Makina osindikizira a 3D a SLA / DLP amapereka ndondomeko yapamwamba kwambiri
Anthu osindikizira a 3D 3D omwe amagwiritsidwa ntchito masiku ano amagwiritsira ntchito njira yosungiramo mavoti (FDM), omwe amatchedwa extruder, otentha kwambiri, monga momwe amatchulidwira nthawi zambiri, kusungunula ma polymer (pulasitiki). Palinso gulu lina limene likukula mofulumira monga makina osindikizira a desktop.
Ojambula a 3D resin amagwiritsa ntchito stereolithography (SLA) kapena kuunika kwa digito (DLP) monga njira yapadera yomwe amapangira zigawo. M'malo mosungunula kapangidwe ka pulasitiki, omasulirawa amagwiritsa ntchito kuwala pofuna kuchiritsa puloteni yamoto yosavuta kumva.
Ambiri osindikizira aficionados amanena kuti zipangizo za DLP / SLA zimapereka chisankho chabwino komanso chokhalitsa, koma ndondomeko ya 3d yosindikizira imakhala yowonjezereka. Komabe, makina osindikizira a DLP ndi SLA onse amasindikiza mofulumira kuposa osindikizira omwe amawamasulira. M'zaka zingapo zapitazo, tawona ambiri osindikiza a FDM 3D akuyamba kudzera mwa crowdfunding. Tsopano tikuwona makina osindikiza 3d ku Kickstarter ndi IndieGoGo, mwachitsanzo.
Chifukwa chakuti osindikiza a DLP ndi SLA onse amagwiritsa ntchito photopolymers omwe amaumitsa powaunika kuwala kwa UV, utomoniwu umasinthasintha nthawi zambiri mwa osindikiza awa. Izi zikhoza kutsutsana, ndithudi, ndi opanga omwe akufuna kuti muzigwiritsa ntchito resins okha. Muyenera kusamala kuti musayese ndondomeko yanu, kuti mukhale omveka, popeza sindikudziwa bwino mawu awa. Werengani zolemba zabwino!
Ndi makina osindikizira a 3D osungirako zinthu, pali mitundu itatu ya masitini - ofanana, otchinga, ndi osinthika. Ndimazitcha resinins, koma mudzapeza ambiri opanga utomoni amawatcha "zitsulo zapamwamba" kapena "resin high resolution".
- Zolemba zapamwamba zowonjezera zimapereka mitundu yosiyanasiyana ya mitundu. Mwachitsanzo, Formlabs amapereka izi momveka, zoyera, zakuda, kapena zakuda. Gawo la Amazon Additive Manufacturing Products la "3D Printer Store" yawo limapanga mitundu yosiyanasiyana ya mitundu kuchokera ku MadeSolid ndi MakerJuice.
- Masamba opangidwa ndi MadeSolid amagwiritsidwa ntchito poponyera. Masambawa samasiya phulusa, zomwe zimapangitsa kuti zikhale zoyenera kuika ndalama. Icho chilinso ndi kukula kwakukulu ndi kuwonongeka mpaka kutentha kwenikweni. Zili ndi malingaliro amtengo wapatali ndipo zingagwiritsidwe ntchito ndi ndondomeko zambiri za kutentha zomwe zimagwiritsidwa ntchito ndi omwe amapanga ndalama zodzikongoletsera. Asiga ikugwiritsanso ntchito SuperWAX, yomwe imagwiritsa ntchito mapuloteni omwe angagwiritsidwe ntchito poponya platinamu.
- Ngati mukufuna kupanga chithunzithunzi chomwe chikufunikira mphamvu yoposa mphamvu yamadzi, MakeSolid imapereka Vorex. Pakalipano, imapezeka mu lalanje kapena lakuda, koma pamene mphamvu yake ikutha ndi kuchulukana kwake, imafuna mphamvu yochulukirapo kusiyana ndi ma resin. Chokhazikikacho chinalenga kuti chikhale chokhalitsa komanso kusakanikirana.
- Ma resin ena amapereka kutentha kwakukulu, monga Accura Bluestone ndi SOMOS 9120 (yomwe imakhalanso ndi mankhwala osagwira ntchito) kuchokera ku Proto3000 kapena Asiga's FusionGRAY. Ambiri amadzimadzi amatha kutenthedwa kutenthedwa kwambiri kuti apange zowonongeka, zopangidwa ndi mphira komanso kugwiritsa ntchito mafakitale.
- Popeza kusindikiza kwa 3D kumagwiritsidwanso ntchito ndi makampani azachipatala kuti apange zipangizo zamagetsi zodziwika bwino, kufunikira kwa kusinthasintha madzi ndibwino. Kupanga Resin Flexible Resin ndi SJ Makerice Zuice zogwiritsira ntchito mankhwalawa zimakhala zosasintha pamene achiritsidwa. Asiga's Bio Range photopolymer resin imathandizanso. Chifukwa cha kutengeka kwa khungu, zinthu monga zothandizira kumva zimayenera kupangidwa kuchokera kuzipinda zapadera. Asiga akufuna kulola kuti mapepala asindikizidwe omwe sangasokoneze khungu ngakhale pamene chipangizochi chimasokoneza tsiku lonse.
- Autodesk anakhazikitsa makina osindikizira a Ember 3D. Iwo akupanga zipangizo zawo, Standard Prototyping Resin (PR48) ndi dzina, koma mungagwiritse ntchito ma resin ena ndi printer yawo.
Apanso, nkofunika kuyang'ana mogwirizana ndi makina anu osindikizira musanagule resin. Komabe, zambiri za resinzi zinapangidwa kuti zigwiritsidwe ntchito mu printer iliyonse ya 3D yomwe imagwiritsa ntchito mazira a UV pofuna kuchiza utomoni wamadzi.
Ma resin ena amafuna zina zowuchiritsira pakutha pamene zasindikizidwa, koma izi zimapangitsa kuti ntchito yomalizira ikhale yaitali. Ngakhale kuti SLA ndi DLP 3D zosindikizira zipangizo sizinafikire kusiyana komwe amaperekedwa ndi osindikizira extrusion, akadali mitundu yambiri, ndipo zipangizo zambiri zili panjira.
