3. Work Flow
- Printing
Blu-tough resin is a versatile material that can be used with different types of 3D
printers. It is specially designed for MSLA/LCD printers yet, it can also be printed on some of the 405nm SLA and DLP printers if you have access to exposure control.
To achieve optimal results with Blu tough resin, you need to use the appropriate slicer profiles for your printer model and software. You can download the slicer profiles for Chitubox and Lychee slicers from this link: Profiles for Different Printers
Please download the test model and view the tutorial: V5 Test model. This model provides more accurate exposure results than many commonly used test models like XP2 and REFE.
- Clean
Here are some tips for cleaning your printed parts:
- Use a painter brush (or any brush made with hair) to remove excess resins on the printed part.
- Use 95% concentrated Ethanol (preferred) or IPA to clean. Some form of methanol should work but make sure it does not contain acetone.
- Do not submerge the parts in alcohol for more than 5 minutes.
- After cleaning, remove alcohol as soon as possible with a hair dryer or air blower.
- For complex parts with lots of cavities, it may be a good idea to clean/dry multiple times.
You can check by touching the dried surface of the part to see if it is still sticky. If
the dried surface is still sticky, wash some more and dry again.
- Post Curing
Here are some tips for post-curing your printed parts:
- Blu reached its optimal strength when the printed part was post-cured with UV light after cleaning. Use 395-405nm UV light and cure for about 15 minutes.
- Make sure the resin is completely cleaned off, and there is no alcohol left (it needs to be dry) on the print before curing.
- Curing by submerging the object in water will significantly increase curing efficiency.
