Warping

[PhilH]

As the title suggest every now and then I get warping in my resin prints. Although I can post print mainly straighten it using a heat gun I was wondering if there's a magic cure to stop it, or is it simply an unwanted product of the process of 3-D resin printing.

 

I exclusively use ABS like resin as in most cases I quite like the slight flexibility it gives, but is this a double edge sword inasmuch it can contribute to the warping?

Resin shrinks as it cures, so keep a uniform wall thickness throughout as a minimum, and add ribbing in large flat areas. Uneven thicknesses shrink at different rates - hence warp.

Resins absorb the IPA and water used for cleaning. The prints need to be well-dried before curing. I leave mine at least 24 hours before removing the supports and curing.

I run a mix of standard and ABSlike about 50 50 or so

100% ABSLike for small details.

Longer exposures

 

Seems to be more stable

I use Anycubic water washable resin.

 

Print, thoroughly wash, drain off, dry (airbrush with nothing in), cure and then remove supports. I have not noticed any warp-age.

Curing with the supports in place will help that, but not something I'm a fan of due to the risk of breaking bits off when removing supports.

Thanks for the replies. I did as suggested in the first reply and basically left a print which included fairly long flat pieces overnight to dry (I too have an old airbrush and compressor which I use to start the drying process) then cured it. At the moment it seems to be as flat as a pancake so we shall see.
