Isu tinowanzo gamuchira nhau nezve zvakasarudzika kudhindwa senge zvipfeko kana chikafu, asi kufambira mberi kuri kuitwawo mune dzimwe nzvimbo senge maindasitiri. A) Hongu mainjiniya akakwanisa kudhinda injini yeToyota ine Prusa.
Iye injinjiniya anonzi Eric Harrell, makanika aifarira kudhinda kwe 3D uye akaona kuti kugadzirwa kweinjini kwaingogadzirirwa makambani makuru chete ayo nemishini yavo mikuru anokwanisa kupurinda zvikamu zvakaoma kudaro.
Achida kutyora aya mazano, Eric Harrell akaburuka kushanda uye pakati peThingiverse repository neruzivo rwake akagadzira zvikamu zvakafanira uye dhizaini yekugona kudhinda injini yeToyota, kunyanya iyo Toyota 4 Cylinder Injini 22RE injini.
Kunyangwe iwo marongero eprojekti aya aive akaomarara, mhedzisiro sezvaungaona mumifananidzo yakanaka. Uye zvakare, iyi injini yese yakangopedza 1. Kg. Yezvinhu zvePLA, ngatione izvo zvinouya kuva paki yePLA mune chero chitoro. Nezve kudhindwa kwezvidimbu, Harrell akataura kuti chirongwa ichi chakatora maawa makumi manomwe nemaviri kudhinda uye maawa makumi matanhatu kugadzira zvidimbu. Injini yakazara ine zvikamu zvinopfuura makumi masere.
Injini yeToyota inoumbwa nezvikamu makumi masere uye yadya 80 kg. by PLA
Harrell akaisa zvese zvigadzirwa zveinjiniya zveToyota mukati chinhu uye anoyambira kuti kunyangwe ichigona kuitwa neyakajairika Prusa, muprinta anofanirwa kuongororwa kazhinji kuitira kuti calibration yakaipa isagadzire chikamu chakaremara.
Kunyangwe pachezvangu ini ndisingazive kuti injini yepurasitiki inogona kushanda zvakadii mumota yakajairwa, chirongwa ichi chinonakidza nekuti chinogona kutibvumidza kusevha mazana emazana emauros ane zvikamu zvakagadzirwa zvakanyanya izvo mota huru dzemota dzinobhadharisa chidimbu chegoridhe uye icho nemari isingasviki makumi maviri nemana euros (ndiwo mutengo wepakati paiyo kirogiramu yePLA) tinogona kugadzirisa matambudziko aya.
