Pegasus Touch Laser 3D Printer Care



To keep the body of Pegasus clean, use microfiber cloth to wipe the outside. If you want a shine on the cover , use products specifically recommended for acrylic, e.g. Novus #1. Avoid products that contain ammonia, e.g. Windex.

Please DO NOT clean the cover with Isopropyl Alcohol (IPA) since it will cause permanent damage to the acrylic.

Never remove the build platform without first placing a 9.5"x14.5" cutting board on top of the vat to prevent resin drips.

Never remove the VAT before removing the build platform to prevent resin damage to the mirror or galvanometers.

Wipe mirrors only with a dry microfiber cloth . Never attempt to clean the galvo mirrors or the first surface 45 degree mirror with any solvents or other liquid solutions as these will leave some streaking and your print performance will degrade. You may use First Contact Polymer Solution to clean mirrors when extremely dirty. Follow all manufacturer instructions when using first contact polymer.

Do not clean the vat with isopropyl alcohol or any other chemicals. Doing so may crack the vat. Wipe it clean only with paper towels.

Removing Cured Pieces From Failed Prints



In case of a failed print, you will need to remove cured resin remnants from the build tray. Lightly run a soft rubber spatula across the bottom surface of the tray to find the pieces and dislodge them. Tweezers are never a good idea because the sharp tips can damage the VAT.

Transportation



To transport the printer, please follow the instructions below.

  • Clean excess resin from the build platform with IPA and paper towels.
  • Wrap the build platform in plastic wrap and reattach to the printer.
  • Clean the resin tray as instructed in next part, wrap the tray and put it back in the pr inter. Use a zip tie to secure the VAT holder to the magnet switch bracket to prevent it from moving during transport. If you do not secure the VAT holder, the VAT may be damaged.
  • Lower the build platform by manually turning the Z lead screw all the way down until it presses against the VAT.
  • Position the protectors or scoring cardboard over the front edges and bind in place using plastic wrap.
  • Rebox the printer and accessories in the original package as they were received.

Resin Care



Handling

  • Please wear protective gloves when handling resin. If you get any on your skin, wash thoroughly with soap and water immediately. The resin can cause mild skin irritation.
  • Never ingest resin nor use pr int parts for that purpose.
  • Never pour resin back into the original bottle to avoid contamination. Keep unused resin in the VAT or pour it out into a secondary dark bottle and store in a dark cabinet.
  • Cured resin is safe to touch and handle without gloves or other protection.
  • Refer to Appendix D: Material Safety Data for additional information.

Refilling

  • Pause the print.
  • Pour resin directly into the tray. Do not exceed the maximum fill line as it will spill and damage the printer while printing.

Spills

  • Clean up immediately before it hardens.
  • To clean printer body and mirrors: use IPA and paper towels or clean microfiber cloths.
  • Use only first contact polymer solution to clean mirrors - never clean the mirrors with solvents.

Storage

  • Always store the resin in opaque bottles or under the printer cover. Natural light will cure the resin.

Reusing

  • You may reuse the remaining resin in the tray, but do not return it to the original bottle since it may result in contamination. Keep the remaining resin in the tray under the cover .

Disposal

  • Cleaned parts and cured resin may be thrown away as normal waste. They are non-recyclable.
  • Resin in liquid form must be cured before disposal. Place the resin in a clear plastic bottle or bag and use sunlight or a UV lamp to cure.
