Overview: 

​

The M2i2 research team has actively participated in the Additive Manufacturing Benchmarks of 2018 and 2022 (AM-Bench 2018 and AM-Bench 2022). These challenges represent the first in a series of benchmark tests aimed at validating the predictability of computational methods for additive manufacturing (AM).

 

Experimental Focus: 

​

The experiments conducted during these benchmarks involved a range of measurements, including:

 

• Microstructure variations

• Residual stresses

• Part distortions

• 3D grain structures

• Melt-pool geometry of both AM builds and simple single track passes

​

In 2018, the AM-Bench organising committee received a total of 46 challenge submissions from 19 groups, comprising 9 from North America, 6 from Europe, and 4 from Asia. The 2022 AM-Bench organising committee saw a significant increase, receiving 138 benchmark challenge submissions from 19 groups worldwide. The geographical distribution of the submitting groups included 15 from North America, 1 from Europe, and 3 from Asia.

 

Awards and Recognition:

​

M2i2 has been awarded the following prizes in recognition of its outstanding contributions:

 

1. NIST AM-Bench Challenge 2022 – 1st Prize: For the submission titled “Modelling results predicting phase evolution during post-build heat treatments of IN718 test artefacts produced using laser powder bed fusion.”

2. NIST AM-Bench Challenge 2022 – 2nd Prize: For the submission titled “Modelling results predicting residual elastic strain components at select locations internal to an as-built IN718 bridge structure.”

3. NIST AM-Bench Challenge 2018 – 1st Prize: For the submission titled “Best modelling results predicting the phase evolution during residual stress annealing of an as-built IN625 bridge structure.”

 

These accolades highlight the M2i2 team's commitment to advancing the field of additive manufacturing through rigorous research and innovative modelling techniques.
