Inspection Tasks Between Prints; Monthly Inspection And Maintenance Tasks - formlabs Form 2 Installation And Usage Instructions

3. Apply 1-2 full sprays of NOVUS Plastic Clean & Shine No. 1 to the clear acrylic
tank window, located on the underside of the resin tank.
4. Use a clean microfiber cloth to wipe, using long, sweeping strokes top to
bottom and across the tank window.
5. Fold the microfiber cloth after each swipe to prevent dust and debris from
scratching the acrylic.
6. Check the tank window again using a secondary light source. Repeat cleaning
as necessary to achieve a crystal clear tank window.
6.2.5 Automatic Resin Handling System
For detailed guidance and visual assistance, search on support.formlabs.com.
To replace the cartridge:
1. Press the vent cap closed.
2. Hold the cartridge handle and lift to remove from the Form 2.
Store the cartridge upright with the valve cover installed to protect storage
surfaces from resin.

Inspection Tasks Between Prints

6.3.1 Inspect the Bite Valve
The bite valve is located under the resin cartridge. This flexible seal regulates
resin dispensing. Resin flows out of the opening in the center of the bite valve
when the cartridge dispense arm squeezes the valve open. When switching to
a different resin cartridge, inspect the bite valve for any cured resin or damage.
6.3.2 Inspect the Resin Tank
See 6.2 Planned Maintenance Procedures.
6.3.3 Changing Resin Types Between Prints
When changing resin types, always change both the tank and the cartridge.
Remove the cartridge before removing the tank to prevent the cartridge valve
from dripping resin into the printer. See 6.2.2 Maintenance for Resin Tanks and
6.2.5 Automatic Resin Handling System.

Monthly Inspection and Maintenance Tasks

6.4.1 Maintain the LevelSense Board
The LevelSense board is the black panel located behind the resin tank at the
base of the Z tower. The LevelSense board measures and regulates the refill
rate of the resin in the tank. Resin contamination or damage on the board can
affect the accuracy of measurements and may lead to problems with printing.
26
To clean a contaminated LevelSense board:
1. Apply a small amount of clean IPA to a paper towel.
2. Wipe the board to clean off any resin contamination.
Avoid IPA or resin contamination on the silver, button-shaped thermopile.
The thermopile is an infrared (IR) sensor located on the lower right corner
NOTICE
of the LevelSense board and senses resin temperature. If the thermopile is
contaminated, contact Formlabs or an authorized reseller.
If the LevelSense board is damaged with scratches and/or dents, contact
Formlabs or an authorized reseller. Include a well-lit, focused photo of the
damaged LevelSense board in the request.
6.4.2 Inspecting Resin Tank and Resin Tank LT Exterior
See 6.2 Planned Maintenance Procedures.
6.4.3 Protect the ID Chips on the Resin Tank and Resin Cartridge
ID (identification) chips on resin tanks and resin cartridges detect, track, and match
the resin type in the tank with the proper resin cartridge. The ID chip is on the
underside of each tank frame and on the bottom of the cartridge near the bite
valve. Protect the ID chips, the tank carrier, the tank spring fingers, and the cartridge
spring fingers from resin contamination or damage. Cured resin or contamination
prevents the Form 2 from properly identifying a cartridge or resin tank during
insertion or use. Avoid exposing the cartridge ID chip, the resin tank ID chip, the
tank carrier, and the tank carrier fingers to liquid resin
To remove resin from the ID chip or spring fingers:
1. Apply a small amount of clean IPA to the tip of a cotton swab.
2. Rub the tip onto the two silver pads on the ID chip - or onto and around the
spring fingers - until the cured resin or contamination has dissolved completely.
Unless specifically advised, avoid getting IPA on the resin tank or cartridge.
Ensure that any IPA on the ID chip dries completely before resuming use.
NOTICE
6.4.4 Cleaning the Glass Optical Window
Remove the build platform, resin tank, and wiper to access the glass optical
window. The glass optical window is a part of the printer's optical surfaces and
sits below the resin tank. Any contamination, dust, or debris on the printer's
optical surfaces can cause the laser light to diffuse or weaken, resulting in print
failures. If you notice dust or contamination on the underside of the optical
window, contact Formlabs or an authorized reseller for additional instructions.
