Kune zviuru zvemapurasitiki pamusika wekukurumidza prototyping kana diki-scale kugadzirwa - kusarudza iyo purasitiki yakakodzera kune imwe purojekiti inogona kukurira, kunyanya kune vanoshuvira vanogadzira kana vanoda mabhizinesi. Chinhu chimwe nechimwe chinomiririra kuwirirana maererano nemutengo, simba, kuchinjika uye kupera kwepamusoro. Izvo zvinodikanwa kufunga kwete chete kushandiswa kwechikamu kana chigadzirwa, asiwo nharaunda iyo ichashandiswa.
Kazhinji, mapurasitiki einjiniya akavandudza zvivakwa zvemuchina izvo zvinopa kusimba kwakanyanya uye hazvishanduke panguva yekugadzira. Mamwe marudzi emapurasitiki anogonawo kuchinjwa kuti avandudze simba rawo, pamwe chete nemigumisiro uye kupisa kwekudzivirira. Ngatinyure mune akasiyana epurasitiki zvinhu zvekufunga zvinoenderana nekushanda kwechikamu chekupedzisira kana chigadzirwa.
Imwe yeanonyanya kushandiswa resin anoshandiswa kugadzira mekiniki zvikamu naironi, inozivikanwawo se polyamide (PA). Kana polyamide yakasanganiswa ne molybdenum, ine nzvimbo yakatsetseka kuitira nyore kufamba. Nekudaro, magiya enylon-on-nylon haakurudzirwe nekuti, semapurasitiki, anowanzo kunamatira pamwechete. PA ine yakakwira kupfeka uye abrasion kuramba, uye yakanaka michina zvivakwa pakupisa kwakanyanya. Nylon chinhu chakanakira 3D kudhinda nepurasitiki, asi inotora mvura nekufamba kwenguva.
Polyoxymethylene (POM) zvakare isarudzo yakanakisa yezvikamu zvemakanika. POM is acetal resin inoshandiswa kugadzira DuPont's Delrin, purasitiki yakakosha inoshandiswa mumagiya, screws, mavhiri nezvimwe. POM ine yakakwirira flexural uye tensile simba, rigidity uye kuoma. Zvisinei, POM yakasvibiswa nealkali, chlorine nemvura inopisa, uye zvakaoma kunamatira pamwechete.
Kana purojekiti yako iri imwe mhando yemudziyo, polypropylene (PP) ndiyo yakanakisa sarudzo. Polypropylene inoshandiswa mumidziyo yekuchengetera chikafu nekuti inodzivirira kupisa, haipindirwe nemafuta uye zvinonyungudutsa, uye haiburitse makemikari, zvichiita kuti zvive zvakachengeteka kudya. Polypropylene zvakare ine yakanakisa chiyero chekuomarara uye kusimba kwesimba, zvichiita kuti zvive nyore kugadzira zvishwe zvinogona kukotama kakawanda pasina kutyoka. Inogonawo kushandiswa mumapombi uye hoses.
Imwe nzira ndeye polyethylene (PE). PE ndiyo ipurasitiki yakajairika munyika ine simba rakaderera, kuoma uye kuoma. Kazhinji ipurasitiki chena ine mukaka inoshandiswa kugadzira mabhodhoro emishonga, mukaka nemidziyo yekugezesa. Polyethylene inoshingirira zvakanyanya kumhando dzakasiyana-siyana dzemakemikari asi ine nzvimbo yakaderera yekunyungudika.
Acrylonitrile butadiene styrene (ABS) zvinhu zvakanakira chero purojekiti inoda kukwirira kupikisa uye kukwirira kwemisodzi nekutsemuka. ABS haina huremu uye inogona kusimbiswa nefiberglass. Inodhura kupfuura styrene, asi inogara kwenguva refu nekuda kwekuoma kwayo uye simba. Fusion-yakaumbwa ABS 3D modhi yekukurumidza prototyping.
