Kasus sukses implementasi teknologi SLS dengan Sinterit Lisa di biro jasa
Sejak diluncurkan di pasar, printer Sinterit Lisa telah menjadi sebuah revolusi. Ini adalah printer SLS terjangkau pertama dalam format desktop. Kualitasnya yang tinggi, kemudahan penggunaan, harga yang murah, dan ukurannya yang ringkas menjadikannya ceruk di sektor-sektor yang hingga saat ini dianggap tidak layak untuk memperkenalkan teknologi ini.
Salah satu sektor ini adalah biro jasa , bisnis yang memberikan layanan kepada perusahaan lain dan dapat berupa desain, teknik, atau konsultasi. Salah satu kekhasan dari jenis usaha ini adalah umumnya berlokasi di perkantoran. Inilah sebabnya mengapa secara tradisional tidak mungkin menerapkan peralatan pencetakan SLS 3D di perusahaan jenis ini, karena tidak memiliki ruang yang diperlukan atau persyaratan lain seperti instalasi gas atau pasokan listrik berdaya tinggi.
Hal ini menyebabkan banyak bisnis seperti studio desain, konsultan teknik, atau perusahaan pembuat prototipe kecil secara historis harus menggunakan alih daya teknologi ini, dengan biaya yang diperlukan.
Salah satu contohnya adalah perusahaan pembuat prototipe kecil, umumnya terbatas pada penggunaan FDM atau SLA. Kami telah mewawancarai direktur teknis salah satu dari mereka dan dia telah memberi tahu kami tentang pengalamannya menambahkan teknologi SLS ke portofolio layanannya dengan membeli printer 3D Sinterit Lisa SLS.
F2P: Selamat pagi Eloy. Bisakah Anda ceritakan sedikit tentang latar belakang profesional dan pengalaman Anda dalam dunia pencetakan dan pembuatan prototipe 3D?
E.B.: Selama 11 tahun saya telah menjadi Direktur Teknis Eceleni, sebuah perusahaan yang didedikasikan untuk pembuatan prototipe dan seri pendek, tetapi asal usul saya berasal dari desain industri, baik dalam desain produk maupun cetakan. Pertama kali saya melihat stereolitografi lebih dari 20 tahun yang lalu, ketika saya bekerja sebagai desainer di bengkel cetakan. Yang benar adalah klien yang membawanya tidak meninggalkan kami atau menyentuhnya. Saat itu tidak ada yang berbicara tentang pencetakan 3D, hanya stereolitografi.
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.
