Methods of post-curing additive manufacturing parts using electron beams

A method of post-curing a plurality of 3D printed preformed parts comprising:

• 3D printing photopolymerizable resin to form a plurality of preformed parts, wherein a section of the preformed part post-cured with electron beams comprises a thickness of at least 1.0 centimeter;
• moving the plurality of preformed parts through an e-beam chamber comprising electron beams, wherein each of the plurality of preformed parts is irradiated with the electron beams and post-cured;
• and
• adjusting the energy of the electron beams and the duration of post-curing for each of the plurality of preform parts based on the thickness of the section, where the duration of post-curing is less than 60 seconds.

A method of post-curing a plurality of 3D printed preformed parts comprising:

• 3D printing photopolymerizable resin using UV curing to form a plurality of preformed parts, wherein a first subset of the plurality of preformed parts have a different shape than a second subset of the of the plurality of preformed parts and each of plurality of preformed parts each comprise at least one section with a dimension equal to or greater 1.0 centimeter;
• moving the plurality of preformed parts through an electron beam curing chamber comprising electron beams;
• and
• irradiating the first subset of preformed parts at a first electron beam dosage and the second subset of preformed parts at a second electron beam dosage with the electron beams as the plurality of preformed parts move through the electron beam curing chamber.
