Chikamu chekutanga chechidzidzo chaive chakanangana nekusarudza monomer yaizoshanda sechivakwa chepolymer resin. Iyo monomer yaifanirwa kuve inorapika-UV, kuve nenguva ipfupi yekurapa, uye kuratidza inodiwa michina zvivakwa zvakakodzerwa nepamusoro-kushushikana kunyorera. Chikwata ichi, mushure mekuyedza vatatu vangangokwikwidza, vakazogara pa2-hydroxyethyl methacrylate (tichangoidaidza kuti HEMA).
Kana iyo monomer ichinge yavharirwa mukati, vaongorori vakatanga kutsvaga iyo yakanyanya kunaka photoinitiator kusungwa pamwe chete neakakodzera inofuridza mumiriri wekubatanidza iyo HEMA nayo. Mhando mbiri dzefotoinitiator dzakaedzwa kuti dzide kurapa pasi peyakajairwa 405nm UV marambi anowanzo kuwanikwa mune mazhinji maSLA masisitimu. Iwo mafotoinitiators akasanganiswa muchiyero che1: 1 uye akasanganiswa mu5% nehuremu kune yakanyanya kunaka mhedzisiro. Iyo inofuridza - iyo yaizoshandiswa kufambisa kuwedzera kweiyo HEMA's cellular chimiro, zvichikonzera 'kupupa' - raive diki diki kuwana. Mazhinji emaajenti akaedzwa akange asinganyungudike kana kunetsa kudzikamisa, asi timu yakazogara pane isiri yechinyakare inofuridza iyo inowanzo shandiswa nepolystyrene-senge mapolymer.
Musanganiswa wakaomarara wezvishandiso wakashandiswa kugadzira yekupedzisira photopolymer resin uye timu yakatanga kushanda pa 3D kudhinda mashoma asiri-akanyanya kuoma eCAD magadzirirwo. Mamodheru acho aive 3D akadhindwa paAnycubic Photon pachikero che1x uye akadziya pa200°C kwemaminetsi anosvika gumi. Iko kupisa kwakaodza iyo inofuridza, ichimisikidza iyo inopupuma chiito che resin uye kuwedzera saizi yemhando. Pakuenzanisa pre- ne-post-expansion dimensions, vaongorori vakaverenga mavhoriyamu ekuwedzera anosvika 4000% (40x), vachisundidzira mamodheru akadhindwa e3D kupfuura kuganhurirwa kwedimensional yeFotoni's kuvaka ndiro. Vatsvagiri vanotenda kuti tekinoroji iyi inogona kushandiswa kuita zvinyoro-nyoro senge aerofoils kana buoyancy aids nekuda kwekudzikira kwakadzikira kwezvinhu zvakawedzerwa.
