After seeing a question about FDM printing of temperature-resistant parts, high-temperature 2-part epoxy came to mind. Are there any (experimental or production) FDM extruders for laying viscous, fast-curing epoxy, mixing it at the last moment before extrusion? Or likewise other cured/resin materials, either 2-part or UV-cured (with whole print volume flooded with UV)?
Is this what you're looking for?
Material blasting is a unique 3D resin printing technology that can be compared to an office inkjet printer. It is also considered one of the fastest and most accurate 3D printing technologies available for resin printing today.
Material Beam 3D printers are similar to inkjet 3D printers in that they also have a print head from which thousands of tiny resin droplets are applied to the building platform and then cured with UV light. Once a layer has been completed, the building platform automatically lowers to the height of a layer and the process is repeated until the object is completed.
The technology of material blasting enables high dimensional accuracy, but speed is also a convincing point. The process in which the resin droplets are ejected from several print heads, which in turn move back and forth over the building platform, is known as line-by-line cutting. This ensures that multiple parts can be produced without affecting the build speed. As a user, you also have the choice between matte and shiny surfaces on your 3D printed object. However, the individual components for material beam technology are very cost-intensive. Other disadvantages are the waste of material when you choose to print matt surfaces and the low strength of the 3D printed parts.
Apparently now the answer is yes. A company called MASSIVit has a system they call GDP - gel dispensing printing - that's essentially what I asked about, on an extremely large scale. 3D Printing Nerd has a video from their booth at Formnext 2021 in Frankfurt, Germany.
