printers can run the Tronxy black ABS?
The listing says the spool is compatible with most 1.75mm printers and 3D pens, and the tips note that ABS needs a heated bed. Confirm your printer reaches 240°C on the nozzle and 110°C on the bed, and that you can hold the chamber at 50°C, before ordering. The seller has not published a model-by-model compatibility list, so the temperature bands are the working requirement.
Is the Tronxy black ABS low-odor?
The listing describes the spool as low-odor, low-warp and zero-bubbles. General studio practice still recommends ventilating the print room or using an enclosure with a filtered exhaust, because ABS fumes are a byproduct of the high-temperature melt. The companion troubleshooting guide covers the fumes and ventilation notes, and the seller has not published an odor specification.
