Instructions:Formlabs Form 2 Resin 3D Printer (LovingCosset)

These instructions apply to the Form 2. Form 3 has slightly different procedures for installing the build plate.

Introduction

Stereolithography (SLA) printing uses a laser to cure solid parts from a liquid photopolymer resin. The build plate lowers from the top of the printer, dips into the tank, and the laser selectively cures the layer. The layer then peels back from the bottom of the tank, the build platform lifts, and the wiper mixes the resin to prepare for the next layer.

Safety

Hazards

• 3D printing resin is toxic and can be absorbed through the skin
• Resin can splash when pouring and blind the user
• 3D printing resin fumes are toxic

PPE

• Wear gloves at all times
• Wear safety goggles (full seal) when pouring resin (eg from the tank back into the cartridge)
• Wear safety glasses when removing support materials
• The Lifebreath HRV (3DP) will protect you against fumes

Avoiding Equipment Damage

• If the tank is removed before the build platform, liquid resin can drip from the build platform onto the optical surfaces inside the printer. Always remove the build platform before removing the tank. In case of spills, contact maintenance staff to clean the optical surfaces.
• Each tank has an optical surface on the bottom and top that must not get dirty. Always handle tanks from the sides - NEVER touch the bottom or top.

Housekeeping

• Clean the area of any loose support materials
• Wipe down the control panel with an IPA-moistened paper towel
• Wipe down tools and wash station mat with IPA-moistened paper towel
• Ask maintenance staff for assistance cleaning any optical surfaces (bottom and top of the tank, mirrors)
• When swapping out materials, put the tank and cartridge into the appropriately labelled tupperware bin
• If you bring your own materials, store them on the shelf below and to the left of the resin printers. Make sure they are clearly labelled

Consumables

North Forge supplies resin and invoices members at {some amount} per mL:

• Always include your name in the file name that you send to the printer.
• If you bring your own materials, include that information in the file name (ie "JohnHOwnMatl").
• Always fill out the consumables sheet beside the computer. Include the material type and amount used. All material costs the same amount.
• If the consumables sheet is missing or full, post your usage on the consumables channel on Slack and ask for the sheet to be replaced.
• If you get a "low resin" warning when trying to print, post in the consumables channel on Slack to ask for more.
• Members can bring their own resin but use North Forge tanks, in which case they will be charged {a lower amount} to account for tank wear and tear.
• Members can bring their own tank and resin, in which case they will only be charged {a much lower amount} to account for power, IPA use, and general wear and tear.

Operations

Using the Printer

Changing Resin

1. Put on PPE (gloves, goggles)
2. Remove the build plate to avoid dripping resin inside the printer
3. Remove the cartridge and unscrew the cap
4. Load a cone filter and funnel into the cartridge neck. Set aside.
5. Holding from the sides
