Le ha ts'ebetso ea khale ea fused deposition molding (FDM) e na le melemo ea tlhaho tlhahisong ea likarolo tse rarahaneng tsa sebopeho, likarolo tse entsoeng ka theknoloji ena li ntse li na le mathata a ho hloka matla a lekaneng le ho hanyetsa mocheso o tlase.

Ho eketsa matla a sehlahisoa, ts'ebeliso ea lisebelisoa tse bobebe, matla a phahameng a matlafatsoang ke mokhoa o sebetsang haholo. Bafuputsi ba bang ba kopantse likhoele tse hahiloeng ka har'a thepa ea lehoakhoa le mehala e matlafalitsoeng bakeng sa FDM. Leha ts'ebetso e tloaelehileng ea FDM e futsitsoeng ke likhoele tse matlafalitsoeng tse nang le fiber e na le monyetla oa ho theha likarolo tse rarahaneng tsa geomorphic, ntlafatso ea matla a sehlahisoa ha e totobetse haholo, 'me ha e khone ho fihlela litlhoko tse phahameng tsa matla tseo re li lebelletseng . Ha li bapisoa le lisebelisoa tse matlafalitsoeng tsa fiber, lisebelisoa tse matlafatsoang tsa fiber li ka eketsa matla a sehlahisoa haholo, empa ka lebaka la khaello e tsoelang pele ea fiber, mokhoa oa ho bōpa o na le ho haelloa ke bokhoni ba ho theha likarolo tse rarahaneng tsa sebopeho.

Bakeng sa ho rarolla bothata bo boletsoeng kaholimo ba fiber e tsoelang pele e matlafalitsoeng, bafuputsi MY le YK ba tsoang sekolong se phahameng sa Japane ba ikhethang ka ho rala le ho etsa mofuta o mocha oa molomo oa extrusion (Setšoantšo sa 1).

Ho fapana le lisebelisoa tse matlafatsoang tsa fiber tse tsoelang pele, nozzle e sebelisa lisebelisoa tse peli tsa fepa ho laola phepelo ea terata e tsoelang pele ea khalase ea fiber le terata e eketsehileng ea lehoakhoa. Khoele e tsoelang pele ea fiber e matlafalitsoeng eo ba e sebelisang ke terata e entsoeng ka fiber e koahetsoeng ka PA6 e nang le bophara ba 0.3 mm, moo boleng ba khalase ea carbon fiber Vf e laoloang ho 50%, 'me lisebelisoa tse ling tsa lehoakhoa ke nylon 645. E le' ngoe Karolo ea karolo e ka tlase ea lera le le leng ke fiber e tsoelang pele e matlafatsang thepa ea thermoplastic, 'me karolo e kaholimo ke lisebelisoa tse ling tsa lehoakhoa. Joalokaha ho ka bonoa setšoantšong, lisebelisoa tse ling tsa lehoakhoa li ka etsa matlafatso ea fiber. Gully ea thepa e fokotsa tlhahiso ea likheo nakong ea khatiso.

Ntle le moo, MY le YK ba sebelisitse lisebelisoa tse ntlafalitsoeng ke bona ho hlophisa mehlala e thata mme ba etsa liteko tse thata. Liphetho tsa liteko li bonts'itse hore module ea E elastic ea lisampole e fihlile ho 53 Gpa, karolelano ea Poisson γ 0.39, le matla a tensile tb 701 MPa.

Ho latela maikutlo a MY le YK, ba ile ba hakanya hore boteng ba masoba a kahare karolong e le 'ngoe ea karolo e bopehileng bo bile le phello e kholo ho thepa ea sehlahisoa, mme ho nahanoa hore hamorao ba ile ba etsa qeto ea ts'ebetso ea kalafo ea mocheso ho latela mofuta oa thepa ho futhumatsa sampole. Le khatello e chesang ho felisa porosity e kahare. Liphetho li bonts'itse hore kalafo ea mocheso ha ea ka ea ntlafatsa haholo matla a khatello ea sampole (20%), empa sampole kamora ho hatella ho chesang e imenne habeli ka elastic elastic le tensile matla ha e bapisoa le sampole e sa alafshoang. Bafuputsi ba lumela hore ts'ebetso e chesang ea ho hatella e tlosa masoba ho monolayer mme e baka keketseho e kholo ho thepa ea sehlahisoa.
