Utomoni wowonjezera wosindikizidwa wa 3D

Gawo loyamba la kafukufukuyu linayang'ana kwambiri kusankha monomer yomwe ingakhale ngati chomangira cha utomoni wa polymer. Monomeryo iyenera kukhala yokhoza kuchiritsidwa ndi UV, yokhala ndi nthawi yochepa yochira, komanso kuwonetsa mphamvu zabwino zamakina zoyenera kugwiritsidwa ntchito pamavuto akulu. Gululo, litayesa anthu atatu omwe angakhalepo, pamapeto pake linasankha kugwiritsa ntchito 2-hydroxyethyl methacrylate (tingoitcha HEMA).

Monomer itatsekedwa, ofufuzawo adayamba kupeza kuchuluka kwabwino kwa photoinitiator pamodzi ndi chopangira chopukutira choyenera kuti chigwirizane ndi HEMA. Mitundu iwiri ya photoinitiator idayesedwa kuti ione ngati ikufuna kuchiritsa pogwiritsa ntchito magetsi a UV a 405nm omwe amapezeka kwambiri m'machitidwe ambiri a SLA. Photoinitiators adaphatikizidwa mu chiŵerengero cha 1:1 ndikusakanikirana ndi 5% polemera kuti apeze zotsatira zabwino kwambiri. Chopangira chopukutira - chomwe chingagwiritsidwe ntchito kuthandizira kukulitsa kapangidwe ka maselo a HEMA, zomwe zidapangitsa kuti 'thovu' - chinali chovuta kupeza. Zambiri mwa zoyesererazo sizinasungunuke kapena zinali zovuta kuzikhazikitsa, koma gululo pamapeto pake lidasankha chopangira chopukutira chomwe sichinali chachikhalidwe chomwe chimagwiritsidwa ntchito ndi ma polima ofanana ndi polystyrene.

Kusakaniza kovuta kwa zosakaniza kunagwiritsidwa ntchito popanga utomoni womaliza wa photopolymer ndipo gululo linayamba kugwira ntchito yosindikiza 3D mapangidwe angapo a CAD omwe sanali ovuta kwenikweni. Mitunduyo inasindikizidwa 3D pa Anycubic Photon pa sikelo ya 1x ndipo inatenthedwa pa 200°C kwa mphindi khumi. Kutentha kunawononga chinthu chopukutira, kuyambitsa ntchito ya thovu la utomoni ndikukulitsa kukula kwa mitunduyo. Poyerekeza miyeso isanayambe ndi itatha kukula, ofufuzawo anawerengera kuchuluka kwa volumetric mpaka 4000% (40x), kupititsa patsogolo mitundu yosindikizidwa ya 3D kudutsa malire a mbale yomangira ya Photon. Ofufuzawo amakhulupirira kuti ukadaulo uwu ungagwiritsidwe ntchito pazinthu zopepuka monga aerofoils kapena zothandizira kuyenda chifukwa cha kuchuluka kochepa kwambiri kwa zinthu zotambasulidwa.
