Direct answer: INTAMSYS currently lists 14 materials for the FUNMAT HT: PEEK, PEEK-CF, PEEK-GF, PEKK, ABS, PC, PPA-CF, PPA-GF, PPS, PA12-CF, PA6/66, PA6-CF, ASA and PLA. The machine is explicitly designed for high-temperature filament work, with a 450 °C all-metal hot end, 160 °C build plate and 90 °C constant-temperature chamber. That is a credible manufacturer capability envelope, not permission to treat every brand, grade, filler or part as interchangeable.
The practical split is narrower than the headline. ABS, ASA, PC and PLA are manufacturer-listed baseline families, though enclosure, surface and ventilation choices still matter. PEEK, PEKK and PPS are core high-temperature candidates but need exact-grade conditioning and process qualification. Carbon- and glass-filled PEEK, PPA and nylon grades are explicitly listed yet add abrasive wear and nozzle-guidance gates. PETG, TPU, PP, POM, PEI/ULTEM, support filaments and other families do not appear in the current FUNMAT HT row used here, so confirm them in writing rather than inferring support from temperatures. Pellets, resin, powder and continuous-fiber feedstocks are different processes and are poor fits by default.
FUNMAT HT material compatibility at a glance
| Material group | Verdict | Decision that matters |
|---|---|---|
| ABS, ASA, PC and PLA | Manufacturer-listed baseline families | Use the exact grade's chamber, surface, cooling and exposure guidance; do not run every material at the machine maximum. |
| PEEK, PEKK and PPS | Explicitly listed; strongly process-conditional | Drying history, thermal profile, crystallinity, build surface, cooldown and acceptance testing decide whether the part is useful. |
| PEEK-CF, PEEK-GF, PPA-CF and PPA-GF | Explicitly listed abrasive composites | Confirm current nozzle material and diameter, wear parts, surface, conditioning and the exact formulation's process data with INTAMSYS. |
| PA12-CF, PA6/66 and PA6-CF | Explicitly listed nylon lane | Moisture control is a gate; filled grades also need wear and finishing controls. |
| PETG, TPU, PP, POM, HIPS, PVA, PEI/ULTEM and other unlisted families | Not established by the current FUNMAT HT list | Ask INTAMSYS for current model-specific written guidance before buying or scheduling production around them. |
| Pellets, resin, powder, paste, wire and continuous fiber | Unsupported or poor fit by default | The official FUNMAT HT record describes filament material extrusion, not these feed technologies. |
What the current INTAMSYS record actually establishes
INTAMSYS presents FUNMAT HT as an affordable desktop-class PEEK printer with a 260 × 260 × 260 mm build volume. The current product page states a 90 °C constant-temperature chamber, 160 °C heated build plate and 450 °C high-temperature extruder with an all-metal hot end. It also identifies automatic leveling, a reusable ceramic-glass plate, filament-runout warning and a 3.2-inch touch screen.
The same page says the machine can print PEEK, PEEK-CF, PEEK-GF, PEKK, PA-CF, PA, PC and ABS without warping or cracking, then supplies the exact 14-item FUNMAT HT row in its current printer comparison. Those are manufacturer claims with scope. They establish legitimate candidacy, not an independent yield, dimensional-accuracy, material-property or production-readiness result for your geometry.
Temperature ceilings are necessary evidence for some polymers, but they do not prove support by themselves. Nozzle construction and wear, chamber uniformity, surface chemistry, drying, residence time, purge behavior, cooling, emissions and material-specific profiles can all decide the outcome. This guide therefore follows the exact current list and treats everything else as unverified until INTAMSYS provides model-specific guidance.
ABS, ASA, PC and PLA: listed, with different chamber decisions
ABS and ASA benefit from a controlled environment on larger or stress-sensitive parts. FUNMAT HT's heated chamber can reduce the temperature gradient that drives curl and layer splitting, but maximum chamber temperature is not the default profile. Use the grade supplier's window and current INTAMSYS procedure. Part mass, wall transitions, support contact, plate preparation and cooldown can still create distortion.
PC is a family, not one recipe. Transparent, impact-modified, flame-retardant, PC/ABS and filled grades can require different conditioning and process settings. Only PC is named in the current FUNMAT HT row; do not silently extend that entry to every blend. For lower-temperature machine selection, the ABS and ASA printer guide helps determine whether the FUNMAT HT's high-temperature envelope would be unused overhead.
