TPU yo gucapa mu buryo bwa 3D

TPU (Polyurethane ya Thermoplastic) ni elastomer ya thermoplastic (TPE) ikoreshwa cyane mu gucapa mu buryo bwa 3D, ihuza uburyo bworoshye bwo gutunganya ibintu nk'ibya rubber hamwe n'uburyo bworoshye bwo gutunganya ibintu. Ni copolymer y'igice gikomeye (imbaraga) n'igice cyoroshye (ubukonje), iboneka nk'umunyururu wa 1.75mm/2.85mm FDM cyangwa ifu ya SLS ku bice byoroshye kandi biramba.

Imitungo y'ingenzi n'ibyiza by'ingenzi

• Gukomera nk'umukara: Ubukomere bw'inkombe 65A–60D; buramba kugeza kuri 500% mu gihe cyo kuruhuka nta gucika.
• Kuramba cyane: Irashwanyagurika cyane, iracika, irarwanya amavuta n'imiti; ihangana no kunama kenshi.
• Gufata Ihungabana: Bigabanya umuvuduko n'ingaruka, bikaba byiza cyane ku bice birinda kandi bifasha mu kurinda.
• Ubushyuhe bwagutse: Ikora neza kuva kuri -20°C kugeza kuri 60°C; irwanya imirasire ya UV no gusaza.
• Uburyo bworoshye bwo guhindura: Hindura ubukana (60A–95A) n'ubucucike bw'ibice byinjiramo (10–100%) kugira ngo bibe byoroshye/bikomeye.
• Gufata neza urwego: Bicapa neza kandi bifite imigozi ikomeye hagati y’urwego, nta gutandukana kw’imiterere.

Porogaramu zisanzwe zo gucapa mu buryo bwa 3D

• Ibicuruzwa bikoreshwa n'abaguzi: Amasakoshi ya terefone, imikandara y'isaha, inkweto zo ku rukenyerero, n'ibikoresho byo gufataho ibikoresho.
  Ibice by'inganda: Ibifunga, gasket, ibikoresho byo gutigita, n'ibice bidatemba.
• Ubuvuzi: Insoles zo mu nda z'amenyo, imitako y'inyongera, n'imitako y'ibikoresho by'ubuvuzi.
  Siporo no hanze: Ibikoresho byo kwirinda, ingofero, n'ibikoresho byoroshye gukoresha.
• Imodoka: Ifuru z'inzugi, imitako yo mu bwoko bwa bumper, n'imitako yoroshye imbere.

Ibipimo bisanzwe byo gucapa (FDM)

• Ubushyuhe bw'akazuzu: 220–250°C
• Ubushyuhe bwo ku buriri: 40–60°C
• Umuvuduko wo gucapa: 20–30 mm/s (gahoro kugira ngo woroshye)
• Ubucucike bw'ibicuruzwa: 10–20% (byoroshye) / 50–100% (bikomeye)
