Analysis of the Causes of 3D Printer Resin Cracking Problems
Resin 3d printing materials cracking is mainly divided into the following reasons:
1. The concentration of cleaning agent used in the cleaning process is not enough, and the residual 3D printer resin invades the surface of the printed part, making the surface of the printed part inconsistent with the internal stress, resulting in cracked surface cracking.https://www.esun3d.com/
2. The model has been hollowed out inside, there is a large amount of uncured resin 3d printing materials , and the interior is not completely cleaned with alcohol, or the wall thickness of the model after hollowing out is not enough (less than 3mm), and the thin-walled model will be damaged due to the uncured interior. The stress and the solidified thin wall produce molecular structure pulling, which leads to the overall collapse of the model.
3. Put the 3d printer resin model under a UV lamp of more than 30W for close-range one-way curing for a long time. Excessive secondary curing will cause uneven internal and external stress or inconsistent light reception before and after, resulting in interlayer cracking.
4. Do not blow dry the alcohol after cleaning, let the resin 3d printing materials model dry naturally and place it in the sun to receive light from one direction, forming deformation and cracking caused by strong pulling on the surface and internal stress.
5. Care should be taken when using water washable resin. https://www.esun3d.com/water-washable-resin-product/
Do not wash in water for a long time. After cleaning, dry it with a hair dryer as soon as possible. When storing the water washable resin model, avoid humid and high-temperature environments.

Aircraft Starter Generator DC 23080 Series 111 operates to help torque in engine starting and acts like a generator to provide DC electrical power once engine starting is completed. The starter’s generator’s output rating comes out to be 12kW, while the external power supply has a load of 2,000 Amps max at 28 VDC, .005 Ohms aircraft circuit resistance. Jet aircraft and flights of commercial and military establishments use the generators on turboprops which are machines with four main poles and interpolate. A fan towards the anti-drive end shaft is responsible for the forced air cooling. For more information visit our website.
