What your bench jeweler actually checks

Detail you can cast

At 2900 DPI and 15 µm layers, the WJ51C resolves prongs, pavé seats, filigree, and engraving — then burns out clean at under 0.01% ash. Pattern accuracy is ±0.04 mm / 20 mm, so what you model is what you cast, piece after piece.

About this product

The Flashforge WJ51C is the world’s first desktop wax jetting (MultiJet / MJP) 3D printer — it prints 100% castable wax patterns for lost-wax investment casting on a benchtop machine sized for a jewelry studio. A precision piezoelectric printhead lays down 15 µm layers at 2900 × 2900 × 1700 DPI across a 9.25 × 5.43 × 3.94 in / 235 × 138 × 100 mm plate, and a sealed wax-block supply keeps material fresh so a single unit turns out up to 3 kg of ready-to-cast patterns a month.

What Is the WJ51C: Desktop Wax Jetting for Jewelry Casting

The WJ51C brings industrial wax jetting to a desktop footprint. Instead of curing resin, it jets molten casting wax layer by layer alongside a separate dissolvable support wax, so finished patterns are true wax — they burn out clean in a standard investment flask with no ash-forming residue. It is built for jewelry studios, bench jewelers, and small casting workshops that want in-house pattern production without the space, cost, or throughput of a full production wax printer. See full specifications below.

Why jewelers choose the WJ51C

Detail, footprint, and burnout behavior — the things a bench jeweler actually measures.

2900 DPI, 15 µm layers

Resolves prongs, filigree, pavé seats, bezels, and engraving that FDM and lower-resolution wax printers blur.

World’s first desktop wax printer

Industrial MJP wax jetting in an 865 × 510 × 654 mm cabinet that sits on a studio bench — no dedicated casting room required.

±0.04 mm / 20 mm accuracy

Repeatable patterns with 0.7% linear shrinkage — sprue, invest, and cast without chasing dimensional drift piece to piece.

Wax-block supply + dissolvable support

A sealed wax-block feed limits thermal degradation and waste (≥57% material utilization); white support wax rinses away hands-free.

Print Resolution & Pattern Quality

At 2900 × 2900 × 1700 DPI with a 15 µm layer height, the WJ51C holds the surface detail investment casting depends on: sharp stone seats, thin walls, crisp bezel edges, and readable engraving. Dimensional accuracy is stated at ±0.04 mm per 20 mm, with 0.7% linear shrinkage on the red casting wax — predictable enough to build compensation into your CAD library once and reuse it. Two print modes trade speed for build style: a single-channel mode at 7 mm/h and a dual-channel mode at 3.2 mm/h. See full specifications below.

Casting Wax Materials & Burnout Workflow

The WJ51C runs a two-wax system: a red model wax and a white, fully dissolvable support wax, both fed from the sealed block supply.

Material	Role	Key properties
Red casting wax (FFWJ1200)	Model / pattern	Melting point 68 °C · 0.7% linear shrinkage · ash content < 0.01% · 72 g wax block
White support wax (FFMS3200)	Dissolvable support	Melting point 55 °C · hands-free removal in a warm solvent bath · 180 g wax block

Because both are true waxes with very low ash, patterns go straight into a standard gypsum investment flask and burn out cleanly for lost-wax casting — no resin-style residue or expansion surprises. Additive Plus supplies both waxes and can advise on flask, burnout, and casting parameters.

How we deliver it

Configured, installed, and dialed in for your casting workflow — not drop-shipped in a box.

Step 01

Configure

We spec the WJ51C with red casting wax and dissolvable support, sized to your bench space, power, and monthly pattern volume.

Step 02

Install & train

Install, calibrate the printhead, and train your team on WaxJetPrint plus the dissolve-and-invest workflow.

Step 03

Validated patterns

Dialed-in profiles for jewelry casting so patterns leave the plate ready to sprue, invest, and cast.

