Flashforge WJ51C: A Desktop Wax Printer Fills the Gap Solidscape Left
3D PrintingWhen Solidscape — the original wax jetting specialist — was shuttered in 2024, it left a specific gap: desktop wax printing for jewelry studios, dental labs, and small-batch metal casting operations. Flashforge’s WJ51C is the most direct answer to that gap yet.
What Happened
Flashforge released the WJ51C, a desktop MultiJet Printing (MJP) wax 3D printer with a 235×138×100mm build volume, 15-micron minimum layer thickness, and dimensional accuracy of ±0.04mm. The print head runs 2,900 × 2,900 × 1,700 DPI with 2,080 jets — resolution that targets the fine detail requirements of jewelry casting, dental applications, and precision metal parts.
The WJ51C uses proprietary wax blocks and soluble support material. Wax runs approximately $0.46/gram; support runs $0.18/gram. The block-based system enables smaller, more economical print runs compared to tank-based systems that require maintaining large material volumes. The printer weighs 115kg and handles up to 4 kilos of wax monthly.
Pricing hasn’t been formally announced, but U.S. distributor financing at $768/month over 60 months suggests a total cost in the $35,000 range — positioning it as professional, not desktop-hobbyist.
Why It Matters
Solidscape’s exit in 2024 was consequential for anyone relying on wax jetting for jewelry and lost-wax casting. The technology — spraying wax droplets layer by layer to build highly accurate positive patterns — is distinct from resin-based alternatives like Formlabs. Resin castables have improved significantly but still require different burnout protocols and produce different casting results than true wax.
Flashforge entering the wax jetting category signals that the technology isn’t dying with Solidscape — it’s being picked up by higher-volume printer manufacturers who can bring the cost of entry down over successive generations. The WJ51C is a first-generation product at a professional price; the competitive dynamic that drove desktop FDM from $3,000 to $300 in five years is likely to follow in wax jetting over the next decade.
For jewelry studios and casting operations currently using resin alternatives or outsourcing wax patterns, the WJ51C introduces a viable in-house option. The ±0.04mm accuracy and 15-micron layers are within the requirements for fine jewelry casting where fit and finish matter.
The So What
Wax printing’s obituary was premature. Flashforge’s entry — from a company that scaled FDM to mass-market volumes — suggests the economics of wax jetting will follow a similar downward trajectory. At current pricing the WJ51C targets professional studios. For jewelry businesses and dental labs that need true wax output, it’s worth evaluating against resin alternatives now and tracking the second-generation pricing in 12–18 months.
