RPU 130
Overview
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.
Notes
- 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.

Design
- 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.
Digital Prep
Stability Supports
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
- Utilize more stability supports on thin/delicate features.
M2 Printer Project Estimates
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.
Thermal Processing
Some resins may crystallize or freeze at lower temperatures requiring a thermal processing step, also known as incubation, prior to dispensing.
Reference this downloadable PDF for instructions.
Dispensing
C5 Cassette
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.
Film on Surface
RPU 130 will develop a film on the surface of the liquid resin after dispensing.
This is normal and will not affect the print.
Washing
- 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.
Blue Sheen and Film
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.

Scratches
- 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.
Warping
Washing parts on the platform is strongly recommended to prevent solvent warping.
Curing
RPU 130 is less susceptible to sagging than other resins during thermal curing.
