Zvinyorwa zvingakubatsira kuti uone kuti ndezvipi zvakakonzerwa nejekiti yako yeD 3D
Iyo envelopu inopisa yakauya uye mukati yaiva duku duku ye 3D yakatumirwa ibhola yakadhindwa naMorris Technologies (yakawanikwa neG GE Aviation). Terry Wohlers, mumwe wevanyori vepamusoro ekudhinda kwe 3D, akazvitumira kwandiri kuratidzira kuti simba re 3D rakadhindwa sei rinogona kuva. Akaudzwa kuti ichi chakanaka, chiedza-kunzwa, bhora rakatarisa rakange rakasimba zvokuti iwe unogona kumira pairi.
Iko yakasimba zvakakwana here? Ndiyo mubvunzo unowanzobvunzwa nevanhu pamusoro pekupedzisira kweD 3D chinhu chakadhindwa, kazhinji.
Mupfungwa dzangu, sezvo zvichida kune vamwe vanofunga, ndiri kushamisika kana ini ndikatora nguva, mari, nekuedza kushandura 3D chimwe chinhu-chichava chakasimba sechigadzirwa chandinogona kutenga-chifufu? Uyu mubvunzo wakanaka.
Vanhu vakawanda vanobvunza uye vazhinji vanodikanwa uye vari kuedza simba remashoko. Vakawanda vavo vane masayendisiti, saiyo iyo ndakasangana nayo pa Ford Motor Company yekuyera kuenzanisa zvakasiyana-siyana zve 3D zvakadhindwa nekupinza mukati mavo ne X chiyero chekurema. Kufara basa iro rinofanira kuva, kuedza kuputsa pfungwa. Kupfekedza magirazi ako ekudzivirira.
Unhu hwehuTube, Thomas Sanladerer, unoita mavhidhiyo nguva dzose pamusoro pekudhinda kwe 3D kunonzi chete: Tom kana Tom's Guide. Akaita zvaaifarira zvekudhinda 3D test material test iwe unogona kutarisa pano.
Saka, kutema kumhanya, simba haisi nyore nguva dzose kuzvitsanangura - zvinobva pane zvauri kuita nayo mushure mokunge iwe uchidhinda. Uri kuinyorera here? Chimbomira chimwe chinhu kubva pairi? Inofanirwa here kumirisana nemagetsi kana kupisa?
Chimwe chezvinhu zvakanakisisa zvekushandisa kupindura mamwe emibvunzo iyi inowanika paCAPUniversity - iyo ibhuku rinonyorwa neSolidworks reseller muNortheast USA. Mumahofisi avo, andinokukurudzira kuti uende uverenge: Kusarudza Zvinyorwa Zvako zvekudhinda zve 3D: Zviri pamusoro pezvakawanda kupfuura simba!
Vanotsanangura simba rezvinhu zvakajairika: ABS, PLA, Nylon nevamwe.
Ndinopa zvigadzirwa zvemashandiro e ABS uye PLA pano . Heino imwe inobva kuCAPUniversity yakabva kune simba rakasimba - yakaderera kusvika kune yakakwirira.
| ABS | 33MPa (4,700 psi) |
| Nylon | 48MPa (7,000 psi) |
| PLA | 50MPa (7,250 psi) |
| PC | 68MPa (9 800 psi) |
| PEI | 81MPa (11,735 psi) |
ABS, PLA, uye Nylononi zvakajairika zvekudhinda zve 3D.
PC inomiririra polycarbonate uye ndeye yepamusoro-shandiswa yakashandiswa nemabhizimisi thermoplastics, asi haunzwi nezvevanhu vakawanda vanoishandisa muFff / FDM type 3D printers. The RepRap Wikihas ine peji yakanaka inotsanangura zvimwe zvezvakanaka uye zvinotapira polycarbonate.
PEI is Polyetherimide (PEI) resin, asi zita rakakurumbira rekutengeserana ndiro Ultem. Ultem imhuri yemiti yePI yakagadzirwa naSABIC semugumisiro wekuwana General Electric Plastics Division muna 2007. Sezvaunogona kuona mu chati, ine simba rakakwirira kwazvo.
Imwe nyanzvi iStatasys, iyo yakabudisa PDF: Thermoplastics: Simba Rakasimba Pakudhindwa Kwema 3D. Ndiwo mapeji matanhatu chete, uye anotarirwa kune zvinhu zvinoshandiswa kuStatasys printers, hongu, asi yakanaka kune mamwe mabhii maFused Deposition Modeling (FDM); nzira yavakapayona nayo.
Gwaro rekupedzisira: Dzokera kuTitanium Ball: Handiyeuki kana Terry Wohlers akandiudza izvi kana kwete, asi ndakafunga kuti achiseka achiti aizotumira kwandiri kana ndikabvuma kumira pairi. Akati akange asina mwoyo wekupwanya bhora duku, maererano nehukuru hwemarble marble, asi kana ndakabvuma kuti aizoenda nayo kwandiri. Ndakati ndaizoita zvachose, asi pazvaisvika ndakanga ndisina mwoyo wokumira pazviri, kana! Icho chiri chinyanyiso chaizvo kuti chigadzikane, kana vaiti vanga vasina kururama pamusoro pekuedza kwavo simba.
