Online acquisition firm for marine machine ShipParts.com has struck a research partnership deal with Nanyang Polytechnic (NYP) of Singapore and the American Bureau of Shipping (ABS). The deal seeks to determine measures for the approval of metallic pieces manufactured by NYP’s Additive Manufacturing Innovation Centre (AMIC) for marine utilizations.
The SGD$350,000 scheme, partially financed by the National Additive Manufacturing Innovation Cluster (NAMIC), will approve the 3D printed metal pieces of an end-user segment utilizing a Selective Laser Melting additive manufacturing device. The SLM technology has the capacity to print multiple pieces in a diversity of as well as stainless steel SS316L, which is universally used across the sector due to the destructive nature of the marine setting.
In the initial stage of the 10-month project, starting in April 2020, the research teams will create metal part printing processes and perform tensile, substance, and microstructure examinations of the printing channels against ABS regulations and measures guiding weld and material energy.
Stage two will consist of the additive manufacturing of a pump impeller metal piece and examine the performance of the piece in a regular machine. The project is anticipated to finish in January next year.
Chief growth officer at ShipParts.com, Roy Yap said this: “A key aspect of the project is to optimize the parameters for the printed part that post-machining is minimized and it can be used ideally ‘hot off the oven’. The qualification will form the bedrock for future certification of critical components for marine use.”
NYP’s Additive Manufacturing Innovation Centre (AMiC) will create the metal printing examination plan, systems and methods, facilitate experimentation and review. ShipParts.com will offer the design guidelines for pieces made by 3D metal printing authorized via its consortium of production associates On the other hand ABS will create new examination and approval levels and review the production process.
“We are excited to be part of this project as it has the potential to place Singapore at the forefront of the maritime industry’s 3D printing hub. With NYP’s vast expertise in Additive Manufacturing, we are well-placed to ensure that the quality and reliability of the parts produced are consistent and meet qualification standards,” says Centre director of NYP’s AMiC, Desmond Tan.
“3D printing of metallic components has significant potential for maritime and offshore industry applications and ABS is leading this field. ABS has already published Guidance Notes on Additive Manufacturing to introduce a qualification scheme that defines processes with sufficient clarity to achieve consistent, repeatable results. The outcome of this research will be a comprehensive certification process,” says business development manager at ABS Singapore, Soh Mei Yan.
The associates assume that the metallic AM will transform the marine and offshore industry, giving space for dispersed production and, decreased logistics, therefore contributing to international attempts to decarbonize.
“Current investment and take-up will drive cost downwards with a technology leap expected by 2022 for larger parts. There are now more material choices and more accurate 3D printing machines capable of manufacturing components in a more cost-effective way,” says Yap.
