Specifications are manufacturer rated, as published on each listing and collected 3 November 2026.
Print speed and precision
The P1S listing rates speed at 500mm/s with 20000 mm/s² acceleration. The A1 listing states an acceleration of 10,000 mm/s² without a print speed figure, so the two speeds cannot be compared directly from the listings. The A1 listing adds active flow rate compensation, which adjusts flow from readings to extrude with accuracy, plus full-auto calibration covering Z-offset and bed-leveling. The P1S listing adds automatic bed leveling of its own, so both sides automate the setup steps that matter for a first print.
Build and enclosure
The P1S Combo is a fully enclosed CoreXY machine weighing 47.52 Pounds with product dimensions of 15.3149606143 Inches x 18.0314960446 inches x 15.3149606143 Inches. The enclosure is stated to improve print performance for advanced filaments. The A1 Combo weighs 28.5 pounds with product dimensions of 23.01 inches x 21.06 inches x 16.77 Inches, and the A1 listing states no enclosure. The A1 side adds a simplified touchscreen, a 1-Clip quick swap nozzle for maintenance, and active motor noise canceling for a quiet printing environment. For the enclosure question in general, see enclosed vs open 3D printer.
Materials and filaments
The P1S listing gives a full filament picture: ideal filaments are PLA, PETG, TPU, PVA, PET, ABS and ASA; PA and PC are capable; carbon and glass fiber reinforced polymer is not recommended. The A1 listing states no filament list, but its multi-color story runs through AMS lite, with a note that AMS lite is required and to get the A1 Combo or buy AMS lite separately. The A1 Combo also includes an LED Lamp Kit: print compatible lamp designs, install the included LED Kit, and turn prints into functional decorative lights for DIY lighting projects, custom décor and creative gifts.
Software and ecosystem
Both listings name the MakerWorld model library, and both describe a beginner-friendly setup: the P1S listing gives setup in 15 minutes, while the A1 listing describes full-auto calibration and a simplified touchscreen interface. The P1S title says ready-to-use while its bullets describe setup in 15 minutes, so treat the first print as quick rather than instant. The A1 title reads “Read to Use” while its bullets describe full-auto calibration, a wording quirk rather than a separate claim.
Support and warranty
Both listings state a 1 year term, worded as “1 Year” for the A1 Combo and “1 Year Manufacturer” for the P1S Combo. No other support terms are stated, and neither listing states a laser class, interlock, e-stop or safety certification, so both safety scores are zero.
