Billigare, b\u00e4ttre kvalitet, enklare och mer flexibelt.<\/strong><\/p>\n

SJ ser stora f\u00f6rdelar och utvecklingsm\u00f6jligheter av bolagets p\u00e5b\u00f6rjade tillverkning av reservdelar med hj\u00e4lp av modern 3D-teknik.<\/p>\n

\u2013 Vi har kommit s\u00e5 l\u00e5ngt nu att vi faktiskt b\u00f6rjat serietillverka delar, och att det blir billigare \u00e4n att tillverka delarna med traditionell teknik, s\u00e4ger Anders Gustafsson, chef f\u00f6r stora projekt p\u00e5 SJ:s division Fordon, till TT.<\/p>\n

Han s\u00e4ger att SJ gjorde f\u00f6rstudier om tillverkning med 3D-skrivare 2017 och kom ig\u00e5ng p\u00e5 allvar i fjol. Nu har en best\u00e4llning p\u00e5 200 serietillverkade delar lagts.<\/p>\n

Tekniken f\u00f6renklar produktionen, och enligt Gustafsson blir det billigare f\u00f6r b\u00e5de SJ och samh\u00e4llet i stort.<\/p>\n

\u2013 Jag skulle s\u00e4ga att de st\u00f6rsta besparingarna i nul\u00e4get \u00e4r att vi f\u00e5r tag i delarna \u00f6ver huvudtaget och att vi p\u00e5 det s\u00e4ttet f\u00e5r ut t\u00e5gen i trafik och kan k\u00f6ra resen\u00e4rerna.<\/p>\n

Undvika piratkopiering
\nDe f\u00f6rsta 3D-printade reservdelarna hos SJ \u00e4r en vidareutvecklad h\u00e5llare f\u00f6r toalettrullar i plast till SJ 3000-t\u00e5gen, toalettl\u00e5s i metall till personvagnar samt skyddsk\u00e5por till eluttag och ventilationslock.<\/p>\n

Men ett m\u00f6jligt problem i sammanhanget \u00e4r att tillverkare av originaldelarna kan ha synpunkter p\u00e5 licenser och piratkopiering.<\/p>\n

\u2013 Det \u00e4r d\u00e4rf\u00f6r vi nu har koncentrerat oss s\u00e5dana reservdelar d\u00e4r det inte l\u00e4ngre finns n\u00e5gra r\u00e4ttigheter och ingen som vill eller kan s\u00e4lja delen. Det \u00e4r ofta lite \u00e4ldre delar, s\u00e4ger Gustafsson.<\/p>\n

Enligt honom kommer upphandlingar av t\u00e5g fram\u00f6ver ocks\u00e5 inneh\u00e5lla ritningsr\u00e4ttigheter till olika delar.<\/p>\n

”Mera snabbfotade”
\nGustafsson s\u00e4ger att 3D-tekniken ocks\u00e5 g\u00f6r att reservdelar mer kan tillverkas n\u00e4r de verkligen beh\u00f6vs av de stora tillverkare SJ samarbetar med i st\u00e4llet f\u00f6r att ligga lagerf\u00f6rda inf\u00f6r ett eventuellt behov. Dessutom kan materialen f\u00f6rb\u00e4ttras kvalitativt, leveranstiderna f\u00f6rkortas och administrationen effektiviseras, s\u00e4ger Gustafsson.<\/p>\n

\u2013 Vi blir v\u00e4ldigt mycket mera snabbfotade.<\/p>\n

Hittills har SJ l\u00e5tit printa reservdelar som inte p\u00e5verkar t\u00e5gens s\u00e4kerhet. Men nu \u00e4r bolaget p\u00e5 v\u00e4g att g\u00e5 l\u00e4ngre och \u00e4ven 3D-tillverka s\u00e4kerhetsk\u00e4nsliga delar. Den f\u00f6rsta delen som ber\u00f6rs har med t\u00e5gens hjulaxlar att g\u00f6ra och den har b\u00f6rjat genomg\u00e5 den process som ska leda fram till ett s\u00e4kerhetsgodk\u00e4nnande.<\/p>\n

\u2013 Under n\u00e4sta \u00e5r kommer vi sannolikt att kunna montera det f\u00f6rsta exemplaret av den delen, s\u00e4ger Gustafsson.<\/p>\n
