Abstract
The present disclosure is directed towards resin compositions and methods of making and using the same, where the resulting resins (e.g. SLA resins) can be utilized in conjunction with additive manufacturing.
Claims22
A composition, comprising:
- an epoxy component;
- a reactive diluent component;
- a macro dendritic component;
- and
- a photo initiator component;
- configured in an amount to catalyze the epoxy, the reactive diluent, and the macro dendritic component into a resin configured for additive manufacturing an AM component via vat polymerization.
A composition, consisting essentially of:
- an epoxy component;
- a reactive diluent component including a oxetane;
- a macro dendritic component having a hyperbranched polyester;
- and
- a UV curable photo initiator component;
- configured in an amount to catalyze the epoxy, the reactive diluent, and the macro dendritic component into an KA resin configured for additively manufacturing an AM green form component via stereolithography.
A composition, consisting of:
- at least 65 wt. % to not greater than 85 wt. % an epoxy component;
- at least 10 wt. % to not greater than 20 wt. % of a dendritic macromolecule component;
- and
- at least 0.05 wt. % to not greater than 15 wt. % of a photo initiator component.
A composition, consisting of:
- at least 50 wt. % to not greater than 85 wt. % of an epoxy component;
- at least 5 wt. % to not greater than 20 wt. % of a dendritic macromolecule component comprising a hyperbranched polyester;
- not greater than 15. wt. % of a reactive diluent component, wherein at least some reactive diluent component is present;
- and
- at least 0.05 wt. % to not greater than 15 wt. % of a photo initiator component.
A method, comprising:
- componentcomponent componentcomponentdepositing, positioning, spreading, extruding, spraying, rolling, dipping, wiping, casting, and/or combinations thereof, to form a layer of SLA resin on a surface (e.g. substrate or previous AM build surface).
- componentcomponent componentcomponent,
- the plurality of AM green form parts including at least a first AM green form part and a second AM green form part;
The method of claim 23, wherein the vat polymerization process further comprises stereolithography.
The method of claim 23, wherein the AM part comprises a polymeric preform for investment casting.
The method of claim 23, wherein the AM part comprises a structural component.
The method of claim 23, wherein the AM part comprises a functional component.
