Cas de réussite de la mise en œuvre de la technologie SLS avec Sinterit Lisa dans le bureau de service

Depuis son lancement sur le marché, l'imprimante Sinterit Lisa a été une révolution. Il s'agit de la première imprimante SLS abordable au format de bureau. Sa haute qualité, sa facilité d'utilisation, son prix bas et sa taille compacte en ont fait une niche dans des secteurs où, jusqu'à récemment, il était considéré comme irréalisable d'introduire cette technologie.

L'un de ces secteurs est le service bureau , des entreprises qui fournissent des services à d'autres entreprises et qui peuvent être à la fois de conception, d'ingénierie ou de conseil. L'une des particularités de ce type de commerces est qu'ils sont généralement situés dans des bureaux. C'est pourquoi il était traditionnellement impossible de mettre en place un équipement d'impression 3D SLS dans ce type d'entreprise, car elle ne disposait pas de l'espace nécessaire ou d'autres exigences telles que des installations de gaz ou des alimentations électriques de forte puissance.

Cela a fait que de nombreuses entreprises telles que les studios de design, les bureaux d'études ou les petites entreprises de prototypage ont historiquement dû recourir à l'externalisation de cette technologie, avec les coûts que cela implique.

Un de ces exemples sont les petites entreprises de prototypage, généralement limitées à l'utilisation de FDM ou SLA. Nous avons interviewé le directeur technique de l'un d'entre eux et il nous a parlé de son expérience en ajoutant la technologie SLS à son portefeuille de services en acquérant une imprimante 3D SLS Sinterit Lisa.

F2P : Bonjour Eloy. Pourriez-vous nous parler un peu de votre parcours professionnel et de votre expérience dans le monde de l'impression 3D et du prototypage ?

E.B. : Pendant 11 ans, j'ai été le directeur technique d'Eceleni, une entreprise dédiée à la fabrication de prototypes et de petites séries, mais mes origines viennent du design industriel, tant dans la conception de produits que dans la conception de moules. La première fois que j'ai vu une stéréolithographie, c'était il y a plus de 20 ans, alors que je travaillais comme dessinateur dans un atelier de moulage. La vérité est que le client qui l'a apporté ne nous a pas quitté ni ne l'a touché. À l'époque, personne ne parlait d'impression 3D, juste de stéréolithographie.

F2P: At Eceleni you work both subtractive manufacturing (CNC machining) and additive manufacturing (3D printing) and formative (fast silicone molds). What do you think 3D printing can provide over other technologies?

E.B.: In most cases, 3D printing makes it possible to manufacture geometries that could not otherwise be manufactured (for example Lattices or Voronoi) and immediacy when manufacturing short series or prototypes. Although it is true that in relatively large pieces, both the term and the cost are better for machining, and depending on the quantity, training techniques are still the best option.

F2P: Currently you offer 3D printing through Polyjet, FDM and SLS, what does the latter give you compared to the other two?

E.B.: SLS technology has a better surface finish than FDM technology and superior mechanical resistance than PolyJet. For example, the elastomers manufactured by SLS have a superior resistance to breakage than Polyjet's flexible resins.

F2P: Among your equipment you have the Sinterit Lisa 3D SLS printer, could you tell us why you have chosen this SLS 3D printer and not another model that is available on the market?

E.B.: Compared to other options in SLS, it is the best value for money. If instead of being an additive manufacturing service bureau, it were for our own use, we would also have one.

F2P: Sinterit Lisa stands out for being the first SLS 3D printer in desktop format, has this influenced your decision to purchase it? Has this format been of any advantage to you compared to classic industrial formats?

E.B.: Although it does not have the largest bucket on the market, that for many manufactures is a point in favor, since the minimum amount of material is wasted, and the cooling time is much shorter than large machines, so the piece in a shorter time. Depending on the type of part to be manufactured in SLS, we manufacture them without hesitation in the Lisa.

F2P: Could you tell us what your first contact with Sinterit Lisa was like? Has the installation been simple or have you had any problems?

E.B.: Sinterit Lisa comes ready to be used. It is a robust machine, and ready to go to manufacture once unpacked.

F2P: Traditionally, 3D SLS printing has been considered a complex technology, both at the user and implementation level, compared to other more common ones such as FDM. After using Sinterit Lisa, do you consider this to be true? Compared to an FDM printer, do you find using Lisa much more complicated?

E.B.: I suppose they are considered more complex because SLS 3D printers have always been large industrial machines, which, not being as visual as FDM, are understood to be more complex, but in the case of the Sinterit Lisa printer, nothing is further from reality. .

F2P: Sinterit Lisa comes with her own slicing software, Sinterit Studio. How has your experience been with this software?

E.B.: Sinterit Studio is very, very, very easy to use. Even more so than FDM slicers, as you don't have to consider where to put the brackets.

F2P: How difficult would you say it is compared to other printers you have worked with?

E.B.: The Sinterit Lisa is a very grateful machine:it does not have complex mechanics and you do not have to worry about the material jamming. The great secret to having good impressions on the Sinterit Lisa is to put the piece in the most irregular position possible, even if it takes a little longer.

F2P: One of the strengths of Sinterit products is their conception as Plug-and-Play equipment. Would you consider this true? Since you received the printer, has it been difficult for you to adopt the workflow and start producing with it?

E.B.: Sure enough, it was plug and play. Being a closed machine, you only have to load the material and print, without further complications. In addition, thanks to the camera installed in the printer, you can verify its operation from the workplace.

F2P: After this time with Sinterit Lisa, what would you highlight about her? Do you consider it to have been a successful acquisition?

E.B.: Very successful! We are currently working a lot with the Flexa Gray material, which allows us to make TPU pieces with different hardnesses. It often happens that when a client sees the parts in PA12 in dark gray, she asks if they have been made with the MFJ. It is the same material, and the same color, although with better mechanical properties.

Being able to implement 3D SLS printing equipment in the service bureaus ' own facilities can mean a very significant increase in value for this type of business. Leaving the outsourcing of 3D SLS printing services means, in addition to significant cost savings in the short and medium term, time savings that increase responsiveness to the customer.

Without a doubt, both Lisa and Lisa Pro have become a benchmark in the world of 3D printing, which has led more and more offices and service bureaus to opt for this technology with satisfactory results.
