Sinterit Lisa의 SLS 기술 구현 성공 사례

Sinterit Lisa 프린터는 시장에 출시된 이후로 혁명을 일으켰습니다. 데스크탑 형식의 최초의 저렴한 SLS 프린터입니다. 고품질, 사용 용이성, 저렴한 가격 및 작은 크기로 인해 최근까지 이 기술을 도입하는 것이 불가능하다고 여겨졌던 분야에서 틈새 시장이 되었습니다.

이러한 부문 중 하나는 서비스 부서입니다. , 다른 회사에 서비스를 제공하고 디자인, 엔지니어링 또는 컨설팅이 될 수 있는 비즈니스. 이러한 유형의 비즈니스의 특징 중 하나는 일반적으로 사무실에 위치한다는 것입니다. 이것이 전통적으로 이러한 유형의 회사에서 3D SLS 프린팅 장비를 구현하는 것이 불가능한 이유입니다. 필요한 공간이나 가스 설치 또는 고전력 전기 공급 장치와 같은 기타 요구 사항이 없었기 때문입니다.

이로 인해 디자인 스튜디오, 엔지니어링 컨설팅 또는 소규모 프로토타이핑 회사와 같은 많은 기업은 역사적으로 이 기술에 수반되는 비용을 아웃소싱해야 했습니다.

이러한 예 중 하나는 일반적으로 FDM 또는 SLA 사용으로 제한되는 소규모 프로토타이핑 회사입니다. 그들 중 한 사람의 기술 이사를 인터뷰했으며 그는 SLS Sinterit Lisa 3D 프린터를 구입하여 자신의 서비스 포트폴리오에 SLS 기술을 추가한 경험에 대해 말했습니다.

F2P:좋은 아침입니다. Eloy. 3D 프린팅 및 프로토타이핑 세계에서의 전문적인 배경과 경험에 대해 말씀해 주시겠습니까?

E.B.:11년 동안 프로토타입 및 짧은 시리즈 제조에 전념하는 회사인 Eceleni의 기술 이사로 재직했지만 제 기원은 제품 및 금형 설계 모두에서 산업 디자인에서 비롯되었습니다. 광조형 기술을 처음 본 것은 20년 전 금형 작업장에서 디자이너로 일할 때였습니다. 진실은 그것을 가져온 고객이 우리를 떠나거나 만지지 않았다는 것입니다. 그 당시에는 아무도 3D 프린팅에 대해 이야기하지 않았고 스테레오리소그래피만 언급했습니다.

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.
