Tekinoroji nyowani dzekudhinda dze3D dziri kuvandudzwa nekukurumidza zvekuti zviri nyore kufungidzira ramangwana riri pedyo umo pasina chero chinhu chisingakwanise kudhindwa 3D.
Huwandu hwezvinhu zviripo ndechimwe chezvipingamupinyi zvakakosha kugamuchirwa kweindasitiri 3D kudhinda.Kudhinda kwe 3D kuri kukurumidza kugamuchirwa nevagadziri vezvigadzirwa pasi rese, asi haisati ichikwanisa kukwikwidzana nedzimwe nzira dzakawanda dzekugadzira zvine chekuita nekusiyana kwezvinhu.Nhamba huru yeanonyanya kushandiswa mapurasitiki emuindasitiri haasati awanikwa zvakanyanya kumaprinta e3D, zvichiita kuti kudhinda kwe3D kusakodzere maapplication akawanda.
PTFE (polytetrafluoroethylene) chinhu chinobatsira zvakanyanya, chinoshandiswa muzvigadzirwa zvemazuva ese.Iyo yakanyanya hydrophobic, zvichireva kuti hapana mvura kana zvinhu zvine mvura zvinoita kuti inyorove, saka inoshandiswa muzvipfeko zvekunze.Iyo ine zvakare imwe yeakaderera friction coefficients chero yakasimba.Ndiyo chete nzvimbo isingagone kunamira pairi.Ichi chivakwa chinoita kuti ive yakakwana kune isiri-tsvimbo yekupfeka yebakeware.Utachiona uye humwe hutachiona zvakare hune nguva yakaoma kwazvo yekuomerera kune izvo zvinhu, zvichiita kuti ive sarudzo yakanaka kune dzakasiyana siyana dzekushandisa muchipatara, senge catheter.
Mamwe mafluoropolymers anoshandiswawo zvakanyanya mumafuta uye gasi, makemikari, emotokari uye aerospace maindasitiri, uye zvinogoneka kuti imwecheteyo 3D yekudhinda tekinoroji inogona kuiswa kwavari.Kubudirira uku kunoita kuti zvikwanise kudhinda 3D kirasi nyowani yezvishandiso, iyo ichapesvedzera maindasitiri mazhinji.
Kazhinji, zvikamu zvinogadzirwa kubva kuPTFE uye mamwe mafluoropolymers anogadzirwa achishandisa anodhura echinyakare maitiro ekugadzirisa, ayo anowanzo kugadzira marara akawanda.Izvo zvakaomawo kugadzira zvimiro zvakaoma zvikuru.3D kudhindaine mukana wekupa kugadzirwa kwakasimba uye kwakasiyana kwakasiyana magadzirirwo.Kubudirira kwave kutogadzira nzira yezvaimbove zvisingaite zvikumbiro.
Fluorinated polymers, aka fluoropolymers, anogona kunge asina kunaka semadhaimani, asi iwo chinhu chakakosha mumaitiro mazhinji ekugadzira.Iyo fluorocarbon-based plastics inosiyaniswa nekusimba kwayo kwepamusoro-kuita uye kuramba kumakemikari ane hutsinye uye tembiricha yakakwira.Inoshandiswa mune zvese kubva mumhepo uye zvekudzivirira zvikumbiro kune isiri-tsvimbo yekubikira nzvimbo, mafluoropolymers ari kwese kwese - kunze kwemaprinta e3D.
Izvo zvinogona kuchinja munguva pfupi, zvakadaro, sezvo kambani yekuvandudza zvigadzirwa 3M yakaisa patent yemhando nyowani ye 3D yekudhinda tekinoroji iyo inobvumira kugadzirwa kwekuwedzera kwemapolima akazara fluorinated.Tekinoroji inozoreva kuti zvimiro zvakaomarara zvinogona kugadzirwa nekukurumidza uye zvakachipa, nepo zvikamu zvakafanana zvichiwanzo kudhura zvakanyanya kugadzira nedzimwe nzira dzekugadzira.
Kunyange paine akati wandei emhando dzefluorinated polymers, pamwe iyo inonyanya kubatsira kubva ku3D kudhinda ndeye polytetrafluoroethylene kana PTFE, inonyanya kuzivikanwa sepolymer.PTFE, iyo inowanzoshandiswa mumashandisirwo akadai sekuisa chisimbiso uye lining, inogadzira tsvina yakawanda mukugadzira.3D kudhinda iyo - iyo 3M ichave yekutanga kuita - ichacheka zvakanyanya kumashure pamarara iwayo.Pamusoro pezvo, makambani anotora mukana wekuita izvi achakwanisa kugadzira akaomesesa, akawanda-chikamu mapolymer zvimiro muchidimbu chimwe chete pane kuumba nekuunganidza zvikamu zvakawanda.
