Umgangatho ogqwesileyo waseTshayina Jpt Mopa Umbala weFayibha Umsiki weLaser uRaycus Max Ipg 20W 30W 50W weMetal wokuMakisha uMzobo wokuSika umatshini

Abashicileli beFilament 3D balungile, kodwa baqhele ukulinganiselwa kubungakanani.Abashicileli beLaser sintering babonelela ngeebhedi ezinkulu zoshicilelo, kodwa bakwaphatha ithegi yexabiso le $250,000. Kufuneka senze ntoni? Kulungile, enkosi kwi-OpenSLS, kuyenzeka ukujika i-laser yakho. umatshini wokusika kwiprinta yakho ye-SLS 3D.
Siye sazisa i-OpenSLS ngamaxesha amaninzi ngaphambili, kodwa kubonakala ngathi ekugqibeleni ibe sisisombululo esipheleleyo (kwaye sisebenziseka).Kutshanje ipapashe inqaku lophando malunga nomthombo ovulekileyo okhethiweyo we-laser sintering (OpenSLS0 yenylon kunye ne-polycaprolactone ye-biocompatible (PDF)), eneenkcukacha. uyilo kunye nolwakhiwo.
Iqela lenze i-hardware ekwazi ukuguqula i-laser cutter kunye nobukhulu bebhedi ye-60 cm x 90 cm ibe yi-SLS printer.beauty?Ininzi ye-hardware ye-laser cut, oku kuthetha ukuba unakho ukuguqula i-laser cutter ibe yiprinta ye-3D.
Iifayile zoyilo zingafumaneka kwi-GitHub yazo.I-hardware inokubiza malunga ne-$ 2,000, eyi-peanuts xa kuthelekiswa nomshicileli we-laser sintered yorhwebo.Kukho ulwazi oluninzi kumanqaku abo-asikwazi ukugubungela ulwazi oluninzi kwinqaku elinye. Ukuba ekugqibeleni uyakha enye, nceda usazise!
Kuya kufuneka ndicofe kwelinye lamakhonkco ukufumanisa ukuba bathetha ngantoni. Ndiyabuza, yintoni i-SLS kuqala? kwisakhiwo esiqinileyo se-3D. "
Ndifuna ukwazi ukuba ngaba kunokwenzeka ukusebenzisa i-alloys yensimbi ephantsi yokunyibilika. Ndiyazi ukuba i-SLS enkulu yokuthengisa i-drilling rigs ingasebenzisa i-aluminium okanye intsimbi, kodwa indawo yokunyibilika kwezinye izinyithi ezimhlophe kufuneka ibe phakathi koluhlu lwee-laser cutting machines.
Nangona kunjalo, isinyithi ngokubanzi sibonakalisa ngakumbi kwaye sisebenza ngokushushu kuneplastiki, ke nangona ndilindele ukuba isebenze, kunokuba lula ukufaka ubushushu ngokuthe ngqo, njengerobhothi ye-3D ye-welding echazwe yi-hackaday kunyaka ophelileyo http://hackaday.com/ 2015/06/13/6-axis-robot-arm-3d-prints-a-metal-bridge/
Ewe, ezinye iiyunithi zoshishino zisebenzisa i-laser sintering ngale ndlela, ngoko kunokwenziwa.Isalathisi sokubonisa ezininzi zesinyithi ezinomgubo zikwinqanaba elifanayo nesalathiso sokubonisa iiplastiki ezinomgubo.Ukongezelela, kukho ezininzi i-zinc alloys kunye neMP enengqiqo. kufuneka ibe phakathi koluhlu lwemishini yokusika i-laser.Umbuzo wokwenyani ngulo, ndiyacinga ukuba ezi ngxubevange zizinto eziluncedo zokuvelisa.
