Abacwaningi benze uhlelo oluyinkimbinkimbi olukwazi ukuphrinta izakhiwo ezincane nge-3D ngesivinini esikhulu kakhulu.
Kukhona abathengisi abambalwa abahlinzeka ngokuphrinta kwe-3D nge-microscopic namuhla, kodwa labo abavumela ukukhiqizwa kwamadivayisi amangalisayo amancane kakhulu, amalensi, nezingxenye. Abaningi basebenzisa lokho okubizwa ngokuthi “i-two-photon” indlela, lapho ukukhanya kugxile ekujuleni kwe-photopolymer ewuketshezi ukuze kuqiniswe into, i-voxel nge-voxel.
Inkinga ukuthi isivinini sokuphrinta okunjalo kwe-3D singahamba kancane, njengoba indawo okugxilwe kuyo yesistimu yama-photon amabili kufanele inqamule ngokukhathazayo sonke isakhiwo. Abacwaningi bafuna indlela yokwenza lolu hlobo lokuphrinta kwe-3D ngendlela eshesha kakhulu.
Ukuphrinta kwe-Multifocus 2PP 3D
Bagcina sebesungula uhlelo oluyinkimbinkimbi kakhulu oluboniswe ngenhla. Kunzima ukukulandela, kodwa empeleni i-laser (ibhokisi eliphezulu kwesokunxele elikhipha i-80MHz 790nm beam) ithumela amandla ngochungechunge lwama-prism, izibuko, izihlukanisi ukudala "i-fan of beamlets". Ekugcineni, lezi zifika kupheya yezibuko ze-galvanometric ezingu-6mm kwesokudla, ezibhalwe ukuthi “GX” kanye “GY”.
Izibuko ze-galvo zisebenza kuze kufike ku-2.8 kHz ukuze zisabalalise ama-beamlet ezindaweni ezifunwayo endaweni yokuskena. Ngokusobala izibuko zinyakaziswa ngokushesha, abacwaningi kwadingeka bakhe isimiso sokupholisa amanzi ukuze baqinisekise ukuthi azishisi ngokweqile!
Ngokuyisisekelo, kubonakala sengathi baklame isistimu yokuvumela ukuphrinta kwe-3D okufanayo kusetshenziswa inqubo yama-photon amabili. Lena impumelelo impela. Babiza inqubo ngokuthi “Multifocus 2PP”.
Isivinini se-Multifocus 2PP
Abacwaningi bakwazile ukuphrinta nge-3D inani lezinto zesampula besebenzisa inqubo entsha, okuhlanganisa nama-metamaterials, okungaba isicelo esiyinhloko salobu buchwepheshe.
Ishesha kangakanani inqubo entsha? Abacwaningi bakwazile ukuzuza isivinini esimangalisayo sama-voxel ayizigidi eziyishumi ngomzuzwana - lapho i-3D iphrinta ngosayizi we-voxel we-sub-micrometer. Nakuba ekugcineni amaphrinti e-3D enziwa kusetshenziswa le nqubo kuzoba mancane ngokomzimba, isivinini sokukhiqiza cishe asikholeki.
Cabanga ukuthi lesi sivinini singaphinda siphindeke kumaphrinti kasayizi omkhulu we-3D. Isibonelo, umfanekiso we-100mm ungase udle u-6m we-filament noma cishe u-14,500 cubic mm wento. Uma ubukade uphrinta le nto nge-3D ngokulungiswa okungu-0.1mm, lokhu bekuzomela okuthile okusondele kuma-voxels angu-14.5M.
Uma lenyuswa izinga, le sistimu ingakhiqiza le nto ngamasekhondi angu-1.5 nje. Kunjalo, ngeke kukhuliswe kuze kufike kulelo zinga, ngokwazi kwami.
Kodwa ngiyaphupha.
