SLA 3D prototyping is an additive manufacturing process based on layer-by-layer molding using photocurable resin.
It is primarily used for visual verification, detail demonstration, and assembly relationship checking, and is suitable for prototyping applications with specific requirements for dimensional accuracy and surface finish.
- High-precision photopolymerization molding capability: Capable of rendering detailed structures such as small holes, text, chamfers, and complex curved surfaces, used for prototyping fine parts.
- Multiple resin material compatibility: Can use ordinary resins, transparent resins, heat-resistant resins, or toughening resins to meet different design verification purposes.
- Rapid prototyping capability: Short molding process from 3D data to physical prototypes, supporting design review and version adjustments.
- Post-processing capabilities: Supports support removal and cleaning, secondary UV curing, local fine finishing, spray painting, and transparent polishing.
- Appearance near mass production state verification capability: Used to check product proportions, detail, and customer confirmation requirements.
- Minimum Order Quantity (MOQ): 1 piece minimum, suitable for single-piece samples and comparison of multiple appearance versions.
- Lead time range: Determined based on part size, complexity, and post-processing plan, typically several to over ten working days.
- Mass production transition notes: SLA prototypes are mainly used for appearance and structural verification and are not suitable for long-term use or mass production. Mass production requires switching to injection molding or other large-scale processes.
Q: Can SLA 3D prototypes be used as final products?
A: Generally, it's not recommended. SLA is better suited for appearance and structural verification, but not for long-term functional use.
A: SLA offers the best precision and surface quality, making it suitable for creating parts with intricate details; SLS and FDM focus more on functionality.
A: The original surface is very smooth, but support areas still require post-processing to achieve the best results.
