Brand overview →The P1S has the same build volume as the X1 Carbon and an enclosed chamber, but without lidar calibration and at a much friendlier price. A balance of price and functionality for a shop with a steady order flow.
Key specs
- Build volume: 256 × 256 × 256 mm.
- Chamber: fully enclosed with active cooling (an extra part-cooling fan, chamber temperature control, control-board fan) — prints ABS/ASA more stably than open-frame models.
- Speed: up to 500 mm/s, acceleration up to 20,000 mm/s².
- Power draw: about 100 W average while printing (roughly 0.1 kWh per hour) — noticeably lower than the X1 Carbon due to simpler electronics.
Who it suits
- Shops that need an enclosed chamber for ABS/ASA/PETG but don't need the X1 Carbon's lidar calibration.
- An order flow where the price-to-print-stability ratio for engineering plastics matters.
What to watch for in cost calculation
~100 W is the rated average — accurate for steady-state printing; power draw is briefly higher while heating the bed and nozzle, but for hourly cost calculation the average figure is more accurate.
