Post-Processing a Print

Inspect the model for any visible failures. It may be helpful to pull up the stl file on a computer to compare.

Look for floating debris in the tank.

If there was no floating debris and the part looks successful, select "YES" on the touch screen.

If the part was unsuccessful, select "NO" to begin tank cleaning procedures. Refer to a separate guide.

Gloves must be worn at all times when handling uncured resin or the build plate.

Safety goggles must be worn for removing cured supports from the model, but gloves are not required

Find the correct IPA tank and place it on the table.

There is a "light" tank and a "dark" tank. The light tank is for white and clear, and the dark tank is for black resins. This prevents light parts from getting stained black during washing.

Open the lid and inspect the metal holder. There should be a basket at the bottom and a rectangular frame on top.

Push down on the latch holding the build plate in place.

Pull the build plate out of the XiP.

Rinse the part with IPA over a trash can to remove liquid resin.

Wipe the top surface of the build plate with a paper towel.

Gently place the build plate and the model in the IPA tank.

The build plate should rest on the rectangular metal frame.

Ensure that the IPA level is above the base of the build plate and the model is fully submerged.

Secure the lid in place.

If the reflective film and rotating base are still in the Nexa3D Wash+Cure, remove them.

Place the IPA tank (with the build plate inserted) on the Wash+Cure.

Ensure the Wash+Cure is set to "Wash" mode and start the timer for 10 minutes.

Multiple washes may need to be done if the resin is not completely washed off. 10 minutes is a good duration for every wash

Remove the IPA tank from the Wash+Cure and take out the build plate.

Rinse the model with more IPA and wipe the build plate with a paper towel.

Inspect the model for any liquid resin. If you see any liquid resin, or if the model feels sticky, run another wash cycle.

Use a razor blade to carefully separate a corner of the model raft from the build plate.

Use a very shallow angle when using the razor blade! Be careful not to scratch the build plate!

Once a corner is separated, use a metal scraper to slowly lift up more of the raft.

Gently work your way around the model until the model pops off the build plate.

Retrieve the magnetic dry-erase tag with the order number of the model. It should be located below the printer that the model was printed on.

Place the model on the drying shelf with the tag nearby.

Ensure the fans are turned on using the switch.

Leave the part to dry for 5-10 minutes. you may need to reorient the model to completely dry all surfaces.

Wash all surfaces of the build plate with IPA and a paper towel. Ensure the build plate is completely dry, and all resin/debris is removed.

Slide the build plate back into the printer.

Engage the latch on the top of the rail to secure the build plate in the XiP.

Check the model for any sticky surfaces or liquid resin.

If the model is sticky, place it in the IPA tank and wash it again.

If the model is still wet from IPA, let it dry longer.

The model must be completely dry before moving on to curing!

Place the reflective sheet and the rotating base on the Wash+Cure platform.

Ensure the rotating base seats into the exposed gear at the center.

Place the model (with supports intact) on the rotating base.

Place the UV cover on top of the Wash+Cure.

Ensure the Wash+Cure is set to "Cure" and set the timer. Push the dial inwards to start the curing process.

Information about curing times can be found here

Curing can cause thin parts to warp. Check on the model every 3-5 minutes. If discoloration or warping occurs, you can stop the curing process and move on.

Take the part out of the Nexa3D Cure+Wash and place it on the silicone post-processing mat.

Using flush cutters, start cutting away at the support structures. Cut close to the model surface, but be careful not to damage the model.

Once all accessible support structures are severed from the model, begin cutting away larger chunks of support.

After all of the support structure is removed, inspect the model for any leftover bits of support.

Use the flush cutters to clean up the surface of the model.

The support will leave an uneven finish on the model. It is best to avoid digging at the small bumps left from the support because you could damage the model.

Wipe off the dry-erase tag and return it beneath the XiP.

Clean up all resin and support structures from the post-processing area.

Return the IPA tank next to the post-processing area.

Print out the label for the order on the Papercut page.

Place the model in a bag and apply the label to the bag.

Looking at the order number, place the model in the correct bin.

The order number sequence is marked on the bins.

Mark the order as "Ready for Pick-Up."

In the notes section of the order, indicate the letter of the bin the model was placed in.

Post-processing is complete.
