3D-ADD Circular RePrint DP80 (Warm-Release Additive)

Product description

DP80 enables depolymerisable printing with a warm activation window, typically ~70–90 °C. Printed parts can be reverted to a reusable liquid suitable for re-printing after simple coarse filtration.

It is designed for clarity, low odor and easy vat handling, and can be used as a modifier or as part of a re-printable formulation depending on the selected use level.

Application framework

Designed for use with SLA, DLP and LCD systems at 385–405 nm. Suitable for sacrificial molds/cores, lost-pattern workflows, educational circularity demos, and clear prototypes requiring gentle, clean removal.

Typical applications

• Sacrificial molds and cores
• Lost-pattern workflows
• Educational circularity demos
• Clear prototypes requiring gentle, clean removal

Measured physical properties

• Warm activation window: typically ~70–90 °C
• Modifier Mode: 10–20 wt% in your host resin (start at 10%)
• RePrint Mode: 40–60 wt% of the total formulation for full re-liquefaction behavior
• Mass recovery: ≥90% on 2–4 mm plates
• Recovered-liquid viscosity: within ±20% of virgin
• Re-print exposure delta: ≤25% for equivalent green strength
• Shelf life: 12 months sealed
• Storage: 15–25 °C, dry and dark

Functional performance characteristics

• Warm release (~80 °C) for gentle removal and low process stress
• High liquid recovery potential compatible with re-use
• Clarity-friendly
• Suitable for clear and lightly tinted parts
• Works on SLA/DLP/LCD (385–405 nm)
• Plug-in to open-materials resins

Processing and handling performance

• Work under low ambient light
• Add DP80 slowly into the host resin under stirring
• Temper to 40–50 °C if needed for fast homogenization
• Degas before filling the vat
• Protect from light (use black bottles or covered tanks)
• Keep your baseline z-lift/peel settings
• Increase exposure +10–25% to compensate for the additive; adjust base and per-layer times
• Use the minimum-effective UV dose needed to reach your target mechanical properties
• Heat parts to ~70–90 °C for 10–60 min depending on section thickness, post-cure level, and heating method
• As material flows, collect the liquid; coarse-filter (≈25–50 μm)
• If re-cure speed seems lower after several cycles, top-up a small dosage of Fine Tuner FT1 and re-optimize exposure
• Print the recovered liquid as usual; expect +10–25% exposure vs. virgin material
• Validate dimensional accuracy and surface quality on test coupons
• Each kit includes the product, a graduated beaker, and a black 250 mL bottle for protected handling and storage

Chemical and safety characteristics

• Low odor
• Industrial/R&D use
• Wear standard PPE
• Ensure good ventilation
• Not evaluated for implant/medical/food contact unless explicitly stated

Testing & processing disclaimer

Printer/process-dependent performance must be validated by the user. Over-post-cure can slow release kinetics. High-opacity or heavy-fill systems require tuning. 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.

Disclaimer

This material is supplied as a professional manufacturing material and is not marketed as a finished medical device. Final part performance and suitability must be validated by the user according to the intended application.
