Using BioMed Elastic 50A Resin

Notice:

To avoid damage to equipment, check the resin tank compatibility table in Choosing the right material to confirm you are using a resin tank that is compatible with this material.

BioMed Elastic 50A Resin is a soft, elastic, medical-grade material for applications requiring comfort, biocompatibility, and transparency. This ISO 10993 and USP Class VI material is produced in an FDA-registered, ISO 13485 certified facility and can be used in applications with long-term skin and short-term mucosal membrane contact.

Printing with BioMed Elastic 50A 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.

Finishing

The Form Wash agitates the solvent bath and removes parts from the bath after a set time. Wash parts in 99% IPA according to the support article Form Wash time settings. Pay particular attention to information that affects mechanical properties or biocompatibility requirements.

If the model is hollow or has internal channels, ensure liquid resin is flushed out thoroughly from these features. Allow parts to fully dry before post-curing.

Post-curing requirements

BioMed Elastic 50A Resin requires post-curing to reach its optimal mechanical properties.

Note:

To post-cure this resin, submerge parts in a glass container of water at least 500mL in size. Parts should be fully submerged with no air bubbles on surfaces.

Refer to the support article Form Cure time and temperature settings for post-curing recommendations. If using Fast Cure, refer to the support article Fast Cure time settings.

Notice:

Follow the post-curing recommendations in the manufacturing guide for the clearest and best possible results. Improper post-curing can lead to suboptimal mechanical and biocompatibility properties.
