[Lumii DLP] Post-processing Guide

After printing with your Lumii DLP Printer, post-processing is critical to ensure durability, accuracy, and safe handling. This process includes removing the model from the building plate, washing, drying, and post-curing. Proper post-processing strengthens your models, prevents cracking, and ensures they are fully cured and safe to handle.

Always wear protective nitrile gloves when handling uncured resin to prevent skin irritation and protect against alcohol exposure during cleaning.

Removing the Model from Building Plate

1. Loosen the knobs to release the building plate from the printer.
2. Carefully remove the building plate and place it on a stable, level surface.
3. Wipe off any excess resin from the plate to prevent drips during handling.
4. Use a metal scraper to gently remove the printed model from the surface of the building plate.
   

Washing the Model

Manual Washing

1. Prepare two containers with 95% isopropyl alcohol (or clean water if using water-washable resin).
2. Rinse the model in the first container to remove excess resin.
3. Transfer to the second container for a final rinse.
4. For detailed areas, gently clean with gloved fingers or a soft brush.
   
   

Using the Washing Station

1. Fill the washing station with 95% isopropyl alcohol (or water).
2. Run the cleaning cycle for a maximum of 1-3 minutes.
3. Inspect the model after each cycle and repeat if necessary.
   

Caution: Prolonged soaking can soften the resin and damage the model.

Drying the Model

1. Ensure the model is free of any uncured resin.
2. Air dry in a shaded area for 30–60 minutes, or use an air gun for faster results.
3. If using a curing station, activate the dry mode to expedite drying.

Post-Curing the Model

1. Confirm the model is completely dry before curing.
2. Use a curing station or direct sunlight:
   • Curing Station: Place the model on the turntable, set the timer, and start the process.
   • Sunlight: Place under direct sunlight, rotating periodically for even curing.

Post-curing under sunlight may result in discoloration or uneven curing due to inconsistent exposure.
