Systems and methods resolve stresses in additive manufacturing. A stress resolution profile including frequency and amplitude parameters of an ultrasonic input are determined based on physical properties of the product. Successive layers of a material are added and energy is applied to incorporate the material of each layer into the product. An ultrasonic input is applied with the determined parameters to resolve stress as the product is built up. The ultrasonic input is varied as a depth of the material incorporated into the product increases.

Tunable system and method for stress resolution in additive manufacturing

Prior to manufacturing a product by additive manufacturing, a stress relief profile including frequency and amplitude parameters of an ultrasonic input is determined based on physical properties of the product, including resonant frequencies of the product and a material from which the product is manufactured. Successive layers of a material are added and energy is applied to incorporate the material of each layer into the product. A processor accesses stress relief profile parameters for each layer, determines whether a layer requires stress relief and determines a frequency and a power level for the stress relief at the layer. An ultrasonic input is applied with the determined parameters to relieve stress as the product is built up.

A method for determining and optimizing manufacturing of an object by additive manufacturing. One or more computers access a three-dimensional digital model of the object and automatically generate a selected number of versions of supports for manufacture of the object. An image of the generated supports is displayed along with the object for visual perception by a user. The user visually observes the displayed versions of supports and object and uses the images to evaluate whether manufacturing the object by additive manufacturing is viable and whether the additive manufacturing supports are optimized. When viable, the object may be built by additive manufacturing using the optimized additive manufacturing supports to support the object.
