User Guide for Sculpt

7
Sculpt is developed to be as the go-to resin for model makers with high hardness, great surface finish, excellent resolution and high temperature resistance at 160C
8
Not only prints made with Sculpt is easy to get great looks with minimal post-processing effort. The hitemp feature allows Sculpt be used to make vulcanized rubber molds or to be printed as mold.
9
10
Due to higher polymer content for its outstanding mechanical properties, the ideal printing condition for Sculpt is over 25C.
11
If user can maintain a resin temperature of 30C, the printing time could be further reduced
12
It is recommended to shake Sculpt bottle vigorously before pouring

* Important, before printing Sculpt
15
Sculpt has that dark grey colors that model makers love, and we have already seen some great prints. However, it is also the only Siraya Tech resin that has pigments, and it may settle. To get the best results out of Sculpt, SHAKE HARD (applies to all resins with pigments)

To do it correctly to shake that bottle for 20-30s before use. Stir up the resins that is already in the vat before each print. And if you just received Sculpt, before opening it up for the first time, turn it upside down for a minute (submerged in warm water is even better) and then shake for another minute or two to make sure you get a great mix.

IF you want to take it to next level, throw a small metal ball in there and shake, the object will significantly increase the efficiency of mixing pigments and resins.

- 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.

Before Printing
33
It is a good practice to mix resin and expose the bottom of the vat to air before printing. This replenish oxygen in the vat and helps reduce peel force.
34
Sculpt especially benefit from mixing because it has pigments and may settle over time
35
It would also ensure print consistency if user can get the initial resin temperature above 25 and keep the environmental temperature above 20 C
36
37
Cleaning:
38
Use a painter brush (or any brush made with hair) remove excess resins on the printed part with Use 95% concentrated Ethanol or IPA to clean.
39
Do not submerge the parts in alcohol for more than 30 seconds. After 2-3 minutes of cleaning action, remove alcohol with a hair dryer or air blower. For complex part with lots cavities, it may be a good idea to clean/dry multiple times.
40
User can check by touching the dryed surface of the part to see if it is still sticky. If the dryed surface is still sticky, wash some more and dry again.
41
42
Sanding is easy with Sculpt. Use 1000 grit sand paper with a bit of mineral oil or water. Mineral oil adds lusters
43
44
Post Curing:
45
Sculpt reached its optimal strength when the printed part is post-cured with UV after cleaned. Use 395-405nm UV light and cure for about 15 minutes.
46
Make sure resin is completely cleaned off and there is not alcohol left (it needs to be dry) on the print before curing.
47
Curing by submerging object in water will significantly increase curing efficiency
