What Materials Can the AON3D M2+ Print?

Direct answer: AON3D lists ABS, ASA, nylon PA6/6-66/12, PAEK, PC, PEEK, PEI/ULTEM 9085 and 1010, PEKK, PETG, POM, PP, PPSU, PSU, PVDF, TPE and TPU as compatible with the M2+. Its specification also lists carbon-fiber, glass-fiber, Kevlar and ESD-safe versions of those polymers plus soluble and breakaway supports. That is an unusually broad machine envelope, but it is not a promise that every brand, grade or support pair has an AON3D profile or receives the same support.

The decision hinges on three separate levels. A material family can be manufacturer-listed for the machine; an exact commercial grade can be AON3D-validated with a starting profile; or a third-party grade can require user-owned process development. The M2+ is built for high-temperature filament and abrasive composites, but drying, chamber schedule, nozzle, surface, support pairing, ventilation and finished-part evidence still have veto power. Pellets, vat resin, powder, wire, paste and continuous-fiber placement are poor fits because the official records describe a 1.75 mm fused-filament system.

AON3D M2+ material compatibility at a glance

What AON3D's current M2+ records establish

AON3D documents dual independent extruders, a 135 °C actively heated chamber, 500 °C-plus extruders, a 200 °C-plus bed, stainless composite-ready extrusion hardware, swappable surfaces and 1.75 mm filament. Its 2022 specification sheet lists a standard 0.6 mm nozzle and available sizes from 0.2 through 1.2 mm. Those are meaningful high-temperature and abrasive-material capabilities, not proof that every spool inside those numeric limits will adhere, crystallize, cool, release or meet the intended property.

The official product page and linked specification sheet disagree on the current Z build dimension: the page states 450 × 450 × 640 mm, while the 2022 sheet states 450 × 450 × 565 mm. This material guide does not silently resolve that procurement detail. Confirm the offered machine configuration, build height, installed surfaces, nozzle set, software, service and warranty in the current AON3D quotation.

The M2 documentation adds an important support boundary. AON3D says customers are free to use any brand and type of material, but it provides support only for AON3D-validated materials for which its applications team developed processes. The supplied profiles are starting points and may need adjustment for application and geometry. "Open material" therefore means process freedom, not automatic validation or unlimited manufacturer support.

Manufacturer-listed is not the same as AON3D-validated

The broad compatibility list describes families the machine is intended to process. The M2 material library names exact validated grades, including AON3D Readyprint ABS, ASA, PETG, PC, TPU-92A, carbon-fiber ABS, carbon-fiber PETG, ESD ABS, PEI-9085, PEKK-A and PPSU. It also documents third-party grades such as Jabil nylons, carbon-fiber nylon, Kimya carbon PEKK, Solvay carbon-filled PEEK, Solvay PEEK and PPSU, Victrex AM 200, HIPS, AquaSys 120/180 and high-temperature support materials.

That exact-grade library is the cleanest starting point because it supplies handling guidance and base profiles tied to printer model, material, nozzle and single- or dual-extruder use. Even then, AON3D states that application and geometry can require adjustment. Save a modified process under a new name, record the material lot and do not overwrite the baseline that lets you diagnose a change.

A third-party grade can still be a legitimate M2+ candidate. It simply moves responsibility to the process owner: obtain current technical and safety data, confirm diameter and filler, define drying and storage, choose nozzle and surface, establish chamber and cooling, qualify support and purge, then test the finished requirement. A family name or a hotend maximum is not sufficient approval.

ABS, ASA and PETG: ordinary names still hide grade differences

AON3D lists all three and documents validated Readyprint options. The actively heated chamber can reduce the draft and shrink problems seen on open desktop printers, but maximum chamber heat is not automatically the correct process. Large cross-sections, thin-to-thick transitions, support contact and cooldown can create residual stress even when a part stays attached.

PETG is a lower-temperature path, yet moisture, surface choice and release still matter. ABS and ASA add a stronger emissions and environment decision. Use the grade's safety data and facility controls. An enclosed hot chamber contains the process; it does not by itself prove that ultrafine particles or volatile compounds are captured, filtered or exhausted safely.

