Castable Wax

3D Systems Visijet M2 CAST

Castable Wax has a rich blue color, and a weight and surface feel similar to traditional candle wax. Wax products sometimes have white patches caused by slight remnants of the support material, but these should not affect the wax' castability or the final cast product.

Rules and Recommendations

Because Wax products are intended for casting, we have included two values for each design guideline: a rule and a recommendation. The rules are based on what think we can successfully produce in Wax, and we will try to create all products that meet them. The recommendations are based on what we have seen that can be successfully cast into metal. If you do not have extensive casting experience, we strongly suggest that you design based on the recommendations.

Design for Shippability

Wax is incredibly fragile, and can break during shipping despite our best packaging efforts. Keep this in mind when designing your Wax product. Large models with thin wires are particularly susceptible to breakage in shipping.

Min Supported Wall Thickness
A supported wall is one connected to other walls on two or more sides.
0.8 mm
Min Unsupported Wall Thickness
An unsupported wall is one connected to other walls on less than two sides.
1 mm
Min Supported Wires
A wire is a feature whose length is greater than five times its width. A supported wire is connected to walls on both sides.
0.8 mm
Min Unsupported Wires
A wire is a feature whose length is greater than five times its width. An unsupported wire is connected to walls on less than two sides.
1 mm
Min Hole Diameter
The accuracy of a hole not only depends on the diameter of the hole, but also on the thickness of the wall through which the hole is printed. The thicker the wall section, the less accurate the hole becomes. Through holes must also allow for line-of-sight clearance to ensure all material is cleared during post-processing.
1 mm
Min Embossed Detail
A detail is a feature whose length is less than twice its width.
The minimum detail is determined by the printer’s resolution.When detail dimensions are below the minimum, the printer may not be able to accurately replicate them. Details that are too small can also be smoothed over in the polishing process.
To ensure details come out clearly, make them larger than the indicated minimum. We may refrain from printing products with details smaller than the minimum, since the final product will not be true to your design. If your product has details smaller than the minimum, try making them larger, removing them, or considering a material with finer detail.
0.4 mm
Min Engraved Detail
A detail is a feature whose length is less than twice its width. Engraved or debossed details go into a surface.
0.4 mm
Min Clearance
Clearance is the space between any two parts, walls or wires.
To ensure a successful product, make the clearance between parts, walls, and wires greater than the indicated minimum. If your clearance is too small, try making the gap bigger, or consider fusing the parts or features if their independence is unnecessary. You can also try a material with a smaller minimum clearance.
0.3 mm
Min Escape Holes
Escape holes allow unbuilt material inside hollow products to be removed.
Normally you don’t need to consider this, our technician will add escape holes before printing.
When products contain hollow cavities, they are often filled with powder/liquid even after they are removed from the build tray. If escape holes are not large enough, or the geometry of the product makes it difficult to shake or blast the powder out, we cannot successfully clean it.
0 mm
Interlocking/moving or enclosed parts?
Sometimes the interlocking/moving parts can’t be printed, since the supports inside the cross section can’t be removed.
Require Support Material?
Because each layer needs to build off the last, for some material, angles of more than 45 degrees generally require supports to be printed along with the design. Supports are not inherently detrimental for your design, but they do add complexity to the printing process and lead to less smooth finish on overhanging parts.

Material Spec Sheet

Castable Wax is 3D printed using Wax Jetting (Wax 3D printing) technology.

Wax Jetting Process

Wax 3D printing and lost-wax casting are used to build your design when using this material. The wax printing process is a type of Stereolithography/Multi material jetting that uses a wax-like resin. Support structures are printed along with the model to make sure your model doesn’t fall apart. These support structures are automatically generated and manually removed after the printing process. After support structures are removed and your model is cleaned, the model can be prepared for casting.

First, one or more wax sprues will be attached to your model. Next, the sprue and model will be attached to a wax ‘tree’, together with a bunch of other models. The tree is then placed in a flask and covered in fine plaster. When the plaster solidifies, it forms a mold for copper casting. The plaster mold is then put in an oven and heated for several hours to a point where the wax is completely burned out.

Then, molten copper is poured in to fill the cavities left by the wax. Once the copper has cooled and solidified, the plaster mold is broken and the copper models are removed by hand. Then, your model is filed and sanded to get rid of the sprues, and finally polished.
