3Dresyn Circular RePrint Bio, Depolymerisable Circular 3D resin triggered at 80 or 150ºC

Product description

This is a 100% circular, bio-positioned 3D resin for SLA, DLP and LCD printing at 385–405 nm that prints solid parts and later depolymerises back to a reusable syrup under a controlled thermal trigger.

Two grades are described: DP80, with a warm trigger around 80 °C, and DP150, with a high-temperature trigger around 150 °C. The system is positioned for circular printing and material recovery workflows.

Application framework

Designed for use in SLA, DLP and LCD systems at 385–405 nm within industrial and R&D environments. Intended for sacrificial molds and cores, reusable tooling and jigs, and circular printing workflows requiring controlled thermal depolymerisation and material recovery.

Typical applications

• Sacrificial molds and cores for CIM/MIM, investment casting and jewelry
• Reusable tooling and jigs that can be melt-out on demand
• R&D into circular printing and material recovery workflows

Measured physical properties

• DP80 trigger around 80 °C
• DP150 trigger around 150 °C
• DP80 activation: 70–90 °C warm bath or oven, 10–60 min depending on wall thickness
• DP150 activation: 135–160 °C oven, 10–60 min
• Exposure: +10–25 % vs. a clear engineering baseline
• Storage: 15–25 °C, dry, dark
• Shelf life sealed: 12 months
• Clear to slightly amber optics
• Clear to light-amber appearance
• Low odor
• Low shrink

Functional performance characteristics

• True circular workflow: liquid → printed solid → liquid (re-print)
• Clean thermal release
• Targeted trigger temperature for process flexibility (80 °C or 150 °C)
• Compatible with common 385–405 nm printers
• Rigid-tough window
• Heat-softening near the selected trigger temperature

Processing and handling performance

• Compatible with common 385–405 nm printers
• Exposure requires re-tuning of bottom and per-layer settings
• Post-cure: standard UV flood
• Avoid extreme over-post to keep the circular pathway efficient
• Exact time/temperature depend on geometry, post-cure, and heating method
• Validate on internal coupons
• Standard PPE (gloves, goggles, coat) and ventilation
• Keep out of sunlight during mixing/printing
• Resin, a graduated beaker, and a black 250 mL bottle for light-protected handling are included

Chemical and safety characteristics

• 100% circular
• Bio-positioned
• Low odor

Testing & processing disclaimer

Exact time/temperature depend on geometry, post-cure, and heating method—validate on internal coupons. Given its advanced technical nature and the fact that effective use may require formulation-specific adjustment and controlled process development, it is offered as part of 3Dresyns proprietary resin customization services.
