Kune zviuru zvemapurasitiki ari kutengeswa kuti ashandiswe nekukurumidza kana kuti padiki - kusarudza mapurasitiki akakodzera purojekiti chaiyo kunogona kunetsa, kunyanya kune vanoda kutanga kana vanoda kutanga mabhizinesi. Chinhu chimwe nechimwe chinomiririra kubvumirana maererano nemutengo, simba, kuchinjika uye kupenya kwechinhu. Zvakakosha kufunga kwete chete nezvekushandiswa kwechikamu kana chigadzirwa, asiwo nharaunda yachichashandiswa.
Kazhinji, mapurasitiki einjiniya ane hunhu hwakanaka hwemakanika hunopa kugara kwenguva refu uye haachinje panguva yekugadzira. Mamwe marudzi emapurasitiki anogonawo kugadziriswa kuti awedzere simba rawo, pamwe nekudzivirira kupisa uye kusimba kwekupisa. Ngationgororei zvinhu zvakasiyana-siyana zvepurasitiki zvekufunga nezvazvo zvichienderana nekushanda kwechikamu chekupedzisira kana chigadzirwa.
Imwe yemaresini anonyanya kushandiswa kugadzira zvikamu zvemakanika inylon, inozivikanwawo sepolyamide (PA). Kana polyamide ikasanganiswa nemolybdenum, ine pamusoro wakatsetseka kuti ive nyore kufamba. Zvisinei, magiya enylon-on-nylon haakurudzirwi nekuti, semapurasitiki, anowanzo batana. PA ine simba rekudzivirira kubvaruka nekukwesha, uye ine hunhu hwakanaka hwemakanika pakupisa kwakanyanya. Nylon chinhu chakanakira kudhinda kwe3D nepurasitiki, asi inonwisa mvura nekufamba kwenguva.
Polyoxymethylene (POM) isarudzo yakanakawo yezvikamu zvemakanika. POM ipurasitiki yeacetal inoshandiswa kugadzira DuPont's Delrin, ipurasitiki inokosha inoshandiswa mumagiya, masikuruu, mavhiri nezvimwewo. POM ine simba guru rekugonya nekudhonza, kuomarara uye kuomarara. Zvisinei, POM inokanganiswa nealkali, chlorine nemvura inopisa, uye inonetsa kunamira pamwe chete.
Kana chirongwa chako chiri chemhando yemudziyo, polypropylene (PP) ndiyo sarudzo yakanakisisa. Polypropylene inoshandiswa mumidziyo yekuchengetera chikafu nekuti haipindi kupisa, haipindi mafuta nezvinonyungudutsa, uye haiburitse makemikari, zvichiita kuti ive yakachengeteka kudya. Polypropylene ine chiyero chakanaka chekuomarara uye simba rekukanganisa, zvichiita kuti zvive nyore kugadzira zvishwe zvinogona kukotama kakawanda pasina kutyoka. Inogona zvakare kushandiswa mumapaipi nemapombi.
Imwe sarudzo ipolyethylene (PE). PE ndiyo purasitiki inonyanya kushandiswa pasi rose ine simba shoma, kuomarara uye kuomarara. Kazhinji ipurasitiki chena yakaita semukaka inoshandiswa kugadzira mabhodhoro emishonga, midziyo yemukaka neyekushambidza. Polyethylene inodzivirira zvakanyanya makemikari akasiyana-siyana asi ine poindi shoma yekunyunguduka.
Zvinhu zveAcrylonitrile butadiene styrene (ABS) zvakanakira chero basa rinoda kuramba kusimba uye kuramba kubvaruka nekupwanyika zvakanyanya. ABS yakareruka uye inogona kusimbiswa nefiberglass. Inodhura kupfuura styrene, asi inogara kwenguva refu nekuda kwekuoma kwayo uye kusimba kwayo. Fusion-molded ABS 3D modeling yekukurumidza kugadzira prototyping.
Zvichienderana nehunyanzvi hwayo, ABS isarudzo yakanaka yezvipfeko zvinopfekwa. KuStar Rapid, takagadzira kadhi resmartwatch reE3design tichishandisa injection molded black pre-painted ABS/PC plastic. Sarudzo iyi yezvinhu inoita kuti mudziyo wese uve wakareruka, ukuwo uchipa kadhi rinogona kutsungirira dzimwe nguva kuvhunduka, senge kana wachi ikarova panzvimbo yakaoma. High impact polystyrene (HIPS) isarudzo yakanaka kana uchida zvinhu zvinoshanduka-shanduka uye zvinodzivirira kukuvadzwa. Izvi zvinhu zvakakodzera kugadzira mabhokisi emagetsi nemabhokisi ezvishandiso akasimba. Kunyangwe maHIPS achikwanisika, haaonekwe seasina njodzi kune zvakatipoteredza.
