QIDI Q1 Pro for TPU: Is It Still a Good Buy?

The QIDI Q1 Pro is good for mainstream TPU, especially for an owner who already has one. QIDI lists TPU as compatible and the machine uses a direct extruder with hardened-steel drive gears, a 0.4 mm bimetal nozzle, and a 245 x 245 x 240 mm build volume. That is a credible foundation for ordinary 95A-class flexible parts when the filament, feed path, profile, surface, and moisture state are controlled.

It is no longer an obvious new purchase. QIDI now says the Q1 Pro is discontinued and identifies the Q2 as its direct replacement. A remaining-stock or used Q1 Pro can still be a sensible value if it is meaningfully cheaper and you also want its broader enclosed-material range. TPU alone rarely justifies paying near-current-machine money for it.

This is an evidence-based buyer guide, not a hands-on test. Used condition, regional stock, replacement parts, firmware, profiles, filament formulations, and support terms can change. Confirm the exact machine and current manufacturer documentation before buying.

QIDI Q1 Pro TPU verdict at a glance

The current buying fact: the Q1 Pro is discontinued

QIDI's current product page says the Q1 Pro is no longer in production and calls the Q2 its direct replacement. It also says spare parts and support for existing Q1 Pro owners remain available. That changes the decision from a simple specification comparison into a condition-and-value decision.

For an existing owner, discontinued does not mean unusable. The hardware does not stop printing TPU because a successor exists. For a shopper, however, price must reflect the older platform, remaining warranty, seller return rights, local parts access, and the risk of inheriting wear or modifications.

Use the QIDI Q2 buyer guide when the price gap is small. Use the broader Q1 Pro review when the discounted machine still appeals for more than flexible filament.

What the Q1 Pro hardware actually gives TPU

QIDI's current specifications list a 245 x 245 x 240 mm print size, direct extruder, hardened-steel extruder gears, a 0.4 mm bimetal nozzle, a dual-sided textured PEI plate, a nozzle limit up to 350 °C, a bed limit up to 120 °C, and independent chamber heating up to 60 °C. The same page lists TPU among compatible filaments.

Only some of those facts are important to flexible printing:

• The direct extruder is the useful part. It keeps the driven path near the hotend, reducing the long unsupported compression problem that can make soft filament buckle.
• Hardened gears are durable, not a TPU guarantee. Too much tension can still deform a flexible strand, while too little can slip.
• The 0.4 mm nozzle is a reasonable starting point. The correct diameter still depends on the exact filament, profile, detail, flow demand, and any additives.
• The chamber is not the main TPU benefit. A maximum capability is not a recommended setting. Use the filament maker's current profile and do not heat the chamber merely because the printer can.
• The build volume is ordinary mid-size room. It is useful for pads, guards, sleeves, gaskets, and small flexible fixtures, but it is not a large-format reason to choose an older machine.

TPU compatibility is not one yes-or-no setting

QIDI's current filament catalog includes a TPU95A-HF product described as flexible, high resilience, and intended to support high-speed printing. That proves why the word TPU needs a formulation boundary: a tuned 95A high-flow product is not the same feed problem as a much softer flexible filament from another maker.

Before buying or tuning, record the exact manufacturer, product name, Shore hardness, diameter, color, lot, recommended nozzle and bed range, drying instruction, and available QIDI Slicer or Orca profile. If the filament maker provides a current machine profile, start there. Do not copy a high-speed 95A result onto an unknown soft formulation.

For part selection, use the functional TPU use-case guide. TPU can be excellent for feet, bumpers, grips, strain relief, dust covers, compliant interfaces, and protective guards. It is not automatically correct for a structural beam, bearing surface, certified seal, high-temperature part, or safety-critical component.

Feed-path control matters more than chamber temperature

A direct extruder helps after filament reaches the toolhead. It does not remove drag before the extruder. A stiff guide-tube bend, crossed spool winding, tight dry-box outlet, heavy spool, poor holder alignment, or excessive idler pressure can still compress and buckle TPU.

1. Make sure the spool rotates freely and cannot rub a wall or lid.
2. Keep bends broad and the path as short as the setup allows.
3. Load slowly and confirm the filament enters the extruder without shaving or folding.
4. Use the current profile's conservative speed and retraction values before changing them.
5. Change one variable at a time, then repeat the same coupon.

If under-extrusion appears only after travel moves or many retractions, investigate path drag, idler deformation, heat, and retraction before raising temperature. If the main symptom is fine hairs, use the TPU stringing guide rather than treating every string as a machine defect.

Chamber, cooling, surface, and removal boundaries

The Q1 Pro's active chamber is valuable for materials such as ABS, ASA, PA, and PC, which is why the machine can make sense as a broader functional platform. TPU alone usually does not need that heated environment. Excess heat can make some flexible feed paths less stable, so follow the exact material profile and keep the chamber decision separate from the printer's maximum specification.

Cooling, speed, wall thickness, overhangs, and support strategy interact. Flexible bridges and overhangs can sag, while dense flexible supports may be miserable to remove. Design chamfers, radii, mechanical locks, and accessible support interfaces before trying to solve poor geometry with more slicer complexity.

