Ukusuka ku-ABS kuya ku-PLA kuya ku-ceramic noma kwensimbi ye-powders, nansi uhlu lwezinto ze-3D
Isayensi yezinto ezibonakalayo iyoba yinto ekhethekile yokufunwa ngokunyuka kwe-3D Printing. Uma uzwa mayelana namaphrinta e-3D, uvame ukuzwa ngokunyathelisa epulasitiki, kodwa kunezinqwaba, uma kungenamakhulu, izinto ongazisebenzisa ku-printer ye-3D.
Izinto zokuprinta ze-thermoplastic 3D
Izakhiwo ze-ABS (Acrylonitrile Butadiene Styrene):
- ABS Ukushisa Okushisa 240 ° C noma 464 ° F
- Kuyisisekelo se-petroleum esekelwe
- I-ABS idinga umbhede oshisayo noma indawo yokwakha evuthayo, ukuze uhambisane nesakhiwo sokwakha ngendlela ezinzile, okusho ukuthi ngeke ivule noma ikhuphuke iphinde isuse kwipulatifomu yokwakha. Abanye abantu basebenzisa i-kapton tape epulatifomu evuthayo ukudala ukunamathela kahle nokuvimbela ukulwa, kodwa abanye basebenzisa amathrekhi epulasitiki ahlanzekile afana nekhasi le-Teflon.
- ABS iveza izinto ezinzima, eziqinile. Lokhu akusho ukuthi akukwazi ukuphulwa, kungaba, kodwa kuvame ukuhlanganiswa nezinye izinto, njenge-carbon fiber, okwenza kube namandla kakhulu.
- Itholakala ngemibala ehlukahlukene
- I-ABS ingabuyekezwa kabusha / ishintshwe, i-granulated bese iphinda iphinde iphinde ibe yi-filament futhi
- I-ABS ingase iphunga njengeplastiki ecibilikile kune-PLA futhi kunconywa ukuba usebenzise iphrinta yakho endaweni enomoya ogcwele kahle.
Izakhiwo ze-PLA (Polylactic acid):
- PLA Ukushisa Okushisa 180 ° C noma 356 ° F
- Yenziwe emithonjeni evuselelwe, njenge-starch yembewu noma umoba
- I-PLA ayidingi umbhede oshisayo
- I-PLA ivela ngemibala ehlukahlukene, kufaka phakathi izinhlamvu ezicacile, eziguquguqukayo.
- Izinto eziphrintiwe ku-PLA azizona eziqinile noma ezinamandla njenge-ABS
- Nakuba kwenziwa emithonjeni evuselelekayo, empeleni kunzima ukuphinda uphinde usebenzise kabusha i-ABS
Izakhiwo ze-nylon (Polyamide):
- Kunezinhlobonhlobo zama-nyloni, ngakho-ke ngibhekisela iNylon 618, enye yamamaki ajwayelekile amaphrinta e-3D, okwamanje.
- Inayiloni 618 iyancibilika ngo-242 ° C noma i-464 ° F
- Ayidingi i-Kapton tape, kodwa inezakhiwo ezifanayo ku-ABS ngoba ipholisa ngokushesha emaphethelweni, okwenza kube nokungazinzeki okuzokwenza ukuba kuqedwe isiteji sokwakha.
- Ayikho imfucumfucu eyingozi uma ishicilelwe kumazinga okushisa anconywayo, kodwa isanconywa ukuba isebenze endaweni enomoya ophuthumayo.
- Lighter kuno-ABS noma i-PLA
- Inikeza ubuso obusheshayo uma udala amalunga noma amakolishi adinga ukushelela kalula
I-Metal 3D Printing Powders
Ngensimbi eningi enephuzu eliqhakazile elingaphezu kuka-500 C noma i-1,000 F, ungabona ukuthi kungani izinsimbi ze-3D zensimbi zibiza, futhi zingase zibe yingozi, uma zingasetshenziswa kahle. I-American Society for Testing and Materials (ASTM) yaziwa kahle futhi ikhiqiza amazinga ukuphepha kanye nekhwalithi. Basanda kudedela enye yokukhiqiza okungeziwe, ngokukhethekile ngamapuldidi ensimbi, ongayilanda (imali) noma ufunde kancane ngakho lapha.
Ama-powders ensimbi nawo ayabiza kakhulu. Amanye ama-powders avamile engiwabonayo noma awafunde ngokufaka:
- Ama-alloys ensimbi
- Titanium alloys
- Ama-alloys e-Cobalt Chrome
- Insimbi engagqwali
- Aluminium
I-Ceramic ne-Glass ye-3D Izinto Zokuphrinta
I-Sculpteo, ihhovisi lezinsizakalo zokunyathelisa le-3D, liprinta nge-ceramic nge-printer Z Corp 3D.
I-Shapeways isanda kukhishwa izinto zayo ze-ceramics futhi yethulwa ngeperecelain yokushicilela kwe-3D, njengento entsha. Kubonakala kumnandi futhi ungafunda ngakho lapha.
Ukunyathelisa kwe-3D ngezinto zokudla
Kukhona abantu abaqeda iphrinta yabo ye-3D yedeskithophu ukuphrinta nge-chocolate, ne-broccoli, nokuxuba kwe-frosting yekhekhe, ukubiza ezimbalwa. Angiqinisekisi okwamanje ukuthi ezinye zazo zizonambitha okuhle, kodwa ngivulekile ukuhlola ...
Ukufuna izindaba ze-3D zokushicilela izindaba noma izibuyekezo
Ngizoqhubeka ngengeza kulezi zinto izinto ezenziwe ngukushicilela i-fact sheet eveza ama polymeri amasha, ama-resin amasha, ama-alloys ensimbi, i-ceramics nesilazi, futhi noma yikuphi imikhiqizo emisha ehlasela imakethe yokunyathelisa ye-3D. Njengoba ngishilo kwezinye izikhalazo, izinkampani ezifana ne-Proto-pasta, zikhiqiza ama-polymeri ahlukahlukene, ukuhlanganisa izinto ezintsha ne-ABS noma i-PLA ukukhiqiza umkhiqizo omusha ngokuphelele.
Thola ukuthintana uma unezinto okufanele ngizifake lapha: Hamba ekhasini lami le-Bio lapho ngigcina yonke imininingwane yami yokuxhumana kusesikhathini.
