PEEK-250

The PEEK-250's 200°C active heated chamber is the key differentiator. Most desktop high-temperature printers max out at 90–120°C chamber temperature — enough for ABS and basic nylon, but insufficient for PEEK, PEI ULTEM, or PEKK. These ultra-performance polymers require a 160–200°C ambient environment during printing to crystallize properly and achieve full mechanical properties. Below this temperature, the same materials print but exhibit internal stress, micro-cracking, and significantly reduced strength, chemical resistance, and heat deflection. The PEEK-250's 200°C chamber, combined with a 480°C water-cooled extruder and Direct Annealing System, enables production-quality PEEK, PEI 1010, PEI 9085, PEKK, PEEK-CF, and PEEK-GF that no other desktop platform can achieve.

DAS is CreatBot's patented system for annealing printed parts directly inside the printer immediately after the final layer, without removing the part from the platform. Traditional PEEK post-processing requires cooling the part, removing it from the platform, and placing it in a separate furnace — each step introducing thermal shock and handling stress that can deform the part or lock internal stress into the crystalline structure. DAS eliminates all three failure modes: the part remains on the platform, in the controlled chamber environment, while a programmable anneal schedule executes automatically. You set the anneal temperature and duration on the 7-inch touchscreen before starting the print — the printer handles everything from first layer to fully annealed part with no intervention. For PEEK, a typical DAS schedule is 180°C for 5 hours, then 120°C for 5 hours before cooling.

The PEEK-250 requires a dedicated 240V / 20A electrical circuit at 2500W rated capacity. The machine weighs 120kg and measures 630×555×815mm — a standard concrete floor is sufficient, no special reinforcement needed. The three-layer aviation-grade thermal insulation keeps the exterior below 40°C even at maximum chamber temperature, so a standard lab or production environment does not require additional ventilation or a heat-isolated room. WiFi connectivity requires standard 2.4GHz access. Rev1 conducts a facility assessment before shipment to confirm all requirements are met and to identify any site preparation needed before the machine arrives.

The PEEK-250 and PEEK-300 share the same 480°C nozzle and 200°C platform rating but differ in two critical areas: build volume and chamber temperature. The PEEK-250 has a 250×250×300mm build volume and a 200°C maximum chamber — the highest in any desktop PEEK printer. The PEEK-300 offers a larger 300×300×400mm build volume (60% more build space) but runs a 120°C maximum chamber temperature. For parts requiring the hottest possible chamber — specifically complex PEEK crystallization and PEI ULTEM at full mechanical performance — the PEEK-250 is the correct choice. For larger parts where the 120°C chamber is sufficient for the material, the PEEK-300 provides more build volume. Rev1 can advise on the right platform for your specific application and material requirements.

Yes — the PEEK-250 supports the full range of engineering polymers including PLA, ABS, ASA, PC, PETG, nylon, PVDF, UltraPA, UltraPA-CF, and PET-CF. For these materials, the chamber temperature is simply set lower (40–80°C range), and the machine operates as a standard high-performance FDM printer. The benefit of running engineering materials in the PEEK-250 is that the chamber temperature control is far more precise than in a passively heated or unheated enclosure — parts in ABS and nylon print with better interlayer bonding and less warping than in a standard printer. Most PEEK-250 customers use the machine for both their ultra-performance polymer work and their routine engineering polymer production, maximizing utilization of the machine throughout the week.

The Intamsys Funmat HT is priced lower at approximately $7,000 and is a legitimate entry point for PEEK printing, but it maxes out at 90°C chamber temperature — less than half the PEEK-250's 200°C. At 90°C, PEEK parts print but do not achieve full crystallinity, resulting in reduced tensile strength, lower heat deflection temperature, and higher susceptibility to chemical attack vs properly crystallized PEEK. The Funmat HT also lacks water cooling on the extruder and has no direct annealing system, meaning post-processing requires a separate furnace. For customers who need production-quality fully crystallized PEEK and PEI ULTEM parts with the highest mechanical properties, the PEEK-250's 200°C chamber, water-cooled extruder, and DAS justify the additional cost. For lower-priority PEEK work or research applications where full crystallinity is not required, the Funmat HT is a cost-effective option — Rev1 can help determine which platform fits your application.
