Ukadaulo watsopano wosindikiza wa 3D ukupangidwa mwachangu kwambiri kotero kuti ndikosavuta kuganiza zamtsogolo momwe mulibe chilichonse chomwe sichingasindikizidwe ndi 3D.
Kusiyanasiyana kwazinthu zomwe zilipo ndi chimodzi mwazolepheretsa kutengera kusindikiza kwa mafakitale a 3D.Kusindikiza kwa 3D kukulandiridwa mwachangu ndi opanga zinthu padziko lonse lapansi, komabe sikungathe kupikisana ndi njira zina zambiri zopangira potengera kusiyanasiyana kwazinthu.Mapulasitiki ambiri omwe amagwiritsidwa ntchito kwambiri m'mafakitale sakupezekabe kwa osindikiza a 3D, zomwe zimapangitsa kusindikiza kwa 3D kukhala kosayenera kwa mapulogalamu ambiri.
PTFE (polytetrafluoroethylene) ndi chinthu chothandiza kwambiri, chomwe chimagwiritsidwa ntchito pazinthu zambiri zatsiku ndi tsiku.Ndi hydrophobic kwambiri, kutanthauza kuti palibe madzi kapena zinthu zomwe zili ndi madzi zomwe zimapangitsa kuti zikhale zonyowa, choncho zimagwiritsidwa ntchito pazovala zakunja.Ilinso ndi imodzi mwama friction coefficients otsika kwambiri aliwonse olimba.Ndi malo okhawo omwe nalimata sangathe kumamatirapo.Katunduyu amapangitsa kuti ikhale yabwino kwa zokutira zopanda ndodo za bakeware.Mabakiteriya ndi tizilombo tina timakhalanso ndi nthawi yovuta kwambiri kumamatira kuzinthuzo, zomwe zimapangitsa kukhala njira yabwino kwambiri yogwiritsira ntchito chipatala zosiyanasiyana, monga ma catheters.
Ma fluoropolymers ena amagwiritsidwanso ntchito kwambiri m'mafakitale amafuta ndi gasi, mankhwala, magalimoto ndi ndege, ndipo ndizotheka kuti ukadaulo womwewo wa 3D wosindikiza ungagwiritsidwe ntchito kwa iwo.Kupambana uku kumapangitsa kuti 3D isindikize zida zatsopano, zomwe zingakhudze mafakitale ambiri.
Nthawi zambiri, magawo opangidwa kuchokera ku PTFE ndi ma fluoropolymers ena amapangidwa pogwiritsa ntchito njira zodula zachikhalidwe, zomwe nthawi zambiri zimapanga zinyalala zambiri.Zimakhalanso zovuta kupanga mapangidwe ovuta kwambiri.3D kusindikizaali ndi kuthekera kopereka zopanga zokhazikika komanso mitundu yosiyanasiyana yamitundu.Kupambanaku kukutsegula kale njira ya ntchito zosatheka kale.
Ma polima opangidwa ndi fluorinated, aka fluoropolymers, sangakhale okongola ngati diamondi, koma ndi zinthu zofunika kwambiri pakupanga zambiri.Mapulasitiki opangidwa ndi fluorocarbon amasiyanitsidwa ndi kukhazikika kwawo kwamphamvu komanso kukana mankhwala owopsa komanso kutentha kwambiri.Zogwiritsidwa ntchito m'chilichonse kuyambira zamlengalenga ndi zodzitchinjiriza mpaka zophikira zopanda ndodo, ma fluoropolymers ali paliponse - kupatula mu osindikiza a 3D.
Izi zitha kusintha posachedwa, pomwe kampani yopanga zinthu za 3M yapereka chiphaso cha mtundu watsopano waukadaulo wosindikizira wa 3D womwe ungalole kupanga zowonjezera za ma polima okhala ndi fluorinated mokwanira.Ukadaulowu utanthauza kuti zomanga zovuta zitha kupangidwa mwachangu komanso zotsika mtengo, pomwe magawo omwewo nthawi zambiri amakhala okwera mtengo kwambiri kupanga ndi njira zina zopangira.
Ngakhale pali mitundu yambiri ya ma polima a fluorinated, mwina yomwe ingapindule kwambiri ndi kusindikiza kwa 3D ndi polytetrafluoroethylene kapena PTFE, yomwe imadziwika kuti polima.PTFE, yomwe nthawi zambiri imagwiritsidwa ntchito ngati kusindikiza ndi kukaniza, imapanga zinyalala zambiri popanga.Kusindikiza kwa 3D - komwe 3M idzakhala yoyamba kuchita - idzachepetsa kwambiri zinyalalazo.Kuphatikiza apo, makampani omwe amapezerapo mwayi pa ntchitoyi azitha kupanga zovuta, zopanga ma polima ambiri pachidutswa chimodzi m'malo mopanga ndikusonkhanitsa magawo angapo.
