Amaphrinta e-Filament 3D mahle, kodwa ngokuvamile anosayizi olinganiselwe.Amaphrinta we-Laser sintering ahlinzeka ngemibhede emikhulu yokuphrinta, kodwa futhi aphatha ithegi yenani lika-$250,000. Kufanele senzeni?Hhayi-ke, ngenxa ye-OpenSLS, kuyenzeka ukuthi uvule i-laser yakho. umshini wokusika ube eyakho iphrinta ye-SLS 3D.
Sethule i-OpenSLS izikhathi eziningi ngaphambili, kodwa kubukeka sengathi ekugcineni isiyisixazululo esiphelele (futhi esisebenzisekayo).Muva nje ishicilele isihloko socwaningo mayelana ne-open source selective laser sintering (OpenSLS0 of inayiloni kanye ne-biocompatible polycaprolactone (PDF)), enemininingwane. umklamo kanye nesakhiwo.
Ithimba lidale izingxenyekazi zekhompuyutha ezingashintsha i-laser cutter enosayizi wombhede ongu-60 cm x 90 cm ibe yiphrinta ye-SLS.ubuhle?Izingxenyekazi eziningi zekhompuyutha zisikwa nge-laser, okusho ukuthi usungakwazi kakade ukuguqula i-laser cutter ibe iphrinta ye-3D.
Amafayela omklamo angatholakala ku-GitHub yawo.Izingxenyekazi zekhompuyutha zingakubiza cishe u-$2,000, okungamakinati uma kuqhathaniswa nephrinta ye-laser sintered yokuhweba.Kunolwazi oluningi ezihlokweni zabo-asikwazi ukumboza ulwazi oluningi esihlokweni esisodwa. Uma ekugcineni wakha eyodwa, sicela usazise!
Kufanele ngichofoze enye yezixhumanisi ukuze ngithole ukuthi bakhuluma ngani.Ngiyabuza, yini i-SLS kuqala?Lol “I-Selective Laser Sintering (SLS) iwuhlelo lokukhiqiza olwengeziwe olusebenzisa i-laser ukuhlanganisa izinto ezingavuthiwe eziyimpuphu. singene esakhiweni esiqinile se-3D.”
Ngifuna ukwazi ukuthi kungenzeka yini ukusebenzisa ama-alloys ensimbi ancibilika aphansi.Ngiyazi ukuthi izinsimbi zokumba ezinkulu ze-SLS zokuhweba zingasebenzisa i-aluminium noma ngisho nensimbi, kodwa indawo yokuncibilika kwezinye izinsimbi ezimhlophe kufanele ibe ngaphakathi kwebanga lemishini yokusika i-laser.
Kodwa-ke, insimbi ngokuvamile icwebezela kakhulu futhi i-thermal conductive kunepulasitiki, ngakho-ke nakuba ngilindele ukuthi isebenze, kungase kube lula ukufaka ukushisa ngokuqondile, njengerobhothi lokushisela le-3D elibikwe yi-hackaday ngonyaka odlule http://hackaday.com/ 2015/06/13/6-axis-robot-arm-3d-prints-a-metal-bridge/
Nokho, amanye amayunithi ezimboni asebenzisa i-laser sintering ngale ndlela, ngakho-ke kungenziwa.Inkomba yokubonisa yezinsimbi eziningi eziyimpushana isebangeni elifanayo nenkomba yokubonisa yamapulasitiki ayimpuphu.Ngaphezu kwalokho, kunama-alloys amaningi e-zinc aneMP enengqondo ukuthi kufanele ibe phakathi kwemishini yokusika i-laser.Umbuzo wangempela uwukuthi, ngicabanga, ukuthi lezi zingxubevange ziyizinto zokukhiqiza eziwusizo.
Ingxenye engaphambili yemishini yezimboni ivamise ukuba ne-polarizing optics ukuze imunce noma ichezukise i-beam ebonisiwe isuke emthonjeni we-laser.Okwamanje, lesi simo asikho ngamalaser e-CO2.Ngaphezu kwalokho, ngaphandle uma kukhona ukugcwaliswa okuhle kwe-argon noma i-vacuum endaweni ebiyelwe. , izinsimbi eziningi zizokhipha i-oxidize kuphela (noma zishise).Ubunzima nezindleko zokucubungula insimbi zikhula ngokushesha.