QIDI lists a dual-sided textured PEI plate. Flexible materials can bond aggressively to some surfaces. Follow the plate and filament maker's current preparation and release instructions, let the part cool, and use a compatible separation method where required. Do not pry hard enough to turn good adhesion into plate damage.

Moisture can make a good printer look bad

Wet TPU can produce popping, bubbles, rough surfaces, inconsistent flow, excessive stringing, and weaker-looking extrusion. Dry according to the exact filament maker's temperature and time, make sure the dryer and spool can safely tolerate that schedule, and store the spool sealed afterward.

A compact dryer such as the SUNLU S1 Plus can be useful single-spool hardware, but the product name is not proof that it reaches the correct schedule for every TPU. Verify its current operating range against the filament maker's instruction before relying on it. The TPU dryer-versus-storage guide owns that decision.

If a part separates on printed layer boundaries during bending, use the TPU layer-cracking diagnosis. Moisture, weak interlayer bonding, geometry, cooling, feed instability, and overload are different problems and should not be collapsed into one temperature change.

Run a seven-part proof before calling the setup production-ready

1. Freeze the input. Record filament identity, hardness, lot, drying state, spool path, nozzle, plate, firmware, slicer, and profile.
2. Define acceptance. Set size, flexibility, recovery, surface, fit, layer-bond, load direction, and service-life requirements.
3. Check the machine. Inspect the nozzle, gears, PTFE path, fans, plate, belts, and spool movement, especially on a used unit.
4. Print a feed coupon. Use walls, retractions, bridges, and corners representative of the real job.
5. Print representative geometry. Include the real wall thickness, holes, radii, mating features, and orientation.
6. Condition and test it. Flex, compress, recover, fit, and expose the part to its real heat, chemical, wear, or outdoor environment where relevant.
7. Repeat and time it. A second accepted part and full labor time are better evidence than one lucky sample.

Used Q1 Pro checklist for a TPU buyer

• Confirm the machine completes homing, leveling, heating, extrusion, and a representative print without errors.
• Inspect the extruder gears and path for wear, debris, modifications, and damaged connectors.
• Check nozzle identity and condition instead of assuming the installed part is stock.
• Inspect the PEI plate for gouges, bubbles, contamination, and overly aggressive flexible-material damage.
• Verify chamber, bed, hotend, fans, runout sensor, tangle detection, camera, network, and storage behavior.
• Ask what firmware and slicer profile the seller used and whether factory parts are included.
• Price in a nozzle, plate, maintenance items, dryer or sealed storage, and the possibility of downtime.

A discount is real only after those costs. If the Q1 Pro plus catch-up work approaches the price of a current supported printer, compare the Q2 and the Bambu Lab P2S TPU path before buying.

Who should choose the QIDI Q1 Pro for TPU

• existing Q1 Pro owners who want to add documented 95A-class flexible printing;
• used buyers receiving a meaningful discount on a verified healthy machine;
• shops that also need the Q1 Pro ABS and ASA lane or broader engineering-material range;
• buyers willing to control filament identity, moisture, feed path, profiles, inspection, and repeatability.

Skip it when TPU is the only buying reason, the seller prices it close to a current replacement, the machine's history is unclear, or the parts are small enough that a simpler direct-drive printer solves the same job. Use the Q1 Pro materials guide to test whether the rest of the platform earns its place.

Frequently asked questions

Can the QIDI Q1 Pro print TPU?

Yes. QIDI lists TPU as compatible and specifies a direct extruder with hardened-steel gears. Success still depends on the exact TPU formulation, hardness, profile, moisture state, feed path, surface, and geometry.

Is the QIDI Q1 Pro discontinued?

Yes. QIDI's current product page says it is no longer in production and names the Q2 as its direct replacement, while stating that parts and support remain available for existing owners.

Should the Q1 Pro chamber be heated for TPU?

Not automatically. The 60 °C chamber figure is a maximum machine capability, not a universal TPU setting. Follow the exact filament maker and current printer profile.

Is the Q1 Pro's direct extruder enough for very soft TPU?

It helps, but it is not a guarantee. Very soft formulations can still expose spool drag, path bends, idler pressure, speed, retraction, heat, and moisture problems. Prove the exact spool before buying around it.

Should an existing owner upgrade to the Q2 just for TPU?

Usually not. If the Q1 Pro already produces accepted flexible parts reliably, a successor does not create a TPU problem. Upgrade only when a documented capacity, support, workflow, or reliability limit justifies it.

Bottom line

Keep and use a healthy QIDI Q1 Pro for TPU. Its official TPU compatibility, direct extruder, hardened-steel gears, and mid-size build volume make it a credible flexible-material platform when the exact filament and process are controlled.

Buy one now only when discontinued status is reflected in the price and the broader enclosed-material workflow matters. TPU alone is not a strong reason to choose an older heated-chamber machine. Verify condition, parts, support, profile, moisture control, feed path, and two repeatable accepted parts before calling it a bargain.
