Igisabo Kinyeganyega cy'Ingendo Eshatu: Umwanya Uzamuka Ukamanuka Uha Igisukamo Ingendo Eshatu kuri Buri Kunyeganyega

"Umupfundikizo umaze gukandwa hasi, ikadiri inyeganyega E ihabwa urugendo hakoreshejwe ifatiro I, kandi uko ikadiri inyeganyega igice gihuza gifite utuziga tw'ubushyamirane kigenda mu myanya D, na F, giha igisukamo ingendo eshatu zitandukanye, bityo bigatera amata kuvangwa cyane kuri buri kunyeganyega cyangwa guhindagurika kw'ikibindi cy'amavuta mbisi kurusha uko bikorwa n'indi mashini yose y'ubwo bwoko."

Capa ibyuma bibiri by'umwanya, igice gifite utuziga n'utuziga tubiri. Capa muri PETG ku byiciro bya mm 0.2, kuzuza 30 %, inkuta 4; oza mbere yo gukoresha bwa mbere.

Ubaka ikadiri ya A ya pine ifite uburebure bwa mm 520 nk'ayo, amaguru abiri kuri buri ruhande, maze umanike ikadiri inyeganyega y'inkingi ebyiri za pine n'urubaho rwo hasi ku nkoni ya mm 10 hejuru, ifatiro rya pine risohoka ku rubaho rwayo rwo hasi. Fatisha icyuma cy'umwanya ukoresheje bolt imbere ya buri jambo ry'amaguru kugira ngo hagati h'umwanya wacyo habe kuri mm 300 munsi y'ishingiro.

Shinga igikoresho cy'ibiryo ku rubaho rwo hasi rw'inyeganyega. Sunika inkoni y'igisukamo ya dowel ya mm 10 inyure mu myanya iri mu nkingi z'inyeganyega yinjire mu mwobo w'igice gifite utuziga, utuziga turi ku mitambiko yatwo migufi mu byuma by'umwanya, maze ufatishe igisukamo cya pine gifite imyobo ku kirenge cyayo imbere mu gikoresho.

Reka amavuta mbisi y'ibinure bigeze kuri 15 °C nk'ayo, ubirebe na termometero. Suka litiro 1.5 maze ushyireho umupfundikizo. Nyeganyeza ikadiri neza ukoresheje ifatiro; igisukamo kigenda inshuro eshatu kuri buri cyerekezo. Bara igihe kugeza amavuta aje. Suka amacunda, ongeramo amazi akonje, cunda gato maze wongere usuke kugeza asohotse asukuye; vangamo umunyu muke maze upime amavuta.

Ntiyasabye igisabo kinyeganyega, cyangwa ingendo zirenze imwe kuri buri kunyeganyega ubwazo; yasabye ibice bigoramye bidasanzwe bigize umwanya uzamuka ukamanuka hamwe n'ikadiri inyeganyega ifite imyanya n'igice gihuza gifite utuziga. Imiraba n'ingano by'umwanya wacu ni ibyacu; igishushanyo cye nta na kimwe gitanga. Ibicapwa bya FDM bigumana ibiryo mu mirongo y'ibyiciro byabyo, bityo ubyoze neza maze ubisimbuze iyo bishaje.
