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.

Juice, sauce, little bit of dressing
Ice, wrist, little bit of flexing
Juice, sauce, little bit of dressing
Ice, wrist, little bit of flexing
I went to the store for some chocolate flavoured milk
Came home with a thicc chocolate colored milf
All she wanted was a little gravy train for Christmas
She was pretty interested in giving me the business
Pretty sure I was like twenty when it happened (flex)
Speakers playing Marvin Gaye, so I started snapping
All of a sudden Momma had her ass clapping
We where in the aisle with the paper and the napkins
I was mesmerised by the was that it was shakin'
Looked down at her cart and all she had was bacon
Ooh shit, I think she want some breakfast
But out the corner of my eye I saw my fuckin' dentist
Juice, sauce, little bit of dressing
Ice, wrist, little bit of flexing
Juice, sauce, little bit of dressing

Came home with a thicc chocolate colored milf
All she wanted was a little gravy train for Christmas
She was pretty interested in giving me the business
Guess it turned out that my dentist was a wife
Same dentist I had already piped thrice
I'm not trying to pull up on your wife girl I promise
But it's starting to look a lot like Trapped in the Closet
I was thinking about that masterpiece by R-Kelly
When suddenly my dentist started rubbing on my belly
Looked down at her cart, she had the biscuits with the jelly
That's the time that Gravy hit a threesome in the deli
Gravy got racks, and my baby got back
Serenading your bitch on the sax
No slack in my mac, you better relax
That my crib, scented candles with the dirty sprite
R-Kelly playing while I lay that pipe
Fuckin' with your bitch all night
I pull up with that pipe, I'ma
Pull up on your bitch, pull up with that bitch I'ma
