Abstract
Provided herein are methods for making 3D printed parts by additive manufacturing using post processing cleaners.
Claims32
A composition comprising:
- (a) One or more alkylene glycols;
- (b) One or more alkylene glycol ethers;
- (c) One or more alkoxylated aromatic alcohols;
- and
- (d) An antioxidant component;
- and
- a photo-initiator component selected from an α-hydroxyketone, a phenylglyoxylate, a benzyl dimethyl ketal, a mono acyl phosphine oxide, a bis acyl phosphine oxide, and mixtures thereof.
4 more elements
A composition comprising:
- (a) One or more alkylene glycols;
- (b) One or more alkylene glycol ethers;
- (c) One or more alkoxylated aromatic alcohols;
- and
- (d) An antioxidant component
- wherein the alkylene glycol ether(s) (b) is(are) present in an amount of about 50 to about 75 percent by weight.
3 more elements
A method of washing a 3D printed part made by additive manufacturing, comprising the steps of:
- (a) Contacting with a composition comprising:
- (i) A combination of alkylene glycol ethers comprising dipropylene glycol methyl ether and tripropylene glycol methyl ether;
- (ii) One or more alkoxylated aromatic alcohols comprising benzyl alcohol ethoxylate;
- and
- (iii) An antioxidant component comprising propyl gallate,
- an additive manufacturing-made 3D printed part, said 3D printed part made from a photocurable resin composition, and having at least one surface;
- and
- (b) Contacting said 3D printed part with a non-aqueous rinse liquid;
- and
- (c) Removing said 3D printed part in step (b) from contact with said composition, and optionally, contacting said 3D printed part with water and/or air for a time sufficient to remove substantially all of any composition and/or water, respectively, remaining on said 3D printed part.
