RPU 130
RPU 130 is a strong, tough, and heat-resistant material with an impact resistance of 76 J/m and a heat deflection temperature of 119°C. Made with 30% bio-based Susterra® propanediol, it balances performance and sustainability. Its properties make it comparable to unfilled thermoplastics like nylon and polypropylene.
- Not compatible with the M1 printer; compatible with M2, M3, M3 Max and L1 printers.
- M2 printer requires a C5 heated cassette and C5 connector cable.
- Requires a Cox Dual-Drive Dispenser.
- Smart Part Washer compatible with DPM (di(propylene glycol) methyl ether; CAS 34590-94-8; 99+% purity). Not compatible with VF 1 solvent.
- Sustainability: 29.5% plant-based material.
- U.S. customers only: Contact Carbon Support to complete one-time only EPA regulatory paperwork to purchase RPU 130.

- If attempting feature sizes smaller than the recommended feature sizes, note the following for RPU 130:
- Thin walls are especially susceptible to deformation after washing with DPM solvent. Handle thin features with extra care in the green state before baking.
- Holes and engravings (negative features) may be difficult to fully clean due to the high viscosity of the liquid resin.
Suction and resin flow forces will be higher at the beginning of a print as the cassette is still heating up.
- Orient parts to keep thin/delicate features later in the print and/or
Print Stats & Project Analysis can be run in the printer UI for estimation purposes with or without the C5 cassette installed.
- Access the Print Controls tab.
- Under the Cassettes pull-down menu, select the M2C5 option.
- Run analysis for estimation purposes on the Project analysis tab.
Please Note:
- The C5 cassette must be installed for printing.
- Selecting a cassette type for analysis will not effect the cassette type you ultimately print with.
RPU 130 resin may experience reversible crystallization at lower temperatures, or even solidification in extreme cold. During shipping, resin may have been kept at low temperatures and cartridges must be properly incubated before use.
Before use, incubate cartridges:
- Place one or more cartridges directly into oven or incubator.
- For multiple cartridges, make sure cartridges are evenly spaced for even heating.
- Set the time and temperature for 3 hrs at 40°C (104°F).
- Run oven or incubator to melt crystals.
- Carefully remove cartridges from oven or incubator.
- Mark cartridge as thawed on the label. (available on North American cartridges only)
- Once incubated, cartridges may be stored up to one week prior to use. Early incubation is not recommended as recrystallization may occur in long-term storage.
Oven/incubator
The same oven used for thermal curing can be used to incubate cartridges, or you can utilize a dedicated incubator for this purpose.
Cartridge spacing
For multiple cartridges, make sure they are spaced for even heating.
Mark cartridge
In North America only: Mark cartridge as thawed on the label when incubation complete.
On M2 printers, RPU 130 requires the use of a heated cassette, type C5, and a C5 cable. The M3 and L1 printers have built-in heating components to accommodate RPU 130.
For more information about the C5 Cassette, please see C5 Cassette.
RPU 130 will develop a film on the surface of the liquid resin after dispensing.
This is normal and will not affect the print.
Reversible crystallization in RPU 130 will appear as a result of storage below recommended temperatures.
When dispensing, look for signs of crystallization and follow mitigation steps.
How to identify
- Reversible crystallization appears as small spherical defects in the liquid resin.
- In rare cases, extreme cold can lead to solidification.
How to mitigate
- Mark cartridges as thawed on the label.
- Washing on platform strongly recommended to prevent warping.
- Wash parts as soon as possible after printing for best results.
- Expect more touch-up if parts are waiting for washing. This is especially true for overnight prints.
A blue sheen and film on parts before washing is normal. If blue sheen remains after washing:
- Further touch up of parts via swabbing may reduce the surface finish inconsistency.
- The blue sheen is surface-only and will not affect material properties.
Blue sheen on unwashed parts
Blue sheen on parts after washing
- Washing parts on platform recommended.
- Washing multiple parts off platform will lead to scratching in an orbital wash.
- Allow parts to fully dry before handling.
- Air dry on platform.
- Or dry more quickly by utilizing the compressed air cabinet.
Washing parts on the platform is strongly recommended to prevent solvent warping.
RPU 130 is less susceptible to sagging than other resins during thermal curing.
