Blu User Guide

Blu is developed to be a strong resin that has a high resolution, precision, and is easy to print. It is tough and hard enough for making functional parts yet easy to print and clean for general use.

And it should not stink up the user's work environment.

Due to the higher polymer content for its outstanding mechanical properties, the ideal printing condition for Blu is over 25C.
If user can maintain a resin temperature of 30C, the printing time could be further reduced.

Slash Siraya on the Slash is better than anything I’ve tried...and I’ve tried 5-6 other resins on the Slash. Example from left to right are 100um, 75um, and 50um. The one I’m holding is 50um.

100um 5 sec
75um 4 sec
50um 3.5 sec
25um 2.8 sec
10um 2.5 sec

- LED power 250 (default)
- First layer for all 12sec/ first 3 layers (default amount).
- Slow setting for Lift speed
- 8mm lift height is safest and allow time resin to flow back (they only allow you to pick from 3,8, and 15mm height...which sucks...I'd like 6mm if I could.
- Cooldown between layers on auto (smaller prints i do 2sec to speed things up)
- Supports point(head) size no less than 1mm, but 1.5 is recommended with 2mm shaft.

It is best to use island style base like below left, not the raft style on the right. If you have a problem keeping the first layer on, make sure you level again to minimize gap between build plate and LCD screen

Cleaning:
Use a painter brush (or any brush made with hair) remove excess resins on the printed part with Use 95% concentrated Ethanol (preferred) or IPA to clean. Some form of methnol 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 part with lots cavities, it may be a good idea to clean/dry multiple times.
Users 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:
Blu reached its optimal strength when the printed part is post-cured with UV 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 objects in water will significantly increase curing efficiency