PLA is also explicitly listed, but a high-temperature chamber is not automatically helpful. Excess ambient heat can work against cooling and dimensional control on some PLA parts. Follow the material and printer profile instead of leaving the chamber at a high engineering-polymer setting. If most work is PLA, the buyer decision should turn on the real need for the high-temperature lane, not on whether FUNMAT HT can process a basic material.
PEEK, PEKK and PPS: the machine fits the class, not every outcome
PEEK and PEKK are the clearest reasons to shortlist FUNMAT HT. INTAMSYS explicitly positions the printer around PEEK and lists both families. Its thermal architecture provides the relevant process headroom, but high-temperature polymer success depends on the whole thermal history. Drying, nozzle residence time, chamber setpoint, plate interface, support, orientation and controlled cooling can change crystallinity, residual stress, bonding and dimensions.
PPS is also in the exact current list. That does not make every PPS or PPS composite equivalent. Confirm whether the target grade is unfilled or reinforced, its drying and decomposition limits, the approved nozzle and surface, and whether the intended part needs chemical, electrical, flame, thermal or creep evidence. The Plus5 PPS-CF boundary guide illustrates why a family name cannot replace hardware and grade-level qualification, even though FUNMAT HT is a different machine.
For PEEK, PEKK or PPS production, define acceptance before printing. Measure the relevant geometry after the required conditioning interval, and test the property that matters. A successful coupon does not establish fatigue life, pressure capability, dielectric performance, flame response or long-term chemical compatibility for a finished assembly. Compare the AON3D Hylo material-capability router when a larger, hotter industrial platform, documentation or facility workflow may fit better.
Reinforced PEEK and PPA: listed but abrasive
PEEK-CF, PEEK-GF, PPA-CF and PPA-GF appear in the current FUNMAT HT row. That is stronger evidence than inferring composite capability from a 450 °C hot end. It still does not disclose every compatible filler loading, minimum nozzle diameter, nozzle material or replacement interval. Obtain the current INTAMSYS process record for the exact filament and confirm the installed wear path before committing a long job.
Fiber reinforcement can improve selected properties while changing flow, surface finish, anisotropy, notch behavior and failure mode. Published filament data may use controlled specimens and orientations that do not match the part. Treat the supplier's values as scoped evidence, not universal design allowables. Qualify representative walls, holes, inserts and load directions, and document nozzle condition because wear can change extrusion over time.
Post-processing adds another boundary. Cutting, drilling or sanding filled parts can release fine polymer dust and exposed fibers. Use local extraction, housekeeping and PPE selected for the exact material and operation. Do not use compressed air to spread dust around the workspace.
Nylon and nylon composites: moisture stays in charge
INTAMSYS lists PA6/66, PA12-CF and PA6-CF. These are legitimate FUNMAT HT candidates, but nylon can absorb enough moisture to change extrusion, surface, void content and mechanical behavior. A sealed bag or dry cabinet maintains a conditioned spool; it does not necessarily recover material that is already wet. The nylon drying-versus-storage guide separates those jobs, while the nylon-CF drying guide covers the reinforced case.
Follow the exact filament maker's temperature, time and equipment guidance. Do not place a spool in an oven that the spool or appliance cannot safely tolerate, and do not assume a warm spool holder is a calibrated recovery process. The engineering-material dryer-versus-oven comparison explains why active holding, recovery drying and process ovens are different tools.
Filled nylon also returns the abrasive-feedstock question: nozzle material, diameter, drive wear and replacement plan need written confirmation. If the shop mainly prints nylon or carbon-filled nylon rather than high-temperature PAEK polymers, the nylon and carbon-fiber printer guide can reveal a simpler ownership path.
The ceramic-glass plate is not a universal surface answer
INTAMSYS identifies a reusable ceramic-glass plate, but the current marketing page does not establish one surface preparation for all 14 entries. Match any sheet, adhesive or release layer to the exact material and current manufacturer instructions. Maximum grip is not always desirable: a part can damage a coating or glass surface if release is uncontrolled, while insufficient adhesion can allow warping or detachment.
Record plate condition, cleaning method, interface material, first-layer procedure and cooldown as part of the process. Do not transfer a PEEK surface routine to PLA, or an ABS release method to a reinforced nylon, without checking compatibility. If a proposed grade requires another surface, confirm that modification with INTAMSYS before treating it as a supported configuration.
