Hano hari ibihumbi byinshi bya plastiki kumasoko kugirango yihute prototyping cyangwa umusaruro muto - guhitamo plastike ibereye kumushinga runaka birashobora kuba byinshi, cyane cyane kubashaka guhanga cyangwa abashaka kwihangira imirimo. Buri bikoresho byerekana ubwumvikane mubijyanye nigiciro, imbaraga, guhinduka no kurangiza hejuru. Birakenewe gusuzuma gusa ikoreshwa ryigice cyangwa ibicuruzwa, ariko nanone nibidukikije bizakoreshwa.
Muri rusange, plastiki yubuhanga yazamuye imiterere yubukanishi itanga igihe kirekire kandi idahinduka mugihe cyo gukora. Ubwoko bumwebumwe bwa plastiki burashobora kandi guhindurwa kugirango butezimbere imbaraga, hamwe ningaruka no kurwanya ubushyuhe. Reka twibire mubikoresho bitandukanye bya pulasitike kugirango dusuzume ukurikije imikorere yigice cyanyuma cyangwa ibicuruzwa.
Imwe mumyanda ikunze gukoreshwa mugukora ibice byubukanishi ni nylon, izwi kandi nka polyamide (PA). Iyo polyamide ivanze na molybdenum, iba ifite ubuso bworoshye bwo kugenda byoroshye. Nyamara, ibikoresho bya nylon-kuri-nylon ntibisabwa kuko, nka plastiki, bikunda gufatana. PA ifite imyambarire myinshi no kurwanya abrasion, hamwe nibikoresho byiza bya mehaniki mubushyuhe bwinshi. Nylon nigikoresho cyiza cyo gucapa 3D hamwe na plastiki, ariko ikurura amazi mugihe.
Polyoxymethylene (POM) nayo ni amahitamo meza kubice bya mashini. POM ni resin ya acetal ikoreshwa mugukora Delrin ya DuPont, plastike yagaciro ikoreshwa mubikoresho, imigozi, ibiziga nibindi. POM ifite imbaraga zihindagurika kandi zikomeye, gukomera no gukomera. Nyamara, POM yangijwe na alkali, chlorine namazi ashyushye, kandi biragoye gukomera hamwe.
Niba umushinga wawe ari ubwoko bwa kontineri, polypropilene (PP) niyo ihitamo ryiza. Polypropilene ikoreshwa mububiko bwibiryo kuko irwanya ubushyuhe, itabuza amavuta nuwashonga, kandi ntisohora imiti, bigatuma irya neza. Polypropilene ifite kandi uburinganire buhebuje bwo gukomera no gukomera, bigatuma byoroha gukora imirongo ishobora kugororwa inshuro nyinshi itavunitse. Irashobora kandi gukoreshwa mu miyoboro no mu mazu.
Ubundi buryo ni polyethylene (PE). PE ni plastiki ikunze kugaragara kwisi ifite imbaraga nke, gukomera no gukomera. Ubusanzwe ni amata yera yuzuye amata akoreshwa mugukora amacupa yimiti, amata nibikoresho byogeramo. Polyethylene irwanya cyane imiti myinshi ariko ifite aho ishonga.
Ibikoresho bya Acrylonitrile butadiene styrene (ABS) nibyiza kumushinga uwo ariwo wose usaba kurwanya ingaruka zikomeye no kurira cyane no kuvunika. ABS yoroheje kandi irashobora gushimangirwa na fiberglass. Birahenze kuruta styrene, ariko bimara igihe kinini kubera ubukana n'imbaraga. Fusion-molded ABS 3D moderi ya prototyping yihuse.
Urebye imiterere yacyo, ABS ni amahitamo meza yo kwambara. Kuri Star Rapid, twashizeho isaha yubwenge ya E3design dukoresheje inshinge zabitswe umukara wabanje gushushanya irangi rya plastike ABS / PC. Ihitamo ryibikoresho rituma igikoresho cyose cyoroha, mugihe kandi gitanga urubanza rushobora kwihanganira ihungabana rimwe na rimwe, nkigihe isaha ikubise hejuru. Ingaruka nyinshi polystirene (HIPS) nuguhitamo kwiza niba ukeneye ibintu byinshi kandi birwanya ingaruka. Ibi bikoresho birakwiriye gukora ibikoresho biramba byigihe kirekire nibikoresho byimikorere. Nubwo HIPS ihendutse, ntabwo ifatwa nkibidukikije.
