Sonic Mega 8K S Guide🔗

Warning

Resin printers are TA-operated only.

8KS is a large format resin printer. Pre-configured profiles can be downloaded from here.

1. Powering On🔗

The power button is at the back of the printer on the right side.

2. Resin Preparation🔗

  1. Shake the bottle to ensure resin is homogeneous.
  2. Flip the lid up and pour slowly into the vat, keep resin level between minimum and maximum line.
  3. Inspect for debris; remove any with a plastic scraper.

Note

Keep the lid open as little as possible to prevent dust from entering the printer and to keep the fumes in the printer.

3. Starting a Print🔗

8KS lacks network and internal storage; all jobs must be loaded via USB as goo or ctb.
The USB port is located on the front. On the touchscreen home UI, tap Print and choose the file from the USB drive.

Note

Keep the screen clean; touch only with resin‑free, dry hands.

4. Monitoring🔗

The first few layers are submerged; listen for the sound of release‑film realeasing (example).

Another method is to Pause the print to lift the build plate out of resin and inspect adhesion.

As the print rises above the resin, periodically check in to visually check for missing sections.

Info

During extended prints, replenish resin as needed.
Best practice: pause the print before adding more resin.

5. Removing the Build Plate🔗

  1. Allow excess resin to drip off for a few minutes before removal.
  2. Loosen the thumbscrew, do not fully unscrew, on top of the build plate and remove the build plate by sliding forward.

Info

The 8KS includes a built‑in hanger that tilts the build plate, accelerating resin drainage.
For taller prints, this angle can cause the part to extend beyond the vat, leading to resin drips onto the machine.

6. Post Processing🔗

Follow the standard post processing steps

To remove the vat, unscrew the 2 thumb screws holding down the vat.

7. Shutdown🔗

  1. Tighten the vat with a thumb‑tight grip
  2. Place any vat cover if present.
  3. Flip the machine’s power switch to off.

8. Closing shop🔗

  • Close the extraction flap and turn off all extraction systems and lights.
  • Lock doors before leaving.

Note

If there are laser TAs remain on shift, simply close the printer exhaust flap; hand over closing duties to them.
