FEATURED PROJECT – INTELLIGENCE AND BUSINESS ANALYSIS FOR ADDITIVE MANUFACTURING
Client: MIMETE (FOMAS GROUP)
Scope of work: Market Analysis and business plan, selection of more suitable production technology.
A new industrial initiative has been launched to manufacture metallic powders by gas atomization.
Contract value : xxx k€
Duration: 3 months
New opportunities regarding the alloy design, process and product development, participation in funded projects (Domestic an EU)
Innovation & Business
Strategy
Design for AM
Development of the metal alloy
The alloy design and the alloys development is necessary to define the best chemical
composition for AM processes.
This will lead to a new proprietary alloy, very suitable for AM technologies.
This alloy design and development will be focused on aluminum alloys.
The commercial Al alloys actually available for AM processes have limited mechanical
properties as shown in the Figure below (Metal AM - Metal powders – the raw materials).
The market needs an increase of mechanical behavior for high demanding applications
and this goal can be achieved by a proper new alloy design.

Integrity Assessment
Design Options for
Transporting Gas from Remote Areas
Overall gas demand pushing for long distance gas transmission pipelines:
from Mid-Asia to East China-Korea and to Europe
in North America from Alaska to Canadian-USA market
Higher steel grade
(same WT)
Higher internal
pressure
Higher flow rate
Conveying large gas quantity by high diameter (≥36”) and HP (>100 bar)
Avoiding excessive increase of WT by using HSS pipes (X80 and beyond)
Integrity Management