Mapurojekiti mazhinji anoda maresini ekuumba majekiseni ane kusimba kwakaita serabha. Thermoplastic polyurethane (TPU) isarudzo yakanaka nekuti ine akawanda maformula akakosha ekusasimba kwakanyanya, kushanda kwakaderera uye kugara kwenguva refu. TPU inoshandiswawo muzvishandiso zvemagetsi, maroller, tambo dzinodzivirira kusvibiswa, uye zvinhu zvemitambo. Nekuda kwekusasimba kwayo kwe solvent, TPU ine simba rakawanda rekukwenya uye kuchekwa uye inogona kushandiswa munzvimbo dzakawanda dzemaindasitiri. Zvisinei, inozivikanwa nekunwisa hunyoro kubva mumhepo, zvichiita kuti zviome kugadzira panguva yekugadzira. Kune injection molding, kune thermoplastic rabber (TPR), iyo isingadhuri uye iri nyore kubata, senge yekugadzira rabha dzinobata shock-absorbing.
Kana chikamu chako chichida magirazi akajeka kana mahwindo, acrylic (PMMA) ndiyo yakanakisisa. Nekuda kwekuoma kwayo uye kuramba kukwesha, chinhu ichi chinoshandiswa kugadzira mahwindo asingaputsike akadai seplexiglass. PMMA inopenya zvakanaka, ine simba rakanaka rekukwesha, uye inodhura zvishoma pakugadzira zvakawanda. Zvisinei, haina kubatwa kana makemikari zvakanyanya sepolycarbonate (PC).
Kana purojekiti yako ichida chinhu chakasimba, PC yakasimba kupfuura PMMA uye ine hunhu hwakanaka hwemaziso, zvichiita kuti ive sarudzo yakakodzera malenzi nemahwindo asingapindi bulletproof. PC inogonawo kukotama uye kugadzirwa patembiricha yemukamuri isina kutyoka. Izvi zvinobatsira pakugadzira prototyping nekuti haidi maturusi anodhura emold kuti iumbwe. PC inodhura kupfuura acrylic, uye kugara mumvura inopisa kwenguva refu kunogona kuburitsa makemikari anokuvadza, saka haisviki pamitemo yekuchengetedza chikafu. Nekuda kwekukanganisa kwayo uye kuramba kwayo kukwenya, PC yakakodzera kushandiswa kwakasiyana-siyana. KuStar Rapid, tinoshandisa chinhu ichi kugadzira dzimba dzeMuller Commercial Solutions handheld terminals. Chikamu chacho chakagadzirwa neCNC kubva paPC yakasimba; sezvo chaida kujeka zvakakwana, chakachekwa nemaoko uye chakaporishwa nemhepo.
Iyi ingori pfupiso yemamwe mapurasitiki anonyanya kushandiswa mukugadzira. Mazhinji acho anogona kuchinjwa negirazi rakasiyana, UV stabilizers, mafuta kana mamwe maresini kuti awane mamwe magadzirirwo.
Gordon Stiles ndiye muvambi uye mutungamiri weStar Rapid, kambani inogadzira maprototype nekukurumidza, maturusi nekukurumidza uye kugadzira zvinhu zvishoma. Zvichibva paruzivo rwake rweinjiniya, Stiles akatanga Star Rapid muna 2005 uye pasi pehutungamiriri hwake kambani iyi yakakura kusvika pavashandi mazana maviri nemakumi mashanu. Star Rapid inoshandisa timu yepasi rose yemainjiniya nematekiniki vanosanganisa matekinoroji epamusoro akadai sekudhinda kwe3D uye CNC multi-axis machining nehunyanzvi hwekugadzira hwechinyakare uye mwero wepamusoro. Vasati vajoina Star Rapid, Styles yaive neSTYLES RPD, kambani hombe muUK yekugadzira maprototype nekukurumidza uye kugadzira zvinhu, iyo yakatengeswa kuARRK Europe muna 2000.
