AddUp Start

AddUp Start will assist you in preparing all the upstream stages of the industrialization of your part by taking into account all the constraints of your industrial sector.

To support you in operating metal 3D printing industrially, AddUp offers a broad range of services from the expression of your needs to assistance in implementing a production run.

For certain industrial sectors, AddUp Start is organized in Hubs using the specific expertise of key partners to integrate 3D printing into different industrial sectors.


As each industry as its own its design specifics, it is a natural fit to have a Hub per industry.

AddUp has therefore chosen to pool together in each Hub:

  • Experts from each industry to design or redesign customers’ parts by integrating their design specificities,
  • Experts from metal additive manufacturing in order to exploit all the possibilities of this new technology.

We can either completely redesign the part working hand in hand with your technical team or advise your design team before working together in the redesign of the part.


The design of parts in 3D printing often makes it possible to integrate in one single part more functions than were initially designed. Our experts are used to thinking like this and will support you in this paradigm change, whilst taking into account your specificities and constraints.


The topological optimization of parts enables the design of lighter parts by only using the material where necessary and ensuring that it maintains its resistance to efforts and stress and is compliant with the initial specifications.
The operation can be carried out on the basis of mathematical models by applying them to traditional parts.
Our Hub experts with their in-depth knowledge of your industry will propose to you topological developments which are compatible with your business landscape.


Operational optimization is the taking into account of all the design rules specific to your industry in order to design parts and new functionalities which are perfectly tailored to your needs.
Whether it is from an idea or based on a functional objective, our Hub experts have all the in-depth knowledge of your industry to support you and help you create a new cutting-edge design integrating all the possibilities of additive manufacturing.
All the design constraints and rules inherent to additive manufacturing, on the one hand, and the control, processing and fabrication re-work needs, on the other hand, are taken into account in the redesign proposals.


During this stage, a team of experts will validate via calcul simulation all the key elements which need to be taken into account in your specifications whilst checking the feasibility of additive manufacturing.



The choice of materials to be adapted to the required functions is a process which naturally takes into account your constraints but also those of additive manufacturing. It is sometimes pertinent to question the historical choice of materials, as they may have previously been selected for industrialization requirements on conventional processes (foundry work, machining, forging, etc.).
AddUp does not produce powder, and as our machines are open architecture and compatible with all the powders found on the market, our experts will help you in full transparency and neutrality to choose the best powder adapted to your needs.

The required finishing, precision and roughness will be decisive in the choice of the size and the grade of the powder.

Recipes and machine adjustments are already available in the following materials:

  • Stainless steels
    316L (1.4404)
  • Maraging steels
    18Ni300 (1.2709)
  • Nickel alloys
    Inconel™ 718 et 625
  • Titanium alloys
    Ti6A4V / Ti40
  • Aluminium alloys

Is your material not on the list?
Please contact us to assess the development deadline and the machine adjustments and tests.


Your industry has specific needs and you wish:

  • To study additive manufacturing for a new material to be developed for very specific needs,
  • Assess a material which currently does not have an industrial application because it is difficult to implement by conventional methods

Contact us so that we can assess together all these developments possibilities.


Our experts will support you by:

  • Advising you on the materials which are best adapted to your applications and your industrial sector’s constraints.
  • Help you characterize your material in order to obtain the product-process certification which is indispensable in succeeding your industrialization.
  • Enable you to obtain the required material characteristics thanks to fine-tuning:
  • The machine adjustment parameters (temperature, rare gas)
  • The parameters and proprieties during the powder preparation
  • The strategies for positioning the parts on the plate
  • The material melting strategies (speed, paths)
  • etc.

Depending on the targeted characteristics, post-processing of the parts after printing may be necessary.


Additive technologies

It is important, in accordance with your industrial goal, to choose an additive technology which is best adapted to your project.

Via more than 10 years of experience in the use of additive manufacturing by Michelin, AddUp’s specialized Hubs will advise you on which printing technology is best adapted to your constraints and your needs.

The technologies


AddUp implements direct metal laser melting on an industrial scale. With this technology, low granulometry powder and a small-diameter laser can be used to make parts that combine precision, surface quality, material integrity, and internal stress levels.

Example of the level of precision obtained on small-scale maraging steel parts: +/- 35 µm


AddUp and its specialized Hubs, along with the know-how it has gained from Michelin’s unique experience in the industrialization of additive manufacturing, will assist you in choosing the production method which is best adapted to your project: the choice between a single machine or a partially or entirely automated production line, will depend on your application (material, form and size of the part), on the targeted line speed, the required accuracy and characteristics.


The product-process combination is key when qualifying your part and certifying the production methods. The Hub experts corresponding to your industrial sector have in-depth knowledge of the constraints and rules linked to your industry: they will know how to support you during every step of certification.


The Hub experts will study the economic profitability of your parts, in full knowledge that when assessing the production cost of a part, a lot of elements need to be taken into account:

  • The required final quality and finishing with or without post-processing, depending on the applications
  • The choice of material (type, size, grade, quality) which is best adapted to the situation
  • The shape of the parts and positioning on the plate entailing a variable optimization of the number of supports to be produced
  • The characteristics of the machine or the production line
  • The lasing strategies chosen to obtain the parts’ characteristics.
  • etc.


In the framework of a certification of a part, AddUp will advise you on how to manage and control the additive manufacturing process.


POC (Proof Of Concept) or “Demonstrator” is one of AddUp Start’s key deliverables in demonstrating the potential of additive manufacturing and its feasibility.
POC can also be used to validate adjustment parameters and the selected technical-economic choice.

The printing of the POC is also a key stage in obtaining the product-process certification which is an indispensable element in the success of your industrialization.

The Hub experts who have in-depth knowledge of your industry will manage all the key parameters for a high-quality production:

  • Optimization of the supports
  • Positioning & orientation of parts on the plate
  • Layering and lasing strategy
  • Predictive simulation, …

The AddUp production lines


  • 5 independent units with proprietary additive manufacturing machines,
  • A room with post-processing / finishing equipment
  • A measurement room for qualifying parts

AddUp’s machine fleet will change over the coming years, to support its customers specific execution needs.

Production lines inside the HUBs

Furthermore, when the Hubs are implemented, production lines will be installed in the HUB premises in order to produce POCs in the specific conditions of the industry in question.

We are building a production line with a much greater capacity and which will be up and running in AddUp’s premises in 2019 in order to meet the strong growth in POC production requests.

In order to promote the use of additive manufacturing, AddUp gives access to a cell to SMBs and local players, while respecting the customer's confidentiality. This initiative is supported by the Auvergne-Rhône-Alpes region.