Unlisted materials and wrong-feedstock poor fits
PETG, TPU, PP, POM, HIPS, PVA, PEI/ULTEM and many specialty families may appear on other INTAMSYS printer or material pages, but they are not in the current 14-item FUNMAT HT row used for this decision. That is not proof the machine can never extrude them. It is a boundary on what this source establishes. Ask INTAMSYS to confirm the exact model, grade, nozzle, plate, chamber and software path in writing before buying material or promising delivery.
Soluble support needs a compatible thermal window, in-process adhesion and a safe removal and disposal plan. Flexible filament needs a verified feed path and hardness range. Low-surface-energy materials such as PP can demand a specialized build interface. PEI/ULTEM requires more than enough nozzle temperature. None should be promoted from "possible" to "supported" without current model-specific evidence.
Pellet extrusion, vat resin, powder-bed fusion, paste, wire and continuous-fiber placement are different feed technologies. The FUNMAT HT page describes filament material extrusion. An open or adjustable process is not approval for a different feed system, and a temperature ceiling is not evidence that a custom compound is safe or reliable.
Ventilation, fire, electrical and operating boundaries
High-temperature extrusion can release particles and volatile compounds, and the mix depends on polymer, additives, temperature and duration. A closed heated chamber is useful process hardware but is not proof of exposure control. NIOSH's safer-3D-printing guidance supports source capture, ventilation and high-efficiency filtration as engineering-control options. Select controls for the actual material and occupancy, maintain them, and do not use odor as a measurement.
Follow the current INTAMSYS installation, operating and maintenance instructions and every filament safety data sheet. A qualified person should confirm electrical service, circuit protection, placement, clearances and ventilation for the installed machine. Keep combustibles controlled, preserve guards and interlocks, and train operators for jams, abnormal heating, power loss and safe removal of hot material. GoodPrints is not the final workplace-safety, electrical, fire-code or industrial-hygiene authority.
Finished-part safety remains separate from printability. A listed material does not automatically make a part suitable for food contact, potable water, medical use, pressure containment, mains insulation, fire barriers, aircraft, vehicle controls or lifting. Grade identity, contamination, voids, anisotropy, fasteners, sterilization, creep and post-processing can dominate service behavior.
A practical qualification checklist
Start with one exact manufacturer, grade and lot rather than a family label. Collect the current technical data sheet, safety data sheet, drying instructions and INTAMSYS model-specific process guidance. Record the installed nozzle, its condition, plate or interface, material conditioning history, chamber and bed settings, toolpath version, orientation, support, cooldown and any post-process. If one of those variables changes, decide whether the change requires partial or full requalification.
Use representative geometry, not only a small calibration shape. Include the wall thicknesses, holes, inserts, overhangs, thermal mass and support interfaces that create risk in the real part. Inspect for warping, delamination, voids, surface damage and dimensional drift after the relevant conditioning period. When the application depends on heat, chemicals, fatigue, electrical behavior or sustained load, test that requirement with a method appropriate to the intended use.
Set stop rules before the job begins. Unexpected odor or smoke, repeated feed resistance, visible nozzle wear, unstable extrusion, plate damage, chamber alarms or a departure from the approved process should trigger a safe pause and review. Do not rescue an expensive spool or deadline by disabling safeguards or improvising a higher-temperature profile. A documented failed trial is more useful than an undocumented part that merely looks complete.
Buyer and owner decision
- Shortlist FUNMAT HT when repeated PEEK, PEKK, PPS or explicitly listed reinforced-filament work fits its 260 mm cube and a 90 °C chamber is appropriate.
- Choose a simpler printer when nearly all work is PLA, ABS, ASA, routine PC or nylon and the high-temperature polymers will not be qualified or used.
- Pause for written confirmation when the business case depends on PETG, TPU, PP, POM, PEI/ULTEM, soluble support, a specialty blend or an exact composite not named in the current FUNMAT HT record.
- Use qualified external production when certified material, validated properties, traceability, inspection or low-volume high-temperature work matters more than owning the process.
Start with the part material decision and the custom-printing service FAQ. For a defined part, request a GoodPrints quote; for repeat production and broader equipment access, use the JC Print Farm route.
Bottom line
FUNMAT HT has a clear, current manufacturer-listed lane: 14 materials spanning PLA and ABS through PEEK, PEKK, PPS and several abrasive composites. Use that list as the starting boundary. The machine's thermal specifications make those materials credible candidates, but exact-grade drying, nozzle and wear guidance, chamber strategy, surface, ventilation and finished-part evidence still decide whether the result is acceptable. Treat every unlisted family as unverified until INTAMSYS supplies current model-specific guidance.
