ClassINDUSTRIALINDUSTRIAL
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Flashforge Guider 3 Ultra; the FlashForge spec table gives the machine name as "Guider 3 Ultra"[1]UltiMaker Factor 4[2]
Release date (announcement and actual shipping)Not documentedAnnounced 22 April 2024, shown at HANNOVER MESSE 2024 (22-26 April) and TCT Asia (7-9 May 2024)[2]
Launch MSRP (USD)Not documentedStarting at approximately $20,000[2]
Street price (USD; dated snapshot per entry)$2,399.00 against a $3,499.00 regular price on flashforge.com, but the listing checked is the refurbished SKU and is marked Sold out (Aug 2026)[1]Not documented
Variants & sibling models — and how to tell them apart (spec-contamination risk)Top of the Guider 3 series. Build size depends on which head is used: 330 x 330 x 600 mm with one extruder, 300 x 330 x 600 mm with both. Siblings Guider 3 (300x250x340) and Guider 3 Plus (350x350x600) are both single-extruder. A refurbished SKU exists alongside the new machine, so check which one a price refers to[1][3][4]Shares the 330 x 240 x 300 mm envelope with the UltiMaker S5, S7 and S8, which is the single most contaminated figure in UltiMaker's range. What separates the Factor 4 is the actively controlled 70 °C build volume, the climate-controlled 6-spool material station holding humidity below 15%, and HEPA filtration. UltiMaker also sells a Factor 4 Plus[2]

Safety
Certifications (UL/ETL/CE/FCC — verify, don't assume)CE, FCC, RoHS (as printed in FlashForge's own spec table)[1]Not documented
Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)Not documentedDimensional accuracy within +/-0.2 mm or +/-0.2% of feature nominal length; UltiMaker states it tested over 95% print-completion success. Manufacturer figures, not independent measurements[2]

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.
