Preparation and Setup | 17

5. Using the Form Cure
5.1 Operational Environment
Operate the Form Cure in a well-ventilated room with a temperature of 18–28 °C (64–82 °F).
For optimal performance, do not exceed this range.

5.2 Post-Curing
5.2.1 Insert Washed and Dried Prints
Fully dry all solvent off of printed parts after
washing. Check all surfaces, because curing
non-dried parts may trap solvent inside the
part, prevent parts from strengthening, and
affect quality. Once parts are dry, lift the cover,
then distribute parts on the round turntable.
Place parts with the most even spacing
possible to allow light and heat to reach all
areas. Gently close the cover.

The Form Cure contains a heater to

WARNING
enable post-curing. Take care when
inserting and removing parts from the
Form Cure, because the metal turntable
may be hot.

5.2.2 Set Post-Cure Time and Temperature

Turn the knob to navigate the display menu. Press the knob to select a feature or setting.
Select the time and temperature, and then select Start. The LEDs will activate and the timer
will start once the heater has reached the target temperature. Once a cure cycle has started,
use the display or open the cover to pause post-curing.
See support.formlabs.com or 5.4 Time and Temperature Settings for specific post-cure
settings for each resin type.

The printed part must be in the Form Cure while it heats. If the part is not placed in
NOTICE
the Form Cure until preheating is complete, it may cause cracking.

18
5.2.3 Collect Prints
When the cure cycle completes, the LEDs and heater will turn off. Lift the cover and remove
parts. Use caution; the metal turntable may be hot.
5.2.4 Part Finishing
Once parts are post-cured, use the flush cutters that come in your Finish Kit or Form
Wash 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.

Wear safety glasses to protect eyes from dislodged fragments of supports.

CAUTION

In addition to removing supports, use sanding, polishing, priming, or painting to improve

presentation, or use other equipment to create molds from printed parts.

5.3 Considerations for Specific Geometries

Consider the specific geometry of each part when starting the post-cure cycle. Modify the post-cure
process for parts that are large or long, have dense support structures, or have thick or thin features.
5.3.1 Remove Dense Supports
Some parts require more dense or thicker support structures. These can inadvertently block
light from reaching some part surfaces during post-curing. The Form Cure helps ensure even
post-curing by rotating the part during the cure cycle and exposing the part to light from all
directions, including underneath the turntable. Remove some supports, only as needed, to
ensure that light can easily reach all part surfaces. Leave some supports in place whenever
possible to prevent features from warping during post-curing.
5.3.2 Plan for Large or Long Parts
The Form Cure turntable has a diameter of 19.3 cm (7.6 in), and the maximum part height that
can be post-cured in the Form Cure is 18.5 cm (7.3 in). Most parts should be post-cured before
removing support structures to preserve their shape and prevent warping. While some parts
may fit on the turntable more easily without supports, long or tall prints may require special
arrangements to stand on the turntable without support. Consider the part dimensions when
designing the support structures or planning the post-cure steps.
5.3.3 Add Time for Thick Parts
Large or thick parts may require a longer post-curing time or higher temperatures because the
part takes longer to heat. Light alone cannot post-cure beyond the surface of the part, which
is one advantage of the Form Cure heating functionality. When post-curing thick geometries,
warm the part before post-curing and allow extra time for the Form Cure to preheat to the
target temperature before starting the post-cure lights and timer.
5.3.4 Add Supports for Thin Features
Warping during post-curing may occur if a part is especially thin, inadequately supported, or unevenly
exposed to light. The Form Cure helps prevent warping by rotating the part during the cure cycle and
by exposing the part to light from all directions, including underneath the turntable. Use support settings
or manual editing to design sufficient supports so that thin features do not warp during post-curing.
In the case of a thin, flat, sheet-like object, placing the part directly on the turntable may offer
the best support during post-curing.

5.4 Time and Temperature Settings
For the best results, use the recommended time and temperature settings tested specifically
for use with the Form Cure.
Each material’s print settings are designed and refined to print parts successfully at optimal
speeds. Additional post-curing further improves the functional properties of the materials.
Post-curing exposes parts to light and heat and strengthens crosslinks in the polymer structure,
improving the parts’ strength, stiffness, and temperature resistance. Due to the increased number
of bonds the material becomes more tightly packed and will shrink slightly. Each material’s print
settings are designed to account for the expected shrinkage during printing and post-curing.
Although using a higher temperature for post-curing results in a faster post-cure, a higher
temperature setting may also cause some materials to warp, depending on the part geometry
and features. When choosing to modify the recommended post-cure settings, the material must
be able to withstand the temperature and maintain a stable material structure.
Formlabs resins are designed for printing and post-curing with 405 nm light.