Software, Connectivity & Setup

Jobs are prepared in WaxJetPrint (STL and SLC input, Windows 10/11 64-bit) and sent over Gigabit Ethernet or USB, with Wi-Fi available as an option. The printer runs on standard single-phase power (AC 100–250 V, 2.2 kW) and asks only for a stable 18–26 °C bench environment — no compressed air or special facilities — which is what makes in-house wax printing realistic for a small studio.

Common questions

Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.

What technology does the Flashforge WJ51C use, and what does it print?

The WJ51C uses MultiJet Printing (MJP) wax jetting — it jets molten casting wax through a precision piezoelectric printhead in 15 µm layers, alongside a separate dissolvable support wax. It prints 100% castable red model wax, so patterns are true wax rather than cured resin and burn out cleanly in a standard investment flask at under 0.01% ash. It is the world's first desktop wax printer, built for lost-wax investment casting of jewelry and other precision small parts.

What is the build volume and resolution of the WJ51C?

The WJ51C has a build volume of 9.25 × 5.43 × 3.94 in / 235 × 138 × 100 mm and prints at 2900 × 2900 × 1700 DPI with a 15 µm layer thickness. Dimensional accuracy is rated at ±0.04 mm per 20 mm. That resolution resolves fine jewelry detail — prongs, filigree, pavé seats, and crisp engraving — while the desktop plate is sized for studio batches of rings and small pieces rather than full production trays.

How is the WJ51C different from the larger WaxJet 530?

Both are Flashforge MJP wax printers with the same 2900 DPI resolution, 15 µm layers, and ±0.04 mm / 20 mm accuracy. The WJ51C is the desktop entry model: a single-printhead machine with a 235 × 138 × 100 mm plate that prints up to about 3 kg of wax patterns a month — right for a jewelry studio or bench. The WaxJet 530 is a triple-printhead production machine with a larger 289 × 208 × 150 mm plate and up to 12 kg/month for high-volume casting bureaus.

What wax materials does the WJ51C use?

The WJ51C runs a two-wax system fed from sealed blocks: FFWJ1200 red model wax (melting point 68 °C, 0.7% linear shrinkage, under 0.01% ash, 72 g blocks) and FFMS3200 white support wax (melting point 55 °C, 180 g blocks) that dissolves away hands-free in a warm solvent bath. The sealed block supply keeps wax fresh and limits thermal degradation, giving ≥57% material utilization. Additive Plus stocks both waxes.

Do WJ51C patterns burn out cleanly for investment casting?

Yes. Because WJ51C patterns are 100% real casting wax — not resin — they go straight into a standard gypsum investment flask and burn out with under 0.01% ash, leaving no resin-style residue or expansion surprises. The red model wax is engineered for lost-wax casting with 0.7% linear shrinkage you can compensate for in CAD. Additive Plus can advise on flask selection, burnout schedule, and casting parameters for your alloys.

What software and connections does the WJ51C need?

Jobs are prepared in Flashforge WaxJetPrint, which accepts STL and SLC files and runs on Windows 10/11 (64-bit). The printer connects over Gigabit Ethernet or USB, with Wi-Fi available as an option. It runs on standard single-phase power (AC 100–250 V, 2.2 kW) in an 18–26 °C room and needs no compressed air or special facilities — part of what makes the WJ51C practical as a desktop machine in a small studio.

How much can the WJ51C produce per month?

A single WJ51C prints up to about 3 kg of red casting wax patterns per month. Actual output depends on part size, nesting, and how many hours the machine runs, but that capacity comfortably covers a jewelry studio's ring, pendant, and small-piece casting. Studios needing higher throughput can step up to the triple-printhead WaxJet 530 (up to 12 kg/month) while keeping the same wax chemistry and dissolve-and-invest workflow.

What is included, and how is the WJ51C delivered?

Additive Plus configures each WJ51C with red casting wax and dissolvable support wax, then installs the machine, calibrates the printhead, and trains your team on WaxJetPrint and the dissolve-and-invest workflow — it is not simply drop-shipped in a box. Lead time is 4–6 weeks, configured to order. A tailored service plan and both consumable waxes are available and kept in stock. Contact us for current WJ51C pricing and a demo.
