METHOD AND SYSTEM OF FLOW BED ASSISTED PHOTOPOLYMERIZATION BASED ADDITIVE MANUFACTURING (F-PAM) - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240217172 titled 'METHOD AND SYSTEM OF FLOW BED ASSISTED PHOTOPOLYMERIZATION BASED ADDITIVE MANUFACTURING (F-PAM)

The abstract describes a method of additive manufacturing that involves forming a flow bed with a carrier fluid and/or fillers, depositing a precursor matrix fluid to create an interface layer, delivering a light beam to cure the interface layer in the shape of the current layer of the item being added, moving the current layer, and repeating the process for each successive layer of the item.

  • Forming a flow bed with a carrier fluid and/or fillers
  • Depositing a precursor matrix fluid to create an interface layer
  • Curing the interface layer with a light beam in the shape of the current layer of the item being added
  • Moving the current layer above or below the interface layer
  • Repeating the process for each successive layer of the item

Potential Applications: - 3D printing - Prototyping - Custom manufacturing

Problems Solved: - Efficient additive manufacturing process - Precise layer-by-layer construction - Ability to use a variety of materials

Benefits: - Faster production times - Reduced material waste - Enhanced design flexibility

Commercial Applications: - Manufacturing industries - Aerospace - Medical device production

Questions about the technology: 1. How does this method compare to traditional additive manufacturing techniques? 2. What types of materials can be used in this process?

Frequently Updated Research: - Ongoing studies on optimizing the curing process for different materials and structures.


Original Abstract Submitted

a method of additive manufacturing for creating an item, comprising (a) forming a flow bed (fb) comprising a flowing stream or layer of a carrier fluid and/or fillers; (b) depositing a layer of a precursor matrix fluid on top of the fb or below the fb to create an interface layer comprising a mixture of the precursor matrix fluid and fillers; (c) delivering a light beam patterned to a current layer of the item being added through the fb and into the interface layer to cure a portion of the interface layer in a shape of the current layer of the item being added; (d) moving the current layer of the item above or below the interface layer; and (e) repeating (c) and (d) for each successive layer of the item.
