Remanufacturing of Damaged Parts Using Selective Laser Melting Technology

Abstract

This paper presents the stages taken to remanufacture a damaged part, for which no documentation is available, using the SLM additive technologies. A damaged part is scanned using the COMET L3D scanner and the points cloud is used to redesign and reconstruct the part as a 3D CAD model. Using the generated 3D CAD model the build job for the SLM is created by designing and adding the construction supports, the material type and the type of hatching strategy for each slice. The slices are used by the SLM250HL equipment and the new metallic part is manufactured. The manufactured part was scanned with the same 3D scanner and the data from the original part was compared with the new reading. The results can be used to reconstruct more complex parts, to redesign the broken parts and to improve the manufacturing process.

Framework to Predict the Environmental Impact of Additive Manufacturing in the Life Cycle of a Commercial Vehicle

“…Next to these benefits, parts with built-in functions can be manufactured to reduce machining and joining operations. Although with limitations, parts can be remanufactured with powder bed fusion to extend its lifetime [7]. To use these benefits, recent investigations try to overcome the limitations that come with powder bed fusion such as material properties of metal alloys, low process speed, high power consumption, level of process control and high powder prices which leads to high production costs [3].…”

Kutatási és alkalmazási tapasztalatok az additív gyártásban

“…Ennek egyik oka, hogy ilyen módon szinte minden anyag feldolgozható. [3,5] Az additív gyártás nem csak a technológia területén jelent jelentős változást, hanem a termékfejlesztés folyamatában is. A CAD testmodellen keresztül soha nem látott szoros kapcsolat alakulhat ki a számítógépes modellezéssel kifejlesztett terv és a megvalósítás között.…”
