ClassINDUSTRIALRESIN
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)UltiMaker S8 3D Printer[1][2]UniFormation GKtwo 10.3" 8K Resin Printer[3][4]
Release date (announcement and actual shipping)Launched March 2025; the technical-specification and pricing announcement is dated 14 March 2025[2]Not documented
Street price (USD; dated snapshot per entry)Starting at $8,999 at MatterHackers, in stock, checked Aug 2026. The launch announcement quoted approximately $9,000[1][2]$749.99 on uniformation3d.com but marked Sold out, checked Aug 2026 (the page shows a compare-at price of $0.00, i.e. none set)[3]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Sold as printer-only or as a Pro Bundle. The bundle is not a trim level but a different machine footprint and weight: 495 x 500 x 1210.5 mm and 47.7 kg with the 6-spool Material Station, versus 495 x 585 x 800.5 mm and 30 kg for the printer alone. Print cores AA+ 0.40 x2 are included; BB, CC+ and DD 0.40 are separate purchases[1][2]UniFormation lists GKtwo variants by region and bundle (GKtwo ALL, GKtwo ALL UK) rather than by hardware, so the hardware specification is common; what changes is what ships in the box. Not to be confused with the earlier GKone[3]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable330 x 240 x 300 mm[1][2]228 x 128 x 245 mm[3][4]

Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Dual-extrusion print head with auto nozzle-lifting, flood detection and inductive probing. UltiMaker's Cheetah motion planner uses third-order continuous motion with corner blending[1][2]MSLA — photocuring LCD, single Z axis, straight-lift peel[3][4]
Speed & Acceleration
Max print speed (claimed, mm/s)Up to 500 mm/s in XY (manufacturer claim)[1][2]Not documented

Jerk / square-corner-velocity setting (exact value)Jerk up to 100,000,000 mm/s3 (manufacturer claim)[1][2]Not documented
Max volumetric flow claimed (mm³/s)Up to 35 mm3/s extrusion flow (manufacturer claim)[1][2]Not documented
Extruder
Type (direct drive / bowden) & design nameDual gripper feeder with tension adjustment, release function and filament feed-rate control[1][2]Not documented
Filament diameter2.85 mm[1][2]Not documented
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Swappable print cores; AA+ 0.40 x2 included, BB 0.40 / CC+ 0.40 / DD 0.40 sold separately[1][2]Not documented
Max nozzle temp claimed AND firmware max temp limit (both values)Up to 340 °C (manufacturer claim)[1][2]Not documented

Materials Support
Officially supported filament listUltiMaker cites 301+ compatible materials including its own PLA, PETG, ABS, CPE, CPE+, PC, TPU and PET-CF, plus third-party grades[1]402.5-405 nm photopolymer resin. No closed compatibility list published[3][4]
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Under 50 dBA operating sound, manufacturer figure. No independent measurement; distance and method not stated[1][2]Not documented
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)12 months, extendable to 5 years with an UltiMakerCare plan[1][2]Not documented
Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)Dimensional accuracy +/-0.15 mm +/-0.15% of feature nominal length (manufacturer specification, not an independent measurement)[1][2]Printing tolerance +/-0.1 mm for lengths up to 100 mm, +/-0.1% beyond — a manufacturer specification, not an independent measurement[3]

Light sourceNot documentedPhotocuring LCD light engine at 402.5-405 nm. UniFormation does not publish the LED count or optical design on this page[3][4]
Layer exposure timesNot documented2-3 s per layer at 0.05 mm layer height (manufacturer figure — one of the few makers here that states the layer height its exposure figure assumes). Sortable value is the midpoint[3][4]
Layer height rangeNot documented0.03, 0.05 and 0.1 mm (three discrete settings, not a continuous range)[3][4]
Resin vat & feedingNot documentedResin vat capacity 0.7 kg, with built-in resin heating: UniFormation quotes warming to 95 F (35 C) in 8 minutes from 50 F. No auto-refill and no level sensing published[3][4]
Fume extractionNot documentedBuilt-in odour filter[3][4]

Manufacturer claims, independent measurements, packages and test conditions retain their source wording. FDM linear speed and resin vertical speed use different units and are not directly comparable. Unknown values are marked “Not documented”. Prices and source dates remain historical snapshots; check the linked guide for product details. Differences highlight text, not a universal winner.
