Brief description: SLA resins are intended for 3D printing using stereolithography. In this process, liquid resin is cured layer by layer by UV light to create detailed and smooth objects. SLA resins are ideal for fine details and complex geometries, but are less robust compared to thermoplastic filaments.
Suitable uses:
- Detailed models and prototypes
- Jewelry and art objects
- Dental applications
- Molds for casting applications
Unsuitable uses:
- Mechanically stressed components
- Objects that are exposed to permanent sunlight or high temperatures
- Objects that require flexibility or high impact resistance
Technical data: (The exact values may vary depending on the specific resin type)
| Feature | Value (typical range) |
|---|---|
| Density | 1.05-1.20 g/cm³ |
| Tensile strength | 35-70 MPa |
| Elongation at break | 1-15 % |
| Heat deflection temperature | 40-100 °C |
| Shore hardness | 80-90 D (depending on the resin) |
| Bending modulus | 1.5-3.0 GPa |
| Bending strength | 50-100 MPa |
| Impact resistance | Varies greatly depending on the resin |
As SLA resins come in a wide variety, the specific properties depend heavily on the type of resin selected. It is advisable to consult the technical data sheets of the respective manufacturer to obtain precise information.
