Workflow and Printer Settings

Validated Workflow

To achieve the specified properties as provided in the Technical Data Sheet (TDS), which can be found HERE

It is crucial to follow validated workflows. Examples of validated workflow steps include:

  1. Ensure the use of a suitable industrial DLP printer.
  2. Follow safety protocols as outlined in the safety data sheet.
  3. Properly condition and handle the resin before printing.

Printer Settings

LOCTITE 3D MED3394 SHR BK is specifically formulated for optimal performance on industrial DLP printers. Please adhere to the following recommended print parameters to ensure the best results:

  • Shake the resin bottle well before use.
  • Maintain the temperature between 20°C and 35°C.
  • Set the light intensity between 3 mW/cm² and 7 mW/cm².
