Nayiloni ndi gulu lodziwika bwino la mapulasitiki omwe akhalapo kuyambira 1930s. Ndi ma polima a polyamide omwe nthawi zambiri amagwiritsidwa ntchito m'njira zingapo zopangira pulasitiki zamakanema apulasitiki, zokutira zitsulo ndi machubu amafuta ndi gasi - mwa zina. Nthawi zambiri, ma nayiloni ndi otchuka kwambiri pazowonjezera chifukwa cha kutha kwake, monga momwe zafotokozedwera mu lipoti lapachaka la 2017 State of 3D Printing. Zomwe zimagwiritsidwa ntchito kwambiri ndi SLS ndiPolyamide 12 (PA 12), yomwe imadziwikanso kuti Nayiloni 12 PA 12 (yomwe imadziwikanso kuti Nylon 12) ndi pulasitiki yabwino yogwiritsidwa ntchito nthawi zonse yokhala ndi zowonjezera zambiri ndipo imadziwika chifukwa cha kulimba kwake, kulimba kwake, kulimba kwamphamvu komanso kutha kusinthasintha popanda kusweka. PA 12 yakhala ikugwiritsidwa ntchito ndi opangira jakisoni chifukwa cha makinawa. Ndipo posachedwa, PA 12 yatengedwa ngati chosindikizira wamba cha 3D popanga magawo ogwira ntchito ndi ma prototypes.
Nayiloni 12ndi polima nayiloni. Amapangidwa kuchokera ku ω-amino lauric acid kapena laurolactam monomers kuti iliyonse ili ndi ma carbon 12, motero dzina lakuti "Nayiloni 12". Makhalidwe ake ali pakati pa ma nayiloni amfupi a aliphatic (monga PA 6 ndi PA 66) ndi ma polyolefins. PA 12 ndi nayiloni yayitali ya kaboni. Mayamwidwe amadzi otsika ndi kachulukidwe, 1.01 g/mL, amachokera ku utali wake wautali wa hydrocarbon chain, womwe umapangitsanso kukhazikika kwake komanso mawonekedwe ngati parafini. Katundu wa Nylon 12 amaphatikiza mawonekedwe otsika kwambiri amayamwa madzi a ma polyamides onse, zomwe zikutanthauza kuti magawo aliwonse opangidwa kuchokera ku PA 12 ayenera kukhala okhazikika m'malo achinyezi.
Kuphatikiza apo, polyamide 12 yokhala ndi kukana bwino kwamankhwala, ndikuchepetsa kukhudzika kwa kupsinjika kwapang'onopang'ono. Pazigawo zouma zouma, chitsulo chotsetsereka chachitsulo, POM, PBT ndi zinthu zina ndizotsika, zokhala ndi kukana kwabwino kwambiri, kukhazikika, kulimba kwambiri, komanso kukana kwamphamvu. Pakadali pano, PA 12 ndi insulator yabwino yamagetsi ndipo, monga ma polyamides ena, samakhudza kutsekemera ndi chinyezi. Kupatula apo, PA 12 ulusi wamagalasi wautali wolimbikitsidwa ndi thermoplastic uli ndi phokoso labwino komanso kugwedera kwamadzi.
PA 12lakhala likugwiritsidwa ntchito ngati pulasitiki mu makampani magalimoto kwa zaka zambiri: zitsanzo za mapaipi multilayer opangidwa PA 12 monga mizere mafuta, mizere pneumatic ananyema, mizere hayidiroliki, dongosolo mpweya intake, dongosolo mpweya mphamvu, dongosolo hayidiroliki, zamagetsi zamagetsi ndi kuyatsa, kuzirala ndi mpweya dongosolo mpweya, dongosolo mafuta, dongosolo mphamvu ndi galimoto magalimoto osawerengeka padziko lonse lapansi opanga magalimoto. Kukaniza kwake kwamankhwala komanso mawonekedwe apamwamba amakina zimapangitsa PA 12 kukhala chinthu choyenera kulumikizana ndi media chomwe chili ndi ma hydrocarbon.
Ngati mukufuna kudziwa zambiri ndipo mukufuna kupanga chosindikizira cha 3d, chonde lemberaniJSADD 3D Manufacturernthawi iliyonse.
