Formlabs IBT Flex Resin Mode D'emploi page 2

IBT Flex Resin is light-curable polymer-based resin designed for the additive fabrication of
biocompatible, short-term use, removable dental appliances such as indirect bonding trays and trays
for guided restorative techniques. This Manufacturing Guide will give equipment, printing and post-
processing recommendations and requirements to ensure the correct and safe usage of this material.
Specific Manufacturing Considerations
IBT Flex Resin specifications have been validated using the hardware and parameters indicated
below. For biocompatibility compliance, validation used a dedicated resin tank, build platform,
wash unit and post-processing equipment that were not mixed with any other resins.
1. Hardware:
a. Formlabs 3D Printer: Form 3B/3B+, Form 3BL
b. Print Accessories: Formlabs Build Platform, Formlabs Stainless Steel Build Platform,
Formlabs Build Platform 2, Formlabs Build Platform 2L, Formlabs Tanks
2. Software:
a. Formlabs Preform
3. Printing Parameters:
a. Part Orientation:
• For 200 μm Print Settings: Print parts flat on the build platform without supports.
• For 100 & 50 μm Print Settings: Parts may be printed flat on the build platform without supports.
If desired, parts may be printed on supports at up to a 40° tilted angle, with the intaglio surface
facing away from the build platform.
• 50 & 200 μm Print Settings are only available on the Form 3B/3B+
b. Part Thickness: 1 mm minimum
4. Recommended Post-Processing Equipment:
a. Formlabs Validated Wash Unit: Form Wash, Form Wash L
b. Formlabs Validated Cure Unit: Form Cure, Form Cure L
A. PRINTING
1. Shake cartridge: Shake the cartridge before every print job. Color deviations and print failures
may occur if the cartridge is shaken insufficiently.
2. Set up: Insert resin cartridge into a compatible Formlabs 3D printer.
3. Printing:
a. Prepare a print job using PreForm software. Import desired part STL file.
b. Orient and generate supports if needed.
c. Send the print job to the printer.
d. Optional: If starting with an empty resin tank, save time by manually pre-filling the tank by
pouring in resin directly from the cartridge.
e. Begin print by selecting a print job from the print menu. Follow any prompts or dialogs shown
on the printer screen. The printer will automatically complete the print.
B. PART REMOVAL
Remove the build platform from the printer. To remove parts from the build platform, wedge the
part removal tool under the printed part raft, and rotate the tool. For detailed techniques visit
support.formlabs.com.
C. WASHING
Place the printed parts in a Formlabs-validated wash unit with 99% Isopropyl Alcohol (IPA).
1. Form Wash or Form Wash L:
a. Wash for 20 minutes in the wash unit, then either rinse down parts completely with fresh IPA
from a spray bottle, or soak parts in fresh IPA for 10 minutes.
b. If parts do not appear clean after washing, consider replacing used Isopropyl Alcohol with
fresh solvent.