Isiphelo sangaphambili sezixhobo zoshishino ngokuqhelekileyo sine-polarizing optics ukufunxa okanye ukuguqula umqadi obonakalisiweyo kude nomthombo we-laser.Okwangoku, le meko ayikho nge-CO2 lasers.Ukongezelela, ngaphandle kokuba kukho i-argon efanelekileyo yokuzaliswa okanye i-vacuum kwi-enclosure. , uninzi lwezinyithi luya ku-oxidize kuphela (okanye lutshise) .Ubunzima kunye neendleko zokucutshungulwa kwesinyithi zanda ngokukhawuleza.
Le nto uyibhalileyo yinyani, yiyo loo nto ndiye ndacinga ukusebenzisa intsimbi enkonkxiweyo okanye ialloyi yokubrawuza enokwenzeka kubushushu obufanelekileyo.
Ndiza kuzama i-alloys ye-brazing.Ndicinga ukuba baya kubonelela ngezona ziphumo zihle kakhulu kunye nethuba elincinci letyhefu yensimbi.
Umfanekiso we-OLD_HACK ufanelekile ukuba uqaphele: i-laser eluhlaza okwesibhakabhaka. Kwisinyithi esingenanto, i-spectrum yokufunxa iya kusebenza ngakumbi kune-CO2 laser. Oku kuthetha ukuba i-beam encinci ibonakaliswe kwi-laser kwaye ngoko ingazinzanga.

Kule meko, i-wavelength ayinamsebenzi.Utshintsho kwiimpawu zokufunxa kwesinyithi kwi-wavelength range ye-400nm ukuya kwi-10um akwanelanga ukudlala indima apha.Uphawu olubaluleke ngakumbi lubonakaliso ngenxa yokunyuka komphezulu kunye nomgangatho.Xa kuthelekiswa ngomphezulu ongaqhelekanga, umphezulu othe tyaba unokubonakalisa ukukhanya okungaphezulu ubuyele kumphezulu.
I-laser ye-Diode ivakalelwa ngakumbi kwi-back reflections.Ukuphela kokulimala kobuso, ukungazinzi kwe-wavelength, kunye notshintsho lwesakhiwo se-beam iphethini inokuthi yenzeke.Ukuzihlukanisa kweFaraday kungasetyenziselwa ukunciphisa le ngxaki enokubakho.
Iilaser zegesi (ezifana ne-CO2 lasers ezibandakanyekayo apha) aziyi konakala ngokubonakaliswa ngasemva.Ngapha koko, obu buchule bunokusetyenziselwa ukwenza injongo yokutshintsha kwe-Q ukufezekisa amandla amakhulu e-pulse peak.
Mhlawumbi sebenzisa i-Nd: i-lasers ye-YAG, i-ytterbium fiber lasers okanye i-laser efanayo, edla ngokusetyenziselwa ukusika isinyithi endaweni yokusebenzisa i-CO2 lasers. njengeplastiki), kodwa ayiyi kuba nayiphi na impembelelo kwintsimbi.
Buthini ubungakanani bamasuntswana eplastiki yokuqala? Ndiyathemba ukuba inkulu kwaye ayinako ukusasazeka emoyeni, kuba ukuba amasuntswana eplastiki angena emoyeni aze anamathele kwisibuko sakho, kwilensi, nakwi-coupler ephumayo, kungekudala uya kuba nosuku olubi. .
Ukuze kuncitshiswe le meko, i-optics kufuneka ibe yodwa ngokupheleleyo "kwindawo yokusebenza" ukukhusela umgubo weplastiki ukuba ungangeni.
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
Ndicinga ukuba i-laser sintering joints iya kuba yinto epholileyo-akukho phepha elifunekayo! Ngaba unokubonelela ngemathiriyeli?
Kulungile, andinakukunika yona.LeOku kunokuba ngumbono olungileyo kwiNetherlands.Kodwa ndiyazi ukuba abanye abantu benze iphepha le-sintered, kunye neswekile edibeneyo kunye nesquick.
Ngokusebenzisa iwebhusayithi yethu kunye neenkonzo, uvumelana ngokucacileyo nokubekwa kwenkqubo yethu, ukusebenza kunye neekuki zentengiso. Funda ngakumbi
