Additive Manufacturing & 3D Printing

Layer-by-layer fabrication of parts from polymers, resins, or metals, including vat photopolymerization (SLA), fused filament fabrication, and powder-bed fusion. Desktop and industrial machines now combine multi-material toolchanging, closed chambers, and in-process sensing. Vendors include Formlabs (resin SLA/SLS) and Bambu Lab (FFF with automatic hotend/printhead changing).

Key technical architectures and manufacturing innovations include:

• Cloud Manufacturing Execution & On-Demand DFM Platform: Cloud software platforms integrating automated 3D CAD manufacturability (DFM) analysis, instant dynamic pricing, digital inventory vaults, and intelligent routing across connected CNC, injection molding, and industrial 3D printing fleets.
• Fused Deposition Modeling (FDM): Material extrusion additive manufacturing process that dispenses heated thermoplastic filament through a moving nozzle along coordinated toolpaths to build three-dimensional parts layer by layer, invented by S. Scott Crump in 1988.
• Multi Jet Fusion (MJF): Powder bed additive manufacturing technology developed by HP utilizing thermal inkjet arrays to selectively deposit infrared fusing agents and detailing agents across thermoplastic powder beds (PA11, PA12, PP, TPU) followed by sweeping energy exposure to achieve high-speed isotropic plastic parts.
• Carbon Digital Light Synthesis (DLS / CLIP): Continuous liquid photopolymerization process utilizing oxygen-permeable windows to maintain a non-polymerized dead zone for continuous layerless printing, combined with secondary programmable thermal curing of dual-cure polyurethane and epoxy resins.
• High-Speed Laser-Assisted Desktop Material Extrusion: High-throughput desktop 3D printing system developed at the MIT Mechanosynthesis Lab combining a laser-assisted preheating mechanism with a screw-driven filament feed to increase extrusion rate and print speed by up to 10x over conventional desktop FDM.
• Selective Laser Sintering (SLS): Powder bed fusion additive process that uses high-power lasers to fuse powdered thermoplastics, ceramics, or metals layer by layer into dense solid structures without requiring temporary support geometries, invented by Carl Deckard and Joe Beaman.
