¶ Material Information
¶ Overview
Modeling PAT10 is a highly transparent material with a low price. It features excellent construction performance and the ability of fast printing. It can print complex and exquisite models with its stunning ability of appearance reproduction. Its print parts are easy to post-process (sanding and polishing, etc.) as it has a proper viscosity and little odor and is fast to be cured. Thanks to its proper toughness, its print parts do not easily crack even if falling from desktop.
¶ Recommendations on Applications
1. Transparent figure parts;
2. Prototyping validation of consumer electronics and so;
3. Transparent parts in end applications;
4. Transparent applications with demands in long-term anti-yellowing.

¶ Process and Configuration
¶ Support Parameters
| Support parameters (regular resin tank) | ||
| Support areas | Parameter items | Default values |
| Support body | Lift height (mm) | 5 |
| Trunk diameter (mm) | 0.9 | |
| Overhang angle (°) | 40 | |
| Support density | Anchor distance (mm) | 2.5 |
| Border anchor distance (mm) | 2 | |
| Connection | Top diameter (mm) | 0.36 |
| Connection length (mm) | 1.5 | |
| Contact | Contact shape | Sphere |
| Diameter (mm) | 0.5 | |
| Embedded depth (mm) | 0.25 | |
Note: As a tough material, Modeling PAT10 is relatively more difficult to print, and is sensitive to islands. For a success print, it's advised not to change the support parameters when printing with a regular resin tank for the first time. Sufficient supports are needed on areas such as lowest points and islands, considering the center of gravity shifting during the process of 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 (pulsing release resin tank) | |||
| Support areas | Parameter items | Default values | Min. values |
| Support body | Lift height (mm) | 5 | 5 |
| Trunk diameter (mm) | 0.7 | 0.6 | |
| 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 | 0.2 |
| Connection length (mm) | 1.5 | 1.5 | |
| Contact | Contact shape | Sphere | Sphere |
| Diameter (mm) | 0.35 | 0.25 | |
| Embedded depth (mm) | 0.20 | 0.15 | |
Note: Since the support parameters using regular resin tank are quite small already, when printing an object from the material, 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.
¶ Parameters for Slicing in Other Slicer Software (Not Recommended)
| Chitubox (printing with regular resin tank) | ||
| Support areas | Parameter items | Default values |
| Basic config. | Z lift height (mm) | 5 |
| Raft shape | Cross grid | |
| Raft thickness (mm) | 1.0 | |
| Overhang angle (°) | 45 | |
| Support Density | Anchor distance (mm) | 2.0 |
| Connection | Top diameter (mm) | 0.4 |
| Connection length (mm) | 1.5 | |
| Trunk diameter(mm） | 1.0 | |
| Contact | Contact Shape | Sphere |
| Diameter (mm) | 0.6 | |
| Embedded depth (mm) | 0.35 | |
| Voxeldance Tango (printing with regular resin tank) | ||
| Support areas | Parameter items | Default values |

| Trunk diameter(mm） | 1.0 | |
| Contact | Contact shape | Sphere |
| Diameter (mm) | 0.6 | |
| Embedded depth (mm) | 0.35 | |
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.
¶ Recommended Washing
| Material Cleaning Parameters | ||||
| Material | Cleaning devices | Washing settings | Cleaning solution | Washing time |
| UltraPrint-Modeling PAT10 | UltraCraft Wash | Rotation speed 180r/min | 95% alcohol | 3-min rough wash + 3-min fine wash |
| Ultrasonic cleaning | Power 240Kw | 95% alcohol | 3-min rough wash + 2-min fine wash | |
Note 1: Rough wash refers to the behavior of washing off most liquid resin on the printed object with used alcohol (used for more than 3 batches of prints); Fine wash refers to the behavior of well cleaning details of the printed object with clean alcohol (used for less than 3 batches of prints).
Note 2: Washing finished, it's advised to blow dry the print with compressed air or bake it dry in a baker at 40℃ for 10min. Please AVOID submerging the print in alcohol for a long time (over 10 min in total), which might impact the resin's performance and the print's dimension.
¶ Recommended Curing
| Material Curing Parameters | ||||
| Material | Curing modes | Heat or not | Curing media | Curing settings |
| UltraPrint-Modeling PAT10 | Rapid | No | Air | At room temperature for 7 min |
| Performance | Yes | Air | Pre-baking at 46 ℃ for 15 min + curing at 46℃ for 45min | |
Note 1: Cure the print with HeyGears UltraCraft Cure. It’s advised to send the curing job from HeyGears Blueprint to the device first and then start curing on the device, as the job sent from Blueprint would enjoy a more advanced curing process and have an even better curing result.
Note 2: It is common if the print part turns yellowish after curing. Leave the part for a week (cured in Rapid mode) or 1-2 days (cured in Performance mode), the color will fade.

¶ Sanding and Spray-Painting
The material requires sanding and spray-painting to achieve the desired transparency. You may refer to the steps below.
1.Grinding by hand
Use wet sandpaper (from 400 mesh to 1200 mesh) to grind off layer lines and support remains. It's advised to use sandpaper that is 200 mesh finer every time switching to finer sandpaper, and grind off scratches made by previous sandpaper. After grinding with 1200 mesh sandpaper, the surface of the print part will look fine and matte.
2.Washing
Wash off the dust from grinding with water first. Wipe off the dust and fingerprints until clean with microfiber cloth and IPA/95% alcohol.
3.Spraying
Dry the model prior to spraying, or the paint quality might be affected. The more the print part is sanded, the more transparent it turns. Spray the model in a dust-free environment.
-
It's suggested to use transparent acrylic spray primer. PAT10 goes well with most spray primers.
-
Another option is UV clear coat. UV clear coat needs to be cured with UV light. Some UV coat might turn 3D-printed objects more crispy, so it's advised to have some tests in advance.
