Use Formlabs Castable Wax Resin to produce highly detailed jewelry by casting parts through direct investment casting with minimal part finishing (no post-cure required). Castable Wax prints are strong enough to use for prototyping and fitting before production.

A 20% wax-filled material, Castable Wax Resin prints delicate models with ease. Parts printed in Castable Wax are ready to cast after washing without post-curing for fast, clean burnout and a streamlined casting process.

Understand the step-by-step workflow, recommendations, burnout schedules, and special considerations for designing models, printing, preparing investments, and casting successfully with Castable Wax Resin.

Castable Wax Resin is an acrylate photopolymer formulated with liquid wax to enable a burnout process similar to a traditional wax schedule.

Castable Wax Resin prints parts with high mechanical strength in their green state when compared to parts printed in Castable, which requires post-curing. As a result of the high strength, Castable Wax is particularly suitable for patterns with delicate features and high surface detail requirements.

Casting is both a skill and an art form. The design of the piece to be cast is as important as the material properties for successful results. Pay attention to the design of individual features, the flow of material in the investment, and the printing configuration.

When choosing a casting resin, take the casting properties of each material into consideration. For smaller parts or wire filigree, use Castable Wax Resin. For medium to heavy jewelry or small engineering components, use True Cast Resin. For larger investment casting, use Clear Cast Resin.

Install or update PreForm, then set up the next print job.

To prepare a model for printing in PreForm:

1. Open a model.
2. Select the resin, resin version, and the desired layer thickness.
3. Orient to preserve fine details.
4. Generate supports.
5. Send the print job to the printer.

The PreForm print settings for Castable Wax Resin are optimized for printing jewelry and quality cast parts, with a focus on achieving the features and detail that matter to jewelers.

Open Mode on the Form 2 must be toggled off to print with Castable Wax Resin.

Shake the resin cartridge and mix resin in the resin tank to agitate Castable Wax Resin before printing. Mix the resin regularly to maintain or restore expected resin performance.

Der Form Wash bewegt das Lösungsmittelbad und entnimmt die Teile nach der vorgegebenen Zeit. Waschen Sie die Teile gemäß dem Supportartikel Zeiteinstellungen des Form Wash.

Stellen Sie sicher, dass sich der IPA vor dem Guss vollständig verflüchtigt hat, da er die Einbettmasse beeinträchtigen und zu Lochfraß führen kann. Die besten Ergebnisse, insbesondere bei Druckteilen mit internen Kanälen und Hohlräumen, erzielen Sie, wenn Sie die Druckteile mit reinem IPA waschen und anschließend mithilfe von Druckluft trocknen.

No post-curing is required for Castable Wax parts. While post-curing Castable Wax parts should not affect castability, post-curing may shrink parts slightly (by less than 1%), which can cause distortion.
