Arsyetimi pse natyra duhet t\u00eb p\u00ebrdoret si nj\u00eb model \u00ebsht\u00eb e qart\u00eb.

Zemra e but\u00eb artificiale u krijua nga silikoni duke p\u00ebrdorur nj\u00eb teknik\u00eb t\u00eb printimit 3D; ajo peshon 390 gram dhe ka nj\u00eb volum 679 cm3. \u201c\u00cbsht\u00eb nj\u00eb monobllok silikoni me struktur\u00eb komplekse t\u00eb brendshme\u201c<\/em>, shpjegon Cohrs.<\/span><\/p>\n