Do not move a successful profile between standard, flame-retardant, ESD, recycled, reinforced or high-flow versions without review. Additives can change abrasion, shrink, electrical behavior and property evidence. The material label describes a family, while the technical data sheet describes the purchased formulation.

Nylon, PC and filled composites: conditioning and wear remain gates

The specification lists nylon PA6, PA6/66 and PA12 plus PC. These are not one moisture or chamber problem. Recovery drying can require a different tool and schedule from dry holding during a print. Use the nylon drying-versus-storage guide for that distinction and the engineering-material dryer-versus-oven guide when a calibrated process oven may be necessary.

AON3D calls the extruders carbon/glass-fiber ready and lists carbon, glass, Kevlar and ESD variants without an upgrade. That supports the machine-level capability. It does not eliminate grade-level nozzle-size, filler-loading, erosion, drive wear or surface questions. The nylon-CF drying guide also explains why reinforcement does not remove the base polymer's moisture behavior.

Cutting, drilling or sanding reinforced parts can create fine dust and exposed fibers. Plan local extraction, housekeeping and PPE for the exact material and operation. Mechanical-property claims need the supplier's test method, orientation, conditioning and specimen context; a successful print is not design allowables for every load case.

PEEK, PEKK, PAEK and ULTEM: this is the M2+'s core lane

AON3D positions the M2+ for PEEK, PEKK and ULTEM, and the M2 library includes validated PEEK, carbon-filled PEEK, PEKK, PEI-9085, PPSU and other high-performance grades. The 135 °C chamber, 500 °C-plus extruders and 200 °C-plus bed create real process headroom. They do not make polymer history optional.

PEEK-family crystallinity depends on thermal history. PEKK formulations can be tuned toward different crystallization behavior. PEI grades differ from one another, and a ULTEM trade name does not establish a finished-part certification. Drying, dwell, purge, chamber schedule, build surface, support interface, cooling and annealing can alter dimensions and properties. Qualify representative geometry and measure after the conditioning state that matches service.

For aerospace, medical, rail, electrical, pressure, flame/smoke/toxicity or other regulated work, grade identity, traceability and an approved process become part of the material decision. Machine sensor access may support a quality system, but owning the printer does not supply certification. Use applicable standards, qualified personnel and independent inspection where the consequence of failure requires them.

If large, repeat high-temperature work is the requirement, compare the M2+ with the newer AON3D Hylo material router using current quotations and exact process needs. If the work is mostly lower-temperature nylon or carbon-filled parts, the nylon and carbon-fiber printer guide may expose a simpler ownership path.

PPSU, PSU, PVDF, POM and PP: listed but not interchangeable

These families occupy different process and service regimes. PP can be difficult to hold because of low surface energy and shrink. POM needs careful thermal control and safety review. PVDF grades vary in chemistry and intended exposure. PPSU and PSU bring high-temperature handling and application-specific evidence. AON3D's list makes them valid machine candidates, not shared recipes.

Start with an exact supported or supplier-documented grade. Define the acceptance requirement before printing: dimensions after conditioning, chemical exposure, sterilization cycles, creep, fatigue, dielectric behavior or flame response may matter more than appearance. Match the build sheet, release method, support and cooldown to that job.

Compatibility also does not establish economic fit. The official sources do not provide an independent utilization, labor, scrap, service-response, cost-per-part or payback result for a particular shop. Build any ownership case from qualified geometry, real quotations, facility costs, expected queue, acceptable yield and support terms. A broad material list creates options; unused options do not create ROI.

TPE, TPU and dual-material support: pairing is the decision

TPE and TPU appear on the compatible list, and the material library documents a validated TPU-92A. That does not approve every flexible formulation. Shore hardness, dimensional tolerance, spool drag, moisture and the chosen loading path can change feed behavior. Begin with a documented grade and stop when repeated buckling, grinding or inconsistent flow shows that the assumed process is not stable.

Dual independent extruders are useful for soluble or breakaway support, but the pair needs a shared thermal window, reliable inter-material adhesion during the build and the intended separation afterward. AON3D documents HIPS, AquaSys and high-temperature supports for specific workflows. Use the exact profile naming, nozzle and support pairing rather than assuming that any soluble filament can accompany any model polymer. The multi-toolhead printer guide explains why independent-tool support work is a different decision from color-only changing.

