Chifukwa chiyani muyenera SLA mafakitale 3D chosindikizira.

Ndi osindikiza a 3D apakompyuta otsika mtengo, zida zosindikizira za 3D zosagwira kutentha, ndi makina omangira jakisoni, ndizotheka kupanga jekeseni wa 3D mnyumba kuti apange ma prototypes ogwira ntchito ndi magawo ang'onoang'ono, ogwira ntchito pamapulasitiki opanga. Pakupanga kocheperako (pafupifupi magawo 10-1000), ma jekeseni osindikizidwa a 3D amapulumutsa nthawi ndi ndalama poyerekeza ndi nkhungu zachitsulo zodula. Amathandiziranso njira yopangira zinthu zakale kwambiri, zomwe zimalola mainjiniya ndi opanga kupanga mawonekedwe a jekeseni ndikuyesa masinthidwe a nkhungu kapena kusintha mosavuta nkhungu ndikupitiliza kubwereza mapangidwe awo ndi nthawi yotsika komanso mtengo wake.

Ukadaulo wosindikizira wa SLA 3D ndi chisankho chabwino pakuumba. Amadziwika ndi kutsetsereka kosalala komanso kulondola kwambiri kuti nkhungu idzasamutsira ku gawo lomaliza komanso kumathandizira kugwetsa. Zosindikiza za 3D zopangidwa ndi SLA zimamangirizidwa ndi mankhwala kotero kuti zimakhala zowirira kwambiri komanso za isotropic, zomwe zimapanga zisankho zogwira ntchito pamtundu womwe sungatheke ndi fused deposition modelling (FDM). Makina osindikizira a Desktop ndi benchtop SLA, monga omwe amaperekedwa ndi Ma Formlabs, amathandizira kayendedwe kantchito chifukwa ndi osavuta kugwiritsa ntchito, kugwiritsa ntchito, ndi kukonza.

Formlabs Rigid 10K Resin ndi zinthu zamafakitale, zodzazidwa ndi magalasi kwambiri zomwe zimagwira ntchito ngati chinthu choyenera kuumba pamitundu yosiyanasiyana ya ma geometries ndi njira zopangira jakisoni. Resin 10K Resin ili ndi HDT ya 218 ° C @ 0.45 MPa ndi 10,000 MPa modulus, yomwe imapangitsa kuti ikhale yolimba, yolimba kwambiri, komanso yosasunthika yomwe imapangidwira kuti ikhale ndi mawonekedwe ake pansi pa kupanikizika ndi kutentha kuti ipange mbali zolondola.

Rigid 10K Resin ndizomwe zimapangidwira kusindikiza nkhungu zapamwamba zopangira jakisoni, zomwe timawonetsa ndi maphunziro amilandu atatu pamapepala athu oyera. Chipatala chaukadaulo chaku France IPC idachita kafukufuku ndikusindikiza magawo masauzande ambiri, opanga makontrakitala Multiplus amawagwiritsa ntchito popanga zida zochepa, ndipo kampani yopanga zinthu ya Novus Applications yabaya mazana a zipewa zokulungidwa movutikira ndi nkhungu imodzi Yokhazikika ya 10K Resin.

High Temp Resin ndi chinthu china chomwe chitha kuganiziridwa ngati kukakamiza ndi jekeseni sikukwera kwambiri ndipo Rigid 10K Resin sungakwaniritse kutentha kofunikira. High Temp Resin ili ndi kutentha kwa kutentha (HDT) kwa 238 ° C @ 0.45 MPa, yapamwamba kwambiri pakati pa ma resin a Formlabs komanso imodzi mwapamwamba kwambiri pakati pa ma resins pamsika, kuwalola kupirira kutentha kwapamwamba ndikuchepetsa nthawi yozizira. Pepala lathu loyera limadutsamo kafukufuku ndi Braskem, kampani ya petrochemical yomwe idayendetsa ma jakisoni 1,500 ndi choyika chimodzi cha nkhungu chosindikizidwa ndi High Temp Resin kuti apange zingwe zomangira. Kampaniyo idasindikiza choyikacho ndikuchiyika mkati mwa nkhungu yachitsulo chosakanizidwa ndi jakisoni. Iyi ndi njira yamphamvu yopangira mndandanda wapakatikati mwachangu.

High Temp Resin, komabe, ndizovuta kwambiri. Pankhani ya mawonekedwe ovuta kwambiri, amapindika kapena kusweka mosavuta. Kwa mitundu ina, kufikira mizere yopitilira khumi ndi iwiri kungakhale kovuta. Kuti athane ndi vutoli, Ili ndi kutsika kwamafuta otsika kuposa High Temp Resin, yomwe imatsogolera ku nthawi yayitali yozizirira, koma imakhala yofewa ndipo imatha kupirira ma cycle mazana.
