The new ProJet^® MJP 2500W is an affordable 100% RealWax™ pattern 3D printer that adjusts to your workflow, delivering from several short run batches a day to next day typical larger builds at high productivity. These highly accurate, fine wax patterns are directly printed, without tooling time, costs and geometric limitations, for reliable and repeatable direct metal casting efficiency.

RELIABLE REAL WAX CASTING

Pure wax Visijet M2Cast is 100% wax, which will melt at similar temperatures as hand-carved or injected wax. Virtually zero ash content and silky surfaces mitigate any chances of porosity while the lilac-purple color enhances visualization of details for design evaluation/qualification.

Wax printing in general compared to resin-printing has long been considered the superior option, but why? The answer is quite simple: Castability. Resins don’t cast as waxes do. Period. No matter the amount of “waxy material” present on the resin mix, the end result will always be a plastic. It is called polymerization from photopolymers. The most crucial difference in models from wax printing to resin printing is ash content in castings.

The Projet MJP2500W uses RealWax Visijet materials. It is the perfect fit for standard manufacturing configurations.

Resin printing most common problems are the need to adjust burnout cycles, ash content porosity which leads to extra labor necessary for finishing jewelry products. Investment breakage may also occur from casting photopolymer resins. Thermal expansion may ruin entire casting flasks, which are obviously expensive, especially so in dealing with gold, platinum, and higher temperature metals.

It’s important to print RealWax in order to yield high-quality castings consistently.

SPEED AND OPERATIONAL EFFICIENCY

Like on 3-lane highways, speeds will increase when the projected path is a straight line, and you will definitely avoid jams or delays when there’s extra space to diffuse traffic. The all new MJP2500 print head with 880 individual micro-jets runs along the X-axis once, twice, or three times per layer depending on the magnitude of your print job. The aluminum build platform will then recess per layer thickness so as to allow for the next series of drop-mass depositions.

Sacrificial/Dissolving support material allows for 360 degrees of freedom of design; creative liberty that leads to reduced part-count and efficient repeatability.

The Projet MJP2500W uses state-of-the-art, engineered materials for building and supporting parts. Compared to resin printers, such as SLA or DLP technologies, where 3D printed models are supported with the same material as the part itself, and then must be manually cut away by the user. Instead, the MultiJet platform automatically produces a wax support structure underneath your model, which is then easily washed away in a heated, stirred bath. Dissolving support material technology significantly increases the quality of your printed parts by means of eliminating post-processing time and reducing the amount of labor required to finish the model. Simply clean the support material away from your printed parts and the next step is to sprue them on your casting tree.

HIGH-RESOLUTION PATTERNS

The MJP2500W is ideal for those constantly injecting wax into rubber molds. You can print entire trees of rings at once with the 2500W, so it makes less sense to labor and toil with rubber molding and wax injection. In lieu of hundreds of rubber molded sandwiches taking up space on a shelf, you can now digitize your entire production and save time, space, and money. Take your casting production into the 21st century with a lead forward into the latest and greatest wax 3D printing technology.
