Styles also touched upon the more general issues with outsourcing: “If a company is making parts for themselves, such as GE printing advanced fuel pump nozzles for their engines, then they can control their proprietary design as well as directly monitor the quality of the results – important considerations for such a sophisticated part performing a critical function.”Â. CFM International’s 3D-printed fuel nozzle. Privacy Policy. CH 1 Multiple choice. ), “When does it make sense to add 3D metal printing to a conventional machine shop production environment?  That depends on a lot of caveats, of course, but for me the choice can be reduced to a few essential considerations.”, “First, you must have a skilled and experienced technologist or engineer on staff to run the metal printing process.  This is not subtractive machining and it requires a completely different skill set.  Without that the effort is doomed to be a disappointment at best.”Â, “Secondly,” Styles continued, “you must remember that there are substantial upfront costs that can possibly justify the investment only if there is sufficient volume of parts or a high margin built into the finished product.”. “Third, AM can win if it is able, through part redesign, to enhance the performance of the component or components. Beuth explained it this way: “We break it down into three factors that can lead to adoption of AM over conventional processing. Below is an approximate number of multiple choice questions on the exams. Home. The process is essentially a form of automated build-up welding. It is just getting started.”. ADDITIVE MANUFACTURING. It should be noted that respondents could select all the barriers that applied to them, which explains why the percent totals of all choices add up to more than 100. ), A selection of metal additive parts. But with additive processes, you’re forming the internal microstructure as you go. If you happened to work in manufacturing, you might push for adopting computer numerical control (CNC). DED naturally lends itself to hybrid setups. So many, it seems, that Canadian manufacturers are still skeptical of its value. Home. 9. On the whole, the number of manufacturers who believe that 3D printing will become a mass production technology within the next three to five years has increased by four percent.
