MATERIAL PROPERTIESThe full suite of mechanical properties are given per ASTM and ISO standards where applicable. In addition, properties suchas flammability, dielectric properties, and 24 hour water absorption are given. This allows for better understanding of thematerial capability to aid in design decisions for the material. All parts are conditioned per ASTM recommended standards
for a minimum of 40 hours at 23 °C, 50% RH.
Solid material properties reported were printed along the vertical axis (ZY-orientation). Figure 4 material properties are
relatively uniform across print orientations, as detailed in the following section on Isotropic Properties. Because of this,parts do not need to be oriented in a particular direction to exhibit these properties.

Figure 4 RUBBER-65A BLKLONG TERM ENVIRONMENTAL STABILITY
Figure 4 RUBBER-65A BLK is engineered to give long term environmental UV and humidity stability. This means the material istested for the ability to retain a high percent of the initial mechanical properties over a given period of time. This provides real
design conditions to consider for the application or part. Actual data value is on Y-axis, and data points are % of initial value.

INDOOR STABILITY: Tested per ASTM D4329 standard method.

Figure 4 RUBBER-65A BLKBIOCOMPATIBILITY STATEMENT
Figure 4® RUBBER-65A BLK test coupons printed and processed according to the post processing instructions below were
provided to an external biological testing laboratory for evaluation in accordance with ISO 10993-5, Biological evaluation of
medical devices - Part 5: Tests for in vitro cytotoxicity, and ISO 10993-10, Biological evaluation of medical devices - Part 10: Tests for
irritation and skin sensitization (GPMT). The test results indicate that Figure 4 RUBBER-65A BLK has passed the requirements forbiocompatibility according to the above tests.
It is the responsibility of each customer to determine that its use of Figure 4 RUBBER-65A BLK material is safe, lawful andtechnically suitable to the customer’s intended applications. Customers should conduct their own testing to ensure that this is
the case. Because of possible changes in the law and in regulations, as well as possible changes in these materials, 3D Systems
cannot guarantee that the status of these materials will remain unchanged or that it will qualify as biocompatible in any
particular use. Therefore, 3D Systems recommends that customers continuing to use these materials verify their status on aperiodic basis.

MIXING INSTRUCTIONSThis material has a pigment that settles very slowly over time before printing. For best results mix material in the bottle:
1 kg bottle for Figure 4 Standalone•

Roll bottle for 1 hour on 3D Systems LC-3D Mixer for first use•

Roll for 10 minutes before subsequent uses

2.5 kg cartridge for Figure 4 Modular•

Vigorously shake the bottle for 2 minutes before installing cartridge

Use the Resin Mixer to stir material in the tray for 30 seconds between print jobs.

MANUAL CLEANING INSTRUCTIONS•Manual cleaning with 2 containers of IPA (wash and rinse)•

Clean in ‘wash’ IPA for 2.5 minutes while agitating part•

Rinse in ‘clean’ IPA for 2.5 minutes while agitating part•

DO NOT EXCEED more than 5 minutes total exposure to IPA to preserve mechanical properties•

Manual agitation and/or a soft brush can be used to aid cleaning•

Refresh IPA when cleaning becomes ineffective