Okubhalile kuyiqiniso, yingakho ngicabange ukusebenzisa insimbi ekheniwe noma ingxubevange yokufaka insimbi engenzeka ezingeni lokushisa elifanele.
Ngizozama ama-alloys e-brazing.Ngicabanga ukuthi azohlinzeka ngemiphumela engcono kakhulu nethuba elincane kakhulu lobuthi bensimbi.
Isithombe se-OLD_HACK kufanelekile ukunakwa: i-laser eluhlaza okwesibhakabhaka.Ngensimbi engenalutho, i-spectrum yokumuncwa izosebenza kangcono kune-CO2 laser.Lokhu kusho futhi ukuthi i-beam encane kakhulu iboniswa emuva ku-laser ngakho-ke ayizinzile.

Kulokhu, ubude begagasi abunandaba.Ushintsho ezicini zokumuncwa kwezinsimbi kububanzi be-wavelength obungu-400nm ukuya ku-10um akwanele ukudlala indima lapha.Isici esibaluleke kakhulu ukubukeka okubonakalayo ngenxa yokucaba kwendawo kanye nekhwalithi.Uma kuqhathaniswa ngendawo engavamile, indawo eyisicaba ingabonisa ukukhanya okwengeziwe kubuyele phezulu.
Amalaser e-Diode azwela kakhulu ekukhanyeni okungemuva.Ukulimala kobuso ekugcineni, ukungazinzi kwe-wavelength, kanye nezinguquko zephethini ye-beam kungenzeka.Ukuhlukaniswa kwe-Faraday kungasetshenziswa ukudambisa le nkinga engaba khona.
Amalaser egesi (njengamalaser e-CO2 ahilelekile lapha) ngeke alinyazwe ukuboniswa kwangemuva.Eqinisweni, le nqubo ingasetshenziswa ukwenza ngenhloso ukushintsha i-Q ukuze kuzuzwe amandla amakhulu okushaya ngamandla.
Mhlawumbe sebenzisa ama-laser e-Nd:YAG, ama-laser e-ytterbium fiber noma ama-laser afanayo, avame ukusetshenziselwa ukusika izinsimbi esikhundleni sokusebenzisa ama-laser e-CO2. Kulawa mazinga wamandla aphansi angu-~50W, i-laser engu-10um evela kulaser ye-CO2 imuncwa kahle izinto eziphilayo (organic material). njengepulasitiki), kodwa ngeke ibe nomthelela ensimbi.
Ungakanani usayizi wezinhlayiyana zento yokuqala yepulasitiki? Ngethemba ukuthi inkulu futhi ayikwazi ukusabalala emoyeni, ngoba uma izinhlayiya zepulasitiki zingena emoyeni futhi zinamathele esibukweni sakho, ilensi, kanye ne-coupler ephumayo, maduze uzoba nosuku olubi. .
Ukuze kuncishiswe lesi simo, i-optics kufanele ihlukaniswe ngokuphelele "endaweni yokusebenza" ukuvimbela i-powder yepulasitiki ukuthi ingangeni.
Hi, just to tell you this is good news!!The company I work for, we produce and manufacture powders for SLS PA12, PA11, TPU, and polycaprolactone and waxes for sls.I really think this is the technology of the future!!If you need customized sls materials, please feel free to contact me!marga.bardeci@advanc3dmaterials.com
Ngicabanga ukuthi amajoyinti e-laser sintering angaba mnandi ngaphandle kwephepha elidingekayo! Ungakwazi yini ukuhlinzeka ngezinto zokwakha?
Nokho, angikwazi ukukunikeza yona.Lokhu
Lokhu kungase kube umqondo omuhle eNetherlands
.Kodwa ngiyazi ukuthi abanye abantu benze iphepha eline-sintered, kanye noshukela osikiwe kanye nesquick.
Ngokusebenzisa iwebhusayithi yethu namasevisi, uvumelana ngokucacile nokubekwa kwamakhukhi ethu okusebenza, ukusebenza kanye nokukhangisa.Funda kabanzi