Imishinga myinshi isaba inshinge zo guterwa inshinge hamwe na elastique nka rubber. Thermoplastique polyurethane (TPU) nuguhitamo kwiza kuko ifite formulaire nyinshi zidasanzwe zo gukomera, gukora ubushyuhe buke no kuramba. TPU ikoreshwa kandi mubikoresho byamashanyarazi, kuzunguruka, kubika insinga, nibicuruzwa bya siporo. Bitewe no guhangana kwayo, TPU ifite abrasion nyinshi nimbaraga zo gukata kandi irashobora gukoreshwa mubidukikije byinshi. Nyamara, izwiho gukuramo ubuhehere buturuka mu kirere, bigatuma bigorana gutunganya mugihe cyo kubyara. Kubumba inshinge, hariho reberi ya termoplastique (TPR), ihendutse kandi yoroshye kuyikoresha, nko gukora reberi ikurura.
Niba igice cyawe gisaba lens cyangwa Windows isobanutse, acrylic (PMMA) nibyiza. Kubera ubukana bwayo no kurwanya abrasion, ibi bikoresho bikoreshwa mugukora amadirishya adasenyuka nka plexiglass. PMMA nayo isize neza, ifite imbaraga zingana, kandi irahenze kubyara umusaruro mwinshi. Ariko, ntabwo ari ingaruka cyangwa imiti irwanya polyikarubone (PC).
Niba umushinga wawe usaba ibikoresho bikomeye, PC irakomeye kuruta PMMA kandi ifite ibyiza bya optique, bigatuma ihitamo neza kuri lens na windows idafite amasasu. PC irashobora kandi kugororwa no gushingwa mubushyuhe bwicyumba itavunitse. Ibi ni ingirakamaro kuri prototyping kuko bidasaba ibikoresho bihenze kugirango bibeho. PC ihenze kuruta acrylic, kandi kumara igihe kinini kumazi ashyushye birashobora kurekura imiti yangiza, kubwibyo ntabwo yujuje ubuziranenge bwibiribwa. Bitewe n'ingaruka zayo no kurwanya ibishushanyo, PC nibyiza kubikorwa bitandukanye. Kuri Star Rapid, dukoresha ibi bikoresho kugirango dukore amazu ya Muller Commercial Solutions handldinal terminal. Igice cyari CNC yakozwe mumashanyarazi akomeye ya PC; kubera ko yari ikeneye kuba mucyo rwose, yashizwemo intoki hamwe na parike.
Ubu ni incamake muri make ya plastike ikoreshwa cyane mubikorwa. Byinshi muribi birashobora guhindurwa hamwe nibirahuri bitandukanye byikirahure, UV stabilisateur, amavuta yo kwisiga cyangwa ibindi bisigazwa kugirango ugere kubisobanuro runaka.
Gordon Stiles nuwashinze akaba na perezida wa Star Rapid, prototyping yihuse, ibikoresho byihuse hamwe nisosiyete ikora inganda nkeya. Ashingiye ku buhanga bwe, Stiles yashinze Star Rapid mu 2005 kandi ayoboye isosiyete imaze kugera ku bakozi 250. Star Rapid ikoresha itsinda mpuzamahanga ryaba injeniyeri nabatekinisiye bahuza ikoranabuhanga rigezweho nko gucapisha 3D hamwe na CNC imashini nyinshi hamwe nubuhanga gakondo bwo gukora nibipimo byiza. Mbere yo kwinjira muri Star Rapid, Styles yari ifite kandi ikora STYLES RPD, isosiyete nini yo mu Bwongereza yihuta cyane kandi ikoresha ibikoresho, yagurishijwe muri ARRK Europe mu 2000.
