¶ 1. Material Information
¶ 1.1 Overview
Modeling PAS10 Black is a budget-friendly resin material featuring moderate strength and toughness, not easily to crack. Fast printing and production ability are excellent that it can print detailed, complex structures, while printed object is fast-curing, making post-processing fast and convenient. The matte finish performs well detailed surface and steadily. Low in viscosity and odor.
¶ 1.2 Recommendations on Applications
- Scenarios demanding in layer lines.
- Miniatures, mecha parts with many curved and flat parts.

¶ 3. Process and Configuration
¶ 3.1 Support Parameters
| Support parameters (regular resin tank) | ||
| Support areas | Parameter items | Default values |
| Support body | Lift height (mm) | 5 |
| Trunk diameter (mm) | 0.7 | |
| Overhang angle (°) | 40 | |
| Support density | Anchor distance (mm) | 2 |
| Border anchor distance (mm) | 2 | |
| Connection | Top diameter (mm) | 0.3 |
| Connection length (mm) | 1.5 | |
| Contact | Contact shape | Sphere |
| Diameter (mm) | 0.38 | |
| Embedded depth (mm) | 0.2 | |
Notes: For the first print, it's advised not to change the support parameters for successful printing. Sufficient supports are needed on areas such as lowest points and islands, considering the center of gravity shifting during printing, which might cause the object to shake and lead to misalignment. Appropriate improvements might be done on support parameters after the first print is successfully finished.
| Support parameters (printing with pulsing release resin tank) | |||
| Support areas | Parameter items | Default values | Minimum values |
| Support body | Lift height (mm) | 5 | 5 |
| Trunk diameter (mm) | 0.7 | 0.65 | |
| Overhang angle (°) | 40 | 35 | |
| Support density | Anchor distance (mm) | 2 | 2.5 |
| Border anchor distance (mm) | 2 | 2.5 | |
| Connection | Top diameter (mm) | 0.28 | 0.26 |
| Connection length (mm) | 1.5 | 1.5 | |
| Contact | Contact shape | Sphere | Sphere |
| Diameter (mm) | 0.38 | 0.36 | |
| Embedded depth (mm) | 0.2 | 0.2 | |
Notes: Using a Pulsing Release Resin Tank can hugely decrease the peeling force and improve the success rate of printing. Supports can be 30% less compared with those using a regular resin tank. But support parameter values are advised not to be weaker than the min. parameters provided above, or there will be some printing risks.

| Support areas | Parameter items | Default values |
| Basic config. | Z lift height (mm) | 5 |

| Raft thickness (mm) | 1.0 | |
| Overhang angle (°) | 45 | |
| Support density | Anchor distance (mm) | 2.0 |

| Voxeldance Tango (printing with regular resin tank) | ||
| Support areas | Parameter items | Default values |
| Basic config. | Z lift height (mm) | 5 |
| Raft shape | Convex hull | |
| Raft thickness (mm) | 1.0 | |
| Overhang angle (°) | 45 | |
| Support density | Anchor distance (mm) | 2.0 |

| Connection length (mm) | 15 | |
| Trunk Diameter (mm) | 0.9 | |
| Contact | Contact shape | Sphere |
| Diameter (mm) | 0.4 | |
| Embedded depth (mm) | 0.2 | |
Note: It's advised to use a "safer" parameter configurations and have some tests first, as HeyGears printers cannot guarantee a high printing success rate for models sliced with a third-party slicer software which does not enjoy HeyGears print strategies.