Tichifunga nezvezvimiro zvayo, ABS isarudzo yakanaka yezvipfeko. PaStar Rapid, takagadzira smartwatch kesi yeE3design tichishandisa jekiseni rakaumbwa dema pre-yakapendwa ABS/PC plastiki. Iyi sarudzo yemidziyo inoita kuti mudziyo wese ureruke, ukuwo uchipa kesi inogona kumira apo neapo kuvhunduka, senge kana wachi ichirova nzvimbo yakaoma. Yakakwirira maitiro polystyrene (HIPS) isarudzo yakanaka kana iwe uchida zvinhu zvakasiyana-siyana uye zvinodzivirira zvinhu. Ichi chinyorwa chakakodzera kugadzira maturusi emagetsi macasi uye makesi emidziyo. Kunyangwe maHIPS achitengeka, haaonekwe seane hushamwari kwezvakatipoteredza.
Mapurojekiti mazhinji anodaidzira majekiseni ekuumba resin ane elasticity senge rabha. Thermoplastic polyurethane (TPU) isarudzo yakanaka nekuti ine akawanda akakosha maumbirwo epamusoro elasticity, yakaderera tembiricha kuita uye kusimba. TPU inoshandiswawo mumaturusi emagetsi, rollers, cable insulation, uye zvinhu zvemitambo. Nekuda kwekuramba kwayo kunyungudutsa, TPU ine yakakwira abrasion uye shear simba uye inogona kushandiswa munzvimbo dzakawanda dzeindasitiri. Nekudaro, inozivikanwa nekutora hunyoro kubva mumhepo, zvichiita kuti zviome kugadzirisa panguva yekugadzira. Pakuumba jekiseni, pane thermoplastic rabha (TPR), isingadhure uye iri nyore kubata, sekugadzira mabatiro erabha anobata kuvhundutsa.
Kana chikamu chako chichida lenzi dzakajeka kana mahwindo, acrylic (PMMA) ndiyo yakanakisisa. Nekuda kwekuomarara kwayo uye abrasion kuramba, chinhu ichi chinoshandiswa kugadzira shatterproof windows senge plexiglass. PMMA zvakare inokwenenzvera zvakanaka, ine simba rakanaka rekusimba, uye inodhura inoshanda pakugadzira vhoriyamu yakakwirira. Nekudaro, haina kukanganiswa kana kemikari inodzivirira se polycarbonate (PC).
Kana purojekiti yako ichida chinhu chakasimba, PC ine simba kupfuura PMMA uye ine yakanakisa optical zvivakwa, zvichiita kuti ive sarudzo yakakodzera yemalenzi uye mahwindo emabulletproof. PC inogona zvakare kukotama uye kuumbwa pakamuri tembiricha pasina kutyora. Izvi zvinobatsira kune prototyping nekuti haidi inodhura mold maturusi kuumba. PC inodhura kupfuura acrylic, uye kuratidzwa kwenguva refu kumvura inopisa kunogona kuburitsa makemikari anokuvadza, saka haaenderane nekuchengetedza chikafu. Nekuda kwekukanganisa kwayo uye kuramba kukwenya, PC yakanakira akasiyana ekushandisa. PaStar Rapid, tinoshandisa zvinhu izvi kugadzira dzimba dzeMuller Commercial Solutions dzinobata ruoko. Chikamu chacho chaive CNC yakagadzirwa kubva kune yakasimba block yePC; sezvo yaida kunyatsojeka, yaichekwa nejecha nemaoko uye yakakwenenzverwa utsi.
Iyi ingori pfupiso yemamwe mapurasitiki anonyanya kushandiswa mukugadzira. Zvizhinji zveizvi zvinogona kugadziridzwa neakasiyana girazi fibers, UV stabilizers, lubricant kana mamwe maresin kuti uwane mamwe maitiro.
Gordon Stiles ndiye muvambi uye mutungamiri weStar Rapid, inokurumidza prototyping, inokurumidza maturusi uye yakaderera vhoriyamu yekugadzira kambani. Zvichienderana nemamiriro ake einjiniya, Stiles akatanga Star Rapid muna 2005 uye pasi pehutungamiriri hwake kambani yakakura kusvika kuvashandi ve250. Star Rapid inoshandisa timu yepasirese yeinjiniya uye matekinoroji anosanganisa matekinoroji ekucheka-cheka senge 3D kudhinda uye CNC akawanda-axis machining nemaitiro echinyakare ekugadzira uye emhando yepamusoro zviyero. Asati ajoinha Star Rapid, masitaera aive uye akashanda STYLES RPD, iyo UK yakakura nekukurumidza prototyping uye tooling kambani, iyo yakatengeswa kuARK Europe muna 2000.
