The status quo they describe is a printing process where material is deposited and then UV cured, then there’s some kind of scraping process. That seems like a hybrid of FDM and lithographic printing from a vat of goo a la FormLabs.
Industrial equipment uses this technique often for different purposes like glueing. Might seem obvious but the scraping is an artifact from the UV curing, it happens for SLA printers too. There’s a reason why the vat is a FEP film since it has lubricating properties like PTFE so each layer peels off easily. Also fun fact, that’s what carbon3D printers are so damn fast. They have a semi permeable film that lets oxygen through which creates a thin barrier of “cured yet viscous” resin between the film and part so they don’t have to wait to peel or scrape anything.
Is that a common process?