Soluble support adds handling and disposal questions. Keep moisture-sensitive support conditioned, follow the supplier's solution and disposal instructions, and do not pour an unidentified polymer-laden bath into a drain. Local rules and support chemistry determine the correct route.

Surfaces, drying and process qualification

The M2+ specification names CF-PEEK, PEI, PC, PPSU and other print-surface options, with reusable plates or disposable sheets. Surface names are not universal recipes. Match chemistry, preparation, release layer and cooldown to the polymer. Excessive grip can damage a part or sheet, while insufficient grip can warp or detach.

Record the exact material lot, moisture history, nozzle, surface, chamber schedule, tool assignment, support, orientation, purge and post-process. Print geometry that represents the actual walls, overhangs and thermal mass. Measure after the relevant conditioning interval and test the load, heat, chemistry, fatigue or insulation property that matters. A starting profile reduces setup effort; it is not the acceptance result.

For a new part, start with the custom-part material chooser rather than selecting the most exotic polymer the machine can reach. The right process is the least complicated one that meets the real environment and evidence requirement.

Facility, electrical and safety boundaries

The specification lists installed dimensions of 1450 × 955 × 1150 mm and 208-230 VAC, 50/60 Hz, 24.5 A single-phase power. Confirm the current configuration and installation manual with AON3D before planning the site. Qualified personnel should address electrical protection, floor capacity, rigging, access, service clearance, ventilation, heat rejection and emergency procedures.

Follow AON3D's current operating instructions and each material's safety data. Preserve guards, interlocks, sensor paths and cooling. Plan for hot surfaces, moving mechanisms, purge waste and abnormal heating. Do not improvise electrical or exhaust work, and do not treat an enclosure as proof of exposure control.

NIOSH's safer-3D-printing guidance supports source control, ventilation and high-efficiency filtration. The correct control depends on polymer, temperature, duration and occupancy. Filters require selection, monitoring and replacement; odor is not an exposure measurement. GoodPrints is not the final workplace-safety authority.

Unsupported and poor-fit boundaries

The official records used here describe 1.75 mm filament material extrusion. They do not establish pellet extrusion, vat photopolymerization, powder-bed fusion, wire, paste or continuous-fiber placement. Open parameters and third-party filament access are not permission to install undocumented feed systems or defeat machine safeguards.

Custom filament also involves diameter stability, ovality, filler distribution, brittleness, moisture response, thermal decomposition, nozzle erosion and safe purge or disposal. If a formulation lacks current technical and safety data plus a documented process window, treat it as research feedstock. Keep it out of regulated or safety-critical use until the required evidence exists.

A printable part is not automatically approved for food contact, potable water, medical or implant use, pressure containment, mains insulation, fire barriers, aircraft, vehicle controls or lifting. Grade identity, contamination, voids, anisotropy, creep, fasteners and post-processing can dominate service. Define who accepts the process and what evidence triggers rejection before production begins.

Buyer and owner decision

• Shortlist the M2+ when large high-temperature filament parts, dual extrusion, abrasive composites and open process development are recurring requirements and current AON3D support is confirmed.
• Require a grade-level process review before buying around PEEK, PEKK, ULTEM, PVDF, POM, flexible or soluble-support work.
• Compare the current Hylo offer when purchasing new; the official M2+ records remain live, but configuration, lifecycle, service and build height must come from the current quotation.
• Choose a simpler system when nearly all work is routine PETG, ABS or nylon and the industrial chamber, dual tools and facility burden will not be used.
• Use qualified external production when certification, traceability, validated inspection or facility controls matter more than owning the machine.

For a defined part, request a GoodPrints quote; the custom-printing service FAQ explains the information needed. For repeat production and broader equipment access, use the JC Print Farm route.

Bottom line

The AON3D M2+ has a broad manufacturer-listed filament envelope that genuinely includes high-temperature polymers, reinforced variants and dual-material supports. The useful boundary is support level: a listed family establishes machine intent, a validated grade adds an AON3D process starting point, and any other open-market grade needs process-owner qualification. Buy or keep the M2+ for work that uses its chamber, dual composite-ready extruders, surface options and open controls. Treat every material as conditional on the exact formulation, profile, conditioning, facility and finished-part evidence.
