Additive Manufacturing is a challenge shared by all heat exchangers , and for applications suited to AM where compactness is critical , this is a bigger issue . Additively manufactured heat exchanger modules are following similar paths , and therefore have design and manufacturing precedents to follow : incorporating one or more AM cores in traditionally manufactured casings following similar linking strategies , or leverage direct joining of modular elements that are a single AM part . Comprehensive data on best practice and the effects of welding AM materials is not yet widespread .
Evolving certification and standards The AM process flow including the system / platform , process and material need to be qualified to a certain level to produce certified parts that meet standards , design specifications and end use performance targets . It is clear that qualification and certification are two topics that are critical for increasing the adoption of AM heat exchangers , and international standards are emerging for the AM industry . A growing number of specific parts , processes and facilities are being certified for high value applications , especially in aerospace . There are many other product specific standards under development by various bodies such as ISO , ASME and ASTM that could be applied more broadly across other industries . For example , the National
Aerospace and Defense Contractors Accreditation Program ( NADCAP ) now includes a certifiable standard ( AC7110 / 14 ) specifically for laser and electron beam powder bed fusion . As new applications are developed in the energy sector through research and commercial endeavor , additively manufactured heat exchangers will undoubtably find a growing niche in the energy market where compact , high value heat transfer efficiencies are required .
