3Dresyn Perfect Cast LPP for Low Power SLA, DLP & LCD Printers

3Dresyn® Perfect Cast LPP is a castable photopolymer formulation specifically developed for direct investment casting applications using low power SLA, DLP and LCD printers. The material is engineered for high detail reproduction, clean burnout behavior and reliable casting performance in professional workflows.

Designed for use in vat photopolymerization systems (SLA, DLP and LCD) including low power and multicolor LCD printers. Suitable for direct casting workflows using standard investment materials under controlled laboratory or production environments.

• Direct investment casting (DC)
• Jewelry casting patterns
• Dental casting applications
• High-detail micro-casting components

• Density: 0.90–1.20 g/cm³, depending on formulation and, where applicable, selected version (ISO 1675)
• Printing shrinkage: no measurable dimensional shrinkage after calibration under validated processing conditions
• Colors: magenta, cyan, yellow, natural white
• Very low viscosity: <30 mPas at 23°C ± 2°C (ISO 3219)

• No shrinkage during printing
• No expansion during burnout
• Excellent dimensional precision and fine detail resolution
• Negligible residual ash content (<0.0001%) (ISO 3451-1)
• Clean burnout even with standard or low-cost gypsum investments

• Optimized for low power printers
• Faster printing speed compared to Perfect Cast HPP
• Excellent burnout behavior without defects or residues
• No post-curing required
• Stable color dispersion without sedimentation over time

• Printing technologies: SLA, DLP and LCD
• Compatible with most commercial systems
• Water cleanable (no isopropanol required)
• Monomer-free formulation as supplied
• Increased resin tank durability
• Organo-tin free formulation

• Insert flask in preheated oven at 200 °C
• Ramp 2 °C/min up to 550 °C
• Hold at 550 °C for 30 minutes
• Ramp 2 °C/min up to 720 °C
• Hold at 720 °C for 120 minutes
• Ramp −2 °C/min down to 640 °C
• Cast molten metal using centrifuge or vacuum casting system

Material performance depends on printer type, exposure conditions, investment material, burnout cycle and casting process. Parameters must be validated by the user for each specific workflow.

• Optimized for low power SLA/DLP/LCD printers
• Clean burnout with negligible ash content
• Water washable workflow (no IPA required)
• High resolution and dimensional precision
• Fast printing compared to high power systems
• Stable colors without sedimentation
• Compatible with standard investment casting workflows

This material is supplied as a professional manufacturing material and is not marketed as a finished product. Final casting performance, burnout behavior and process validation remain the responsibility of the user depending on printer, investment material and casting workflow.
