Khatiso ea 3D e fetotse tlhahiso, e nolofalletsa ho theha likarolo tse rarahaneng le tse ikhethileng. Leha ho le joalo, ho finyella ho nepahala le ho sebetsa hantle ha khatiso ea 3D ho hloka likarolo tse tsoetseng pele tsa optical. Lilense tsa F-Theta li bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso ea litsamaiso tsa khatiso tsa 3D tse thehiloeng ho laser.

Ho utloisisa F-Theta Lenses

Lilense tsa F-Theta ke lilense tse khethehileng tse etselitsoeng ho fana ka sebaka se bataletseng sa ho tsepamisa maikutlo holim'a sebaka se itseng sa ho skena. Hangata li sebelisoa lits'ebetsong tsa laser scanning, ho kenyelletsa le tse sebelisoang khatisong ea 3D. Tšobotsi e ikhethang ea lilense tsa F-Theta ke hore sebaka ho tloha ho lense ho ea sebakeng se tsepamisitsoeng se lekana le sekhutlo sa ho skena. Thepa ena e netefatsa boholo bo tsitsitseng ba sebaka le sebopeho ho pholletsa le sebaka sa scanning.

Melemo ea Bohlokoa bakeng sa Khatiso ea 3D

Ntlafatso ea Precision:

Lilense tsa F-Theta li fana ka boholo bo tšoanang ba letheba la laser le sebopeho, tse netefatsang kabo e tsitsitseng ea matla sebakeng sa khatiso.

Ho lumellana hona ho fetolela ho nepahala le ho nepahala ha likarolo tse hatisitsoeng.

Keketseho ea Katleho:

Sebaka se bataletseng sa ho tsepamisa maikutlo se fanoeng ke lilense tsa F-Theta se lumella ho potlakisa lebelo la ho hlahloba, ho fokotsa nako ea khatiso le ho eketseha ha tlhahiso.

Ts'ebetso ena e bohlokoa haholo bakeng sa tlhahiso e kholo le lits'ebetso tsa indasteri.

Uniformity e ntlafetseng:

Ka ho boloka letheba la laser le sa fetoheng, lilense tsa F-Theta li netefatsa ho beoa ha thepa e ts'oanang le botenya ba lera, e hlahisang likhatiso tsa boleng bo holimo.

Sena se bohlokoa haholo bakeng sa lits'ebetso tse kang Selective Laser Sintering(SLS) kapa Stereolithography (SLA) 3D printers.

Sebaka se Seholo sa Scanning:

Lilense tsa F-Theta li ka etsoa ho fana ka sebaka se seholoanyane sa ho hlahloba, se nolofalletsang tlhahiso ea likarolo tse kholoanyane kapa likarolo tse ngata mosebetsing o le mong oa khatiso.

Lisebelisoa ho Khatiso ea 3D

Lilense tsa F-Theta li sebelisoa haholo mahlaleng a fapaneng a khatiso a 3D a thehiloeng ho laser, ho kenyelletsa:

Selective Laser Sintering (SLS): Lilense tsa F-Theta li tataisa lebone la laser ho sinter lisebelisoa tsa phofo ka lera.

Stereolithography (SLA): Ba tsamaisa lebone la laser ho phekola resin ea metsi, ho theha likarolo tse tiileng.

Laser Direct Deposition (LDD): Lilense tsa F-Theta li laola lebone la laser ho qhibiliha le ho beha phofo ea tšepe, ho etsa meaho e rarahaneng.

Lilense tsa F-Theta ke likarolo tsa bohlokoa haholo lits'ebetsong tsa khatiso tsa 3D tse thehiloeng ho laser, tse kenyang letsoho ho ntlafatseng ho nepahala, ho sebetsa hantle le ho tšoana. Lintho tsa bona tse ikhethang li etsa hore ho be le likarolo tsa boleng bo phahameng tse nang le li-geometri tse rarahaneng.

Bakeng sa ba batlang lilense tsa boleng bo holimo tsa F-Theta bakeng sa khatiso ea 3D,Laser ea Carman Haase fana ka mefuta e mengata ea likarolo tse nepahetseng tsa optical. Rea u amohela ho ikopanya le rona!
