2. Introduction
2.1 Intended Use
The Form 2 is a commercial, precision tool intended for use in the additive
manufacture of end-user supplied designs from photopolymer resin. The final
performance characteristics of cured photopolymer resin may vary according to
your compliance with the instructions for use, application, operating conditions,
material combined with, end use, or other factors.
In some cases, the additive manufacturing process may inherently result in
variable performance characteristics between manufacturing runs or within
a specific part. Such variances may not be apparent and may result in un-
expected defects in additively fabricated parts.
You shall independently verify the suitability of additive manufacturing, stere-
olithography, the Form 2, and any specific designs or materials employed for
the application and intended purpose before use. In no event shall Formlabs
be liable for any loss, death, or bodily injury that you suer, or that you cause to
any third party, in connection with your use of Formlabs products. To the fullest
extent legally permitted Formlabs EXPRESSLY DISCLAIMS ANY IMPLIED OR EX-
PLICIT WARRANTY OF FITNESS for a particular usage, the particular nature and
circumstances of said usage being unforeseen and unforeseeable to Formlabs.
Formlabs is not a manufacturer of medical devices. Formlabs provides tools and
materials that may be used in many applications, but makes no claims as to the
safety or eectiveness of any specific devices made using Formlabs products.
Certain Formlabs products, such as those commonly known in the industry as
“biocompatible” resins, have been engineered to comply with relevant industry
standards. The specific standards and most relevant technical specifications
may be identified within the technical data sheets and have been tested ac-
cording to relevant testing protocols for those standards and specifications.
Biocompatible resins are a speciality product, developed for use by medical
professionals, and should be used in accordance with the instructions for use.
Do not modify – The Form 2 is intended for use as-is. Modifying the printer
without explicit approval and directions from Formlabs will invalidate your
warranty, and could potentially ruin the machine and cause you bodily harm.

thealcohol bath and removes parts from the bath after a set time.
•
A two step process will help isopropyl alcohol (IPA) last longer. To use the
Finish Kit:
° Fill two rinse buckets with IPA.
° Open the first rinse bucket and place the part(s) in the alcohol bath.
CAUTION
° Use the rinse basket to shake the part(s) for 30 seconds.
° Close the rinse bucket’s lid and let the part(s) soak for approximately half
the total recommended time.
°
Move the part(s) to the second rinse bucket, then agitate and soak the
part(s) for the remaining time.
IPA is flammable. Keep the lids closed, and keep out of the reach of children.
5.3.4 Finish Your Print
Some resin types require post-curing, and the recommended time and
temperature settings vary for each material. Post-curing is optional for most use
cases for Formlabs Standard Resins. See support.formlabs.com.
Once parts are dry, use the flush cutters that come in your Finish Kit to carefully cut the
supports attached to the part(s). Supports can also be removed before post-curing,
but parts may warp under exposure to light and heat without structural support.
You can sand support marks and polish your parts for a smooth finish.
5.4 Device Management
5.4.1 Connecting to the Form 2 with Dashboard
Dashboard (formlabs.com/dashboard) allows you to remotely monitor your Form
2 printers, track material usage, and explore past and future Formlabs purchases.

The Z Fine Tuning setting changes the “Z Oset” value to adjust the distance
between the build platform and the bottom of the resin tank.
The X/Y Fine Tuning option adjusts the scaling factor in the printer’s X and Y axes.
5.4.4 Checking and Maintaining the Resin Temperature
The Form 2 heats resin to a set temperature before starting. Resin is heated
from the metal tank carrier below the resin tank, and the resin temperature is
sensed by an infrared sensor behind the resin tank. The Form 2 automatically
pre-heats and maintains a consistent resin temperature before and between
print jobs. View the resin tank’s current temperature on the Printer tab of
theForm 2’s touchscreen
The tank carrier acts as a heating element and can become very hot
during the printing process. If the resin tank is removed immediately
after printing, do not touch the tank carrier until the temperature reaches
room temperature.
5.4.5 Using Sleep Mode or Powering Off the Form 2
Put the printer into Sleep Mode to deactivate the screen between prints. Turn o
the Form 2 completely when moving or storing the printer and to conserve power.

6.3 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 dierent 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.
6.4 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
aect the accuracy of measurements and may lead to problems with printing.
NOTICE
To clean a contaminated LevelSense board:
1. Apply a small amount of clean IPA to a paper towel.
2. Wipe the board to clean o 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
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.
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 diuse 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.

floating in the resin tank
Model orientation, layout,
and/or support issues
A print that has been
paused for a long time
An older resin tank
A loose build platform
Contaminated optical
surfaces
Consider the following:
• Check the model in PreForm.
• Check for pauses in printing.
• Check the resin tank for debris
or damage.
• Check cleanliness of optical surfaces.
• Check the build platform’s stability.
Non-Adherence
Prints either partially
attached to or
completely non-existent
on the build platform
Printing without supports
The first layer of the part
on the build platform is
too small to withstand
peel forces.
Debris/clouding/damage
in resin tank
Contaminated optical
surfaces
Build platform height
requires adjustment
Consider the following:
• Print with a base and supports.
• Check the print’s surface area.
• Check the resin tank for debris
or damage.
• Check cleanliness of optical surfaces.
• Check the build platform height.
• Decrease (“-”) the Z Oset value to
lower the build platform closer to the
resin tank bottom.
Overcompression
The base printed onto
the build platform is
thinner than expected
and/or very dicult
to remove.
The initial layers fail to cure
properly, due to insucient
space between the build
platform and the elastic
layer in the resin tank.
Consider the following:
• Increase the base height in PreForm’s
advanced settings.
• Check the build platform’s height.
• Increase (“+”) the Z Oset value to
raise the build platform further away
from the resin tank bottom. Raising the
build platform provides more space for
the base to build.
Ragging
Cured or partially cured
resin forms thin, shelf-
like structures that hang
horizontally from a print
or
Rashing
A rough - uneven or
bumpy - surface texture
forms on one or both
sides of an otherwise
successful print.
Diused laser light
spreads the cure area
beyond the appropriate
limits for each layer out-
line, due to:
Expired resin;
Debris/clouding/damage
in the resin tank;
Contaminated optical
surfaces; or,
Restricted resin flow due
to improper model ori-
entation or overly dense
supports
Consider the following:
• Check the resin’s shelf life.
• Check the resin tank for debris
or damage.
• Check cleanliness of optical surfaces.
• Check for restricted resin flow.
