Volvos nästa steg inom additiv tillverkning (Swedish)
Abstract [sv]

Ett av teknikens mest växande områden idag är additiv tillverkning med ett stort applikationsområde som bara växer. Additiv tillverkning är när man tillverkar komponenter genom att lägga till material istället för att avlägsna material för att tillverka en komponent. I samband med att tekniken utvecklas har additiv tillverkning blivit mer och mer vanligt inom industrin där dess applikationer kan spara företagen en stor summa pengar. Ett område där additiv tillverkning kan visas användbart är i produktionen på Volvo GTO, Umeå som är Volvos ledande tillverkare av lastbilshyttar. För att undersöka om additiv tillverkning kan sänka tillverkningskostnaden, öka kvalitén på produkten eller minska leveranstiden på fabriken så har utredaren genom att ha möten och diskussioner med anställda på fabriken försökt att hitta case där den additiva tekniken kan appliceras. Sex case hittades och undersöktes. Casen handlade bland annat om munstycken i tätningslinan, vakumformningsmallar till snickeriet och fördelningsbrickor på målerirobotar. Casen utreddes genom undersökning och tester för att se vilken additiv teknik som passade bäst för just det fallet. När alla case hade undersökts klart så skapades det en investeringsprioritering för att skapa en plan för hur fabriken ska fortsätta sin satsning på den additiva tekniken. Ordningen på listan baseras på vad utredaren tyckte var viktigast och genomförbart. Ordningen blev: FFF-skrivare utan låst materialsystem, SLA-skrivare och sist hamnade MJF-skrivare. Det bedömdes även att fabriken kan spara in 423 384 SEK om året redan nu genom att utnyttja andra additiva tekniker än den som redan finns på plats i fabriken.

Abstract [en]

One of the fastest growing areas in the manufacturing industry today is additive manufacturing with a large application area that is only getting bigger. Additive manufacturing is when material is added instead of removed in order to produce a part. In connection with the technology being developed, additive manufacturing has become more and more common in the industry where its applications can save companies a large amount of money. An area where additive manufacturing can be shown to be useful is in the production at Volvo GTO, Umeå which is Volvo's leading manufacturer of truck cabins. To investigate whether additive manufacturing can reduce the manufacturing cost, increase the quality of the product or reduce the delivery time at the factory, the investigator has researched what possible cases related to additive manufacturing there is by having meetings and discussions with employees at the factory and finding where the additive technology could be applied. Six cases were found that were investigated. The cases included, among other things, nozzles in the sealing line, vacuum forming templates for the carpentry department and paint distributors on painting robots. The cases were investigated by examining and testing to see which additive technology is best suited for that particular case. When all cases had been investigated thoroughly, an investment priority list was created to create a plan for how the factory should continue its investment in the additive technology. The order on the list is based on what the investigator thought was most important and feasible. The sequence became: FFF printer without locked material system, SLA printer and a MJF printer. It was also found that the factory can save 423 384 SEK a year already by utilizing other additive methods than the one already in place in the factory.