1 The recommended post-cure settings achieve close-to-maximum mechanical performance and minimize the post-cure
time. The full post-cure settings achieve the maximum mechanical properties and require significantly more time. Use
full post-cure settings when using materials for functional applications.

2 For parts printed with Durable Resin, the tensile modulus continues to increase steadily throughout the first hour of post-
curing. There is only one proposed post-curing setting.
3 There are several post-curing options for High Temp v2. To achieve the highest HDT, also post-cure the parts in a non-
food oven. Refer also to the technical data sheet to understand how different options affect mechanical properties, and
choose the post-cure option that is best suited to the intended application.

4 There is no significant gain in properties after 15 minutes. There is only one recommended post-curing time.
5 Does not require post-curing. After washing, allow parts to fully dry before firing/casting.
6 This cure setting ensures that parts achieve both biocompatibility and optimum mechanical properties.
7 Fill a glass container with glycerin. Preheat the glycerin to 80 °C in the Form Cure. Use heat resistant silicone tongs to
fully submerge the assembled denture in the glycerin, leaving the container inside the Form Cure. Cure for 30 minutes.
After the first 30 minute post-cure, flip the denture to the opposite side. Post-cure again for 30 minutes.

The glycerin and denture at 80 °C are hot. Use heat resistant silicone tongs to insert and remove the denture from
the curing chamber.
WARNING

8 Cure for 4 hours to increase the part strength. After curing, follow the Castable Resin: Jewelry Pattern Burnout Process
found on support.formlabs.com. Increasing the cure time may improve casting results, particularly for thicker parts, though
casting success depends more on the part geometry and casting process. Testing results show no disadvantages for
increasing cure time.

These settings will be updated periodically. Always refer to formlabs.com/cure-support for the
most updated information about post-curing printed parts with the Form Cure.

5.5 Device Management

6.2 Inspection Tasks Between Post-Cure Cycles

6.2.1 Turntable Maintenance
The Form Cure relies on the turntable’s rotation to expose part surfaces to even amounts of
light and heat. The turntable must have sufficient clearance to continue rotating.
Periodically lift the turntable to inspect underneath it for small pieces of cured resin. Remove particles of
cured resin from above and below the turntable to ensure the turntable can rotate without interruption.
Clean the turntable and the surface underneath as needed. Use IPA to clean the turntable
or the base if necessary, and allow IPA to fully evaporate before starting a post-cure cycle.

Maintenance | 23
6.2.2 Dry Parts and Keep Equipment Clean
Completely wash and dry all parts before post-curing in the Form Cure. Do not operate the
Form Cure with uncured resin, partially cured resin, or other liquids on the turntable.

6.3 Monthly Inspection and Maintenance Tasks

6.3.1 Interior Surface Maintenance
The internal surfaces of the Form Cure are covered in a reflective coating that reflects the
light from the 405 nm LEDs and ensures that parts post-cure evenly. If the reflective coating
is damaged or covered, parts may not post-cure properly.
Visually inspect the internal surfaces of the Form Cure for traces of resin, cracks, or
other damage. Resin will harden during the cure cycle. Cured resin blocks light and
must be removed.
If parts are washed but not fully dry before post-curing, certain washing solvents, such as
tripropylene monomethyl ether (TPM), may evaporate and form deposits on the interior surfaces
of the Form Cure. These deposits will cloud the reflective coating and prevent parts from post-
curing properly. Clean the reflective coating as needed. Use IPA to clean the reflective coating
and allow IPA to fully evaporate before starting a post-cure cycle.
6.3.2 Light Diffuser Maintenance
The 405 nm and white secondary LEDs in the Form Cure are covered by frosted light diffusing
panels. These light diffusers spread the light from the LEDs and ensure that parts post-cure
evenly. If the light diffusers are damaged or covered, parts may not post-cure properly.
Visually inspect the light diffusers for traces of resin, cracks, or other damage. Resin will
harden during the cure cycle. Cured resin blocks light and must be removed. If parts are
washed but not fully dry before post-curing, certain part washing solvents, such as tripropylene
monomethyl ether (TPM), may evaporate and form deposits on the interior surfaces of the Form
Cure. These deposits will coat the light diffusers and prevent parts from post-curing properly.
Clean the light diffusers as needed. Use IPA to clean the light diffusers and allow IPA to fully
evaporate before starting a post-cure cycle.

6.4 Periodic Inspection and Maintenance Tasks

6.4.1 Inspect the Cover
Visually inspect the cover for traces of resin, cracks, or other damage. Clean the cover with a non-
abrasive microfiber cloth and soapy water or a general purpose cleaner, such as glass cleaner.
6.4.2 Inspect the Display
Visually inspect the display for any traces of resin. Check that the knob turns easily and that
the display responds to inputs. Clean the display with a non-abrasive microfiber cloth and
general purpose cleaner, such as glass cleaner.
