PLA gbalẽvi siwo gblẽna le nugbagbeviwo ŋu dede kaɖiwo wɔwɔ ƒe ɖoɖowo me fia be wotsɔ wo ɖokui na be yewoawɔ nusiwo li tegbee. To nusiwo megblẽa nu le nutome ŋu o tiatia me la, asitsalawo kpea asi ɖe agbagba si wodzena le xexeame katã le avuwɔwɔ kple nutome ƒe gbegblẽ me.
Zi geɖe la, kaɖi siwo wozãna tsã la naa ɖiƒoƒo kple gbeɖuɖɔwo ƒoa ƒu. Gake to PLA ƒe agbalẽviwo xɔxɔ me la, dɔwɔƒewo xɔa mɔnu si me womezãa amagbewo le o, si wɔnɛ be nu gbegblẽ siwo wògblẽna ɖe nutome ŋu dzi ɖena kpɔtɔna.
Esi yame ƒe nɔnɔme ƒe tɔtrɔ ƒe ŋɔdzidoname si gbɔna ta la, nyametsotso ɖesiaɖe le vevie. To PLA ƒe agbalẽviwo zazã me la, asitsalawo wɔa nu do ŋgɔ le nutome takpɔkpɔ me na dzidzime siwo gbɔna.
Le ɣeyiɣi si me dɔwɔƒewo ƒe hadomegbanɔamedziwo xɔ aƒe ɖe eme la, PLA ƒe agbalẽviwo nyea bubu ƒe dzesi na adzɔnuwɔƒe siwo tsɔ wo ɖokui na be yewoawɔ nusiwo li tegbee. To ɖekawɔwɔ kple nuwɔna siwo tsia dzi ɖe nutome ŋu me la, asitsalawo doa ŋusẽ woƒe adzɔnu ƒe ŋkɔ eye wohea nuƒlela siwo tsia dzi ɖe nutome ŋu.
Esi dziɖuɖuwo le se siwo ku ɖe nutome takpɔkpɔ ŋu me sẽm le xexeame katã la, PLA ƒe agbalẽviwo naa egbɔkpɔnu si wɔ ɖeka kple seawo na dɔwɔƒe siwo di be yewoawɔ ɖe dzidzenu sesẽwo dzi. To nusiwo woate ŋu azã si li tegbee xɔxɔ me la, dɔwɔƒewo ɖea afɔku si le sedzimawɔmawɔ me dzi kpɔtɔna eye wokpɔa egbɔ be woate ŋu awɔ dɔ ɣeyiɣi didi.
Tso dzigbezã didiwo dzi va ɖo ŋkekenyui ƒe gbedonamewo dzi la, PLA ƒe agbalẽwo sɔ nyuie na gbedonamegbalẽvi siwo me gblẽa nu le nutome ŋu o la wɔwɔ. Woƒe akpa si le gbadzaa kple alesi woate ŋu ata woe na wosɔ nyuie na atsyã siwo gɔme sese sesẽ kple gbedasi siwo tso dzime ɖeɖefia.
Le dɔwɔƒewo ƒe xexeame la, amewo ƒe nukpɔsusu gbãtɔ le vevie. PLA-gbalẽ siwo gblẽna le nugbagbeviwo ŋu naa mɔnu bubu si li tegbee ɖe plastik-dɔwɔgbalẽvi xoxowo teƒe, si gblẽa nu nyui aɖe ɖe asisi kple hadɔwɔla siwo tsia dzi ɖe nutome ŋu.
Le nunana gome la, nuƒoƒoe nye nu vevitɔ. PLA ƒe agbalẽviwo doa nunanagbalẽviwo ƒe nu lédziname ɖe ŋgɔ kple woƒe ɖaseɖigbalẽ siwo me gblẽa nu le nutome ŋu o, si naa asixɔxɔ nɔa nunana ƒe nuteƒekpɔkpɔ bliboa ŋu esime wòɖea ŋusẽkpɔɖeamedzi ɖe nutome dzi dzi kpɔtɔna.
To vovo na agbalẽvi siwo wotu ɖe PVC alo PET dzi, siwo hea afɔku gã aɖe vɛ na nutome la, PLA-gbadzɛwo nye esiwo woate ŋu atsɔ awɔ gbeɖuɖɔe eye woate ŋu agblẽ nu le nugbagbewo ŋu. Wotsɔa mɔnu bubu si me amagbewo bɔ ɖo o naa amewo evɔ womegblẽa nu le eƒe nyonyome alo dɔwɔwɔ ŋu o.
Togbɔ be ga si woxena do ŋgɔ ate ŋu asɔ gbɔ vie na PLA-gbalẽviwo ne wotsɔe sɔ kple nusiwo wozãna tsã hã la, viɖe siwo wokpɔna le nutome ŋu ɣeyiɣi didi la sɔ gbɔ wu ga si wodo le gɔmedzedzea me. Asitsahabɔbɔwo ate ŋu ana woƒe adzɔnu ƒe ŋkɔ nanyo ɖe edzi eye wòadze nuƒlela siwo tsia dzi ɖe nutome ŋu, si ana asisiwo nawɔ nuteƒe na wo wu eye woƒe lɔlɔ̃nu nanyo ɖe edzi.
Numekuku kple ŋgɔyiyi ƒe agbagbadzedze siwo le edzi yim la ku ɖe PLA ƒe agbalẽviwo ƒe nɔnɔmewo kple woƒe dɔwɔwɔ dodo ɖe ŋgɔ ŋu. Nu yeye siwo wowɔ le nuwo ŋuti dzɔdzɔmeŋutinunya kple wo ŋudɔwɔwɔ ƒe mɔnuwo me do ŋugbe be yewoana nusiwo wotu ɖe PLA dzi ƒe anyinɔnɔ tegbee kple wo zazã nanyo ɖe edzi wu.

Le nyataƒoƒo me la, PLA agbalẽ siwo gblẽna le nugbagbewo ŋu la tsi tre ɖi na kpɔɖeŋu ƒe tɔtrɔ le kaɖinuwo ƒe xexeame. Woƒe wɔwɔme si me gblẽa nu le nutome ŋu o, alesi woate ŋu azã wo le mɔ vovovowo nu, kple woƒe atsyɔ̃ɖoɖo ƒe nu lédzinamewo na wonye nuwɔna siwo li tegbee ƒe dzogoedzikpe le agbalẽvi wɔwɔ me. To agbalẽvi yeye siawo xɔxɔ me la, menye ɖeko asitsalawo kpea asi ɖe nutome takpɔkpɔ ŋu ko o, ke wodoa woƒe adzɔnu ƒe ŋkɔ ɖe dzi le nuƒlela siwo tsɔa dzitsinya ɖɔa li wo nɔewo hã ŋkume.
