3Dresyn LMM RSB1 WD, Water Debindable Reactive Solid Binder for water debinding and sintering of Metals and Ceramics printed by Lithography-based Metal Manufacturing LMM

Product description

3Dresyn® LMM RSB1 WD is a universal Water Debindable Reactive Solid Binder (spreadable butter-like paste at room temperature <30ºC) developed for water debinding and sintering of metals and ceramics printed by Lithography-based Metal Manufacturing (LMM).

Application framework

Designed for use in lithography-based additive manufacturing systems within controlled professional environments. Suitable for the preparation of highly filled feedstocks and slurries for ceramic, metal, polymer and exotic material processing with water-based debinding workflows.

Typical applications

• LMM feedstock preparation for metals and ceramics
• Water-debindable binder systems for advanced manufacturing
• High powder loading slurries for technical materials
• Processing of exotic powders including nanowires and microfibers
• Eco-friendly debinding and sintering workflows

Measured mechanical properties

• Melting temperature (Tm): 33–36 °C (internal method)
• Solid paste behavior at room temperature (<30 °C)
• Pseudoplastic rheology (non-flowing at rest, flowing upon shear) (rheology internal method)
• Process-dependent viscosity upon melting (Brookfield)

Functional performance characteristics

• Universal water-debindable reactive solid binder system
• Ideal for dispersing, debinding and sintering ceramics, metals, polymers and exotic powders without defects
• Excellent dispersability and flow of micron and submicron powders (including nanowires, microfibers, etc.)
• Powder additions up to 60% volume concentrations (lower for nanoparticles, nanowires and microfibers)
• Lower wetting and flow than 3Dresyn LMM RSB1 SD at high powder loadings
• Partial water solubility enabling fast debinding without defects or cracking
• Complementary thermally debindable fraction ensuring structural integrity
• Controlled and reproducible process shrinkage depending on powder loading
• Minimum expansion coefficient to prevent micro-fractures
• Solid at room temperature, excellent flow upon heating
• Very high resolution of 20 microns in final products
• Suitable for ceramic, metal, polymer and exotic material LMM printing
• Eco-friendly processing route
• Organo-tin free formulation

Processing and handling performance

• Photoreactive solid binder with pseudoplastic behavior
• Low melting temperature range enabling easy processing
• Excellent flow after melting and before printing
• Compatible with high powder loading mixing processes

Recommended feedstock or slurry mixing

• Add the binder and your chosen ceramic, metal, or polymer powder with powder volume concentrations of up to 50–60% to a powder kneader mixer (or similar) at 50ºC for 30 minutes

Recommended debinding and sintering process of green parts

1. First step: water debinding at 65ºC for 5 hours
2. Second step: thermal debinding:
   1. Insert flask in the preheated oven at 65ºC
   2. Ramp 1–2ºC/min up to 250ºC
   3. Hold at 250ºC for 60 minutes
   4. Ramp 1–2ºC/min up to 450ºC
   5. Hold at 450ºC for 30 minutes
   6. Ramp 2–5ºC/min up to sintering temperature
   7. Hold at sintering temperature for 180 minutes
   8. Ramp −2ºC/min down

Testing & processing disclaimer
