Cleaning Step / Category |
Instructions & Recommendations |
|
Cleaning Solvents |
β’Β Preferred: 95% concentrated Ethanol or IPA. β’ Alternative: Methanol (must not contain acetone). |
|
Cleaning Time |
Submerge parts in the solvents for 4-5 minutes, using the ultrasonic cleaner. |
|
Submersion Limit |
DoΒ notΒ submerge parts in alcohol for more thanΒ 5 minutes. |
|
Extra Step |
For complex models, use a painter brush (or any brush made with hair) to gently remove excess resin from the printed part. |
Drying
|
Drying |
Remove alcohol by using an oven for 7-8 minutes (using a hair dryer requires 10 minutes) |
|
Note: For complex parts with cavities, repeat the clean/dry cycle multiple times. |
|
|
Quality Check |
Touch the dried surface. If it is still sticky, wash and dry the part again until smooth. |
Post Curing
|
Step / Factor |
Instructions & Recommendations |
|
Pre-curing Checklist |
Ensure the part is completely clean of excess resin andΒ fully dryΒ (no alcohol left) before starting. |
|
UV Specifications |
Use a UV light source with a wavelength ofΒ 395-405nm. |
|
Curing Time |
Cure for approximatelyΒ 15 minutesΒ to achieve optimal strength. |
|
Efficiency Tip |
Submerge the printed object in water during the UV curing process to significantly increase curing efficiency. |
