Additiv tillverkning för högre teknisk tillgänglighet i internationella insatsområden

Abstract [en]

In this paper the military utility of additive manufacturing of spare parts during international deployment is explored. We also analyze the effect that additive manufacturing has on technical availability.

International deployment can be tough for logistical reasons and this leads to a difficulty in supplying ground troops with spare parts. If the spare parts cannot be acquired in the deployment area these have to be shipped from central distribution centers or be ordered directly from the industries. Some spare parts are uncommon and not stored in distribution centers but only get manufactured on order. This type of production can lead to delivery times of up to 40-50 weeks. With additive manufacturing this process could be shortened to 4-10 weeks.

Conclusions that can be drawn is that additive manufacturing has military utility and can give a higher technical availability, given that a few technical difficulties are resolved. At this point there is a shortcoming in the number of qualified materials for printing spare parts for regular vehicles and this makes it difficult for the industry to approve of spare parts constructed with additive manufacturing. The winning in technical availability is directly linked to how difficult the deployment area is to reach for logistical units. Additive manufacturing has a higher positive effect in areas that are hard to reach.

Abstract [sv]

I denna uppsats undersöks den millitära nyttan med additiv tillverkning av reservdelar för markförband under internationell insats och hur detta kan påverka den tekniska tillgängligheten på systemen.

Internationella insatser kan kräva långa logistikkedjor vilket innebär att reservdelar som inte kan införskaffas i närområdet måste fraktas från en bakre underhållsnivå eller beställas direkt från leverantör. Vid vissa tillfällen med skador på system som kräver nyproduktion av reservdelar från tillverkare, kan det i dagsläget ta upp till 40-50 veckor. Med additiv tillverkning kan förloppet kortas ner betydligt och tillverkningstiden blir istället 4-10 veckor.

Slutsatser som kan dras är att additiv tillverkning har en militär nytta och kan ge en högre teknisk tillgänglighet, förutsatt att en del tekniska svårigheter klaras ut. I dagsläget finns det brister i mängden kvalificerade material för utskrifter till vanliga fordon vilket gör det svårt för industrin att godkänna reservdelarna som en ordinarie reparationsmetod i sina produkter. Vinsten i teknisk tillgänglighet är också kopplad till hur svårtillgängligt insatsområdet är. Desto svårtillgängligare området är desto större vinst medför additiv tillverkning.
