ClassCOREXYCOREXY
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Original Prusa XL+, Single-Tool variant ("Prusa XL+ Single-Tool" in the e-shop variant data)[1][2]QIDI Max4, sold as "Max4 High-Temp 3D Printer"[3][4]
Release date (announcement and actual shipping)The XL+ refresh was announced on 13 August 2026, on sale immediately in all toolhead configurations, with assembled printers shipping later in August 2026 and upgrade kits for existing XL owners from around the end of August. The original Original Prusa XL predates it[5]Not published on QIDI's product page; the machine is listed as the current replacement for the discontinued X-Max 3 (checked Aug 2026)[3][6]
Street price (USD; dated snapshot per entry)$2,128.70 on prusa3d.com, Aug 2026 (lowest listed price for the Single-Tool variant; the Enclosure bundle starts at $2,610.19)[1]$1,099.00 standard on us.qidi3d.com against a $1,149.00 compare-at price, checked Aug 2026. Variants: Polar Cooler bundle $1,249.00 (was $1,348.00), Max4 Combo $1,249.00 (was $1,299.00), Combo + Polar Cooler $1,399.00[3]
Variants & sibling models — and how to tell them apart (spec-contamination risk)The XL+ is sold in Single-Tool, Dual-Head and Five-Head variants at $2,128.70, $2,768.52 and $3,610.18 respectively (Aug 2026), plus Enclosure bundles and a Critical Infrastructure edition. The frame is the same in all of them - Prusa states the frame is ready for toolheads to be added at any time - so build volume, bed and electronics figures are shared and only the toolhead count and price differ. The XL+ is itself a revision of the Original Prusa XL: the older XL aligned toolheads with a mechanical pin, the XL+ uses a dedicated electronic sensor, adds a nozzle wiper and is claimed to print 10-15% faster[1][2]Four variants at the US store: Standard, Polar Cooler bundle, Combo (adds QIDI Box), Combo + Polar Cooler. Direct replacement for the X-Max 3, which it differs from on every headline figure: 390x390x340 vs 325x325x315, 800 vs 600 mm/s, 370 vs 350 °C. Do not carry X-Max 3 specs across[3][6]
Market position: superseded? successor announced?Current model; an Original Prusa XL to Prusa XL+ upgrade kit is sold for existing owners[2]Current large-format flagship as of Aug 2026; QIDI's X-Max 3 page directs buyers here[3][6]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable360 x 360 x 360 mm, which Prusa states as 46.7 litres[1]390 x 390 x 340 mm advertised[3][4]
Machine footprint (mm) & clearance needed (cable/spool overhang)About 700 x 900 x 720 mm (Prusa's own figure is approximate)[1]558 x 578 x 612 mm[4]
Net weight (kg)About 30 kg[1]46.5 kg net[4]
Frame construction & materialAluminium extrusions and steel sheets (Prusa's comparison table for the XL)[7]Enclosed CoreXY chassis; QIDI does not publish a frame-material breakdown[3]
Enclosure: open / enclosed; panel material; door/lidOpen frame. The Enclosure for Prusa XL+ is an optional add-on; Prusa says the printer is ready for chamber temperatures up to 60 C, that the new better-sealed enclosure reaches around 50 C on the printer's own waste heat, and that 60 C needs an upcoming chamber heater for which no shipping date has been given[1][5]Fully enclosed with a 3-in-1 air filter (G3 pre-filter + H12 HEPA + coconut-shell activated carbon)[4]
Passive chamber temperature reached (if enclosed; measured values preferred)Not documented65 °C, independent active chamber heating (manufacturer claim), with a 4-pin PWM chamber fan with RPM feedback[4]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY with 1.5 mm GT belts, Input Shaper and Phase Stepping[1]CoreXY[4]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashNot documented2 mm lead Z screw with an anti-backlash nut[3]
Belts (type, width, e.g. Gates?)1.5 mm GT belts[1]Not documented
Stepper motors (frame size, step angle, brand if known)Not documentedFOC closed-loop stepper motors[4]
Speed & Acceleration
Max print speed (claimed, mm/s)Not documented800 mm/s (manufacturer claim, maximum)[4]
Max acceleration (claimed, mm/s²)Not documented30,000 mm/s2 (manufacturer claim, maximum)[4]
Max volumetric flow claimed (mm³/s)Not documented40 mm3/s rated flow (manufacturer claim)[4]
Vibration Compensation / Input Shaping
Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary)Input Shaper and Phase Stepping[1]Input shaper listed as a feature[4]
Extruder
Type (direct drive / bowden) & design nameNextruder direct drive; each toolhead carries its own extruder, hotend, nozzle and filament[1]Direct drive, dual hardened-steel gears, 8.9:1 reduction[4]
Gear ratio & drive gear materialNot documented8.9:1; drive gears hardened steel[4]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Quick-swap nozzles - 0.25 mm for detail, 0.6/0.8 mm for speed, hardened steel for abrasives, high-flow CHT for throughput; toolheads ship with high-flow nozzles[1]Multi-metal hotend with a ceramic heater and a 0.4 mm bimetal nozzle; ceramic throat[4]
Max nozzle temp claimed AND firmware max temp limit (both values)290 C claimed max nozzle temperature[1]<=370 °C claimed[3][4]
Heated Bed & Surface
Max bed temp claimed AND firmware limit120 C max heatbed temperature[1]<=120 °C claimed on a 390 x 390 mm bed QIDI markets as ultra-uniform (no thermal imaging published)[3][4]
Bed surface (material, texture, coating), single/double-sidedSegmented heatbed of 16 individually controlled tiles across the 360 x 360 mm surface, so only the tiles under the part are powered; removable double-sided satin print sheet supplied[1]Aluminium plate with silicone heater; double-sided magnetic PEI build plate[4]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Load-cell sensor - the nozzle is the probe, which Prusa says automatically accounts for nozzle changes, surface textures and thermal expansion and removes manual Z-offsets. Toolhead-to-toolhead alignment on the XL+ uses a separate permanently mounted eddy-current Tool Offset Sensor, replacing the removable mechanical pin used on the original XL[1][5]Automatic levelling; probe technology not named by QIDI[4]
Filament Handling & Detection
Filament runout sensor (type, location)Filament sensors fitted; Prusa's comparison table lists two filament sensors for the XL[7]Filament run-out sensor and filament tangle detection (tangle mechanism not described), plus a filament cutter[4]
Multi-material/multi-color capability or official upgrade pathNot documentedQIDI Box multi-colour unit supported; sold bundled as the Max4 Combo[3][4]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting design360-degree part cooling on each toolhead, new on the XL+ and matching the MK4S and CORE One arrangement; Prusa states it delivers more airflow and distributes it more evenly around the nozzle. Additional fans and heatsinks cool the electronics. Fan sizes are not published[1][5]Toolhead, model and auxiliary fans are all 4-pin PWM with RPM feedback; mainboard and chamber fans are closed-loop, chamber fan high-power turbo[4]
Chamber/exhaust fan & filtration (activated carbon / HEPA)Not documented3-in-1 filtration: G3 pre-filter, H12 HEPA, coconut-shell activated carbon[4]
