Abstract
Izum pod nazivom 'Uređaj za beskontaktnu paralelnu fotopolimerizaciju u tehnologiji 3D printanja odozgo prema dolje' se odnosi na način pripreme UV svjetlosnog snopa (2) koji se koristi za polimerizaciju foto osjetljive smole (7) kod SLA 3D printera u 'Top down' principu rada.Izum se sastoji od uređaja koji obuhvaća izvor svjetla (1), optičkog sustava za paralelizaciju svjetlosnog snopa (3) te digitalne maske (9) (monokromatski LCD) kroz koju se projicira željeni oblik na površinu fotopolimerne smole (8).Uređaj paralelizira svjetlo (2) kojim se osvjetljava površina fotopolimera (8) gdje se odvija polimerizacija. Primjenom ovog izuma omogućava se veća brzina izgradnje 3D modela, postiže se veća preciznost te u konačnici utječe na pojeftinjenje izrade 3D modela. Također, ovim uređajem je moguće printati 3D modele velikih dimenzija. Inovativnost izuma je u tome što omogućava LCD SLA 3D printerima da rade u 'Top down' načinu rada a da pri tom ne dolazi do nikakvog mehaničkog stresa.The invention entitled 'Device for non-contact parallel photopolymerization in top down 3D printing technology' refers to the method of preparing the UV light beam (2) used for the polymerization of photo-sensitive resin (7) in SLA 3D printers in the 'Top down' operating principle.The invention comprises a device that includes a light source (1), an optical system for parallelizing the light beam (3) and a digital mask (9) (monochromatic LCD) through which the desired shape is projected onto the surface of the photopolymer resin (8).The device parallelizes the light (2) which illuminates the surface of the photopolymer (8) where the polymerization takes place. The application of this invention enables a higher speed of building 3D models, achieves greater precision and ultimately affects the cost of making 3D models. Also, with this device, it is possible to print 3D models of large dimensions.The innovation of the invention is that it enables LCD SLA 3D printers to work in 'Top down' mode without causing any mechanical stress.
