在服务局使用 Sinterit Lisa 实施 SLS 技术的成功案例

自推出市场以来，Sinterit Lisa 打印机掀起了一场革命。它是第一台经济实惠的桌面格式 SLS 打印机。它的高质量、易用性、低价格和紧凑的尺寸使其在直到最近还被认为无法引入该技术的行业中占有一席之地。

其中一个部门是服务局 ，为其他公司提供服务的企业，可以是设计、工程或咨询。此类业务的特点之一是它们通常位于办公室。这就是为什么传统上不可能在这类公司实施 3D SLS 打印设备，因为它没有必要的空间或其他要求，例如气体装置或大功率电源。

这导致设计工作室、工程咨询公司或小型原型制作公司等许多企业历来不得不求助于外包这项技术，并承担由此带来的成本。

这些示例之一是小型原型制作公司，通常仅限于使用 FDM 或 SLA。我们采访了其中一家的技术总监，他向我们讲述了他通过购买 SLS Sinterit Lisa 3D 打印机将 SLS 技术添加到他的服务组合中的经历。

F2P：早上好，埃洛伊。您能告诉我们一些您的专业背景以及您在 3D 打印和原型制作领域的经验吗？

E.B.：11 年来，我一直担任 Eceleni 的技术总监，这是一家致力于制造原型和短系列的公司，但我的起源来自工业设计，包括产品和模具设计。我第一次看到立体光刻是在 20 多年前，当时我在模具车间做设计师。事实上，带来它的客户并没有离开我们，也没有碰它。那时没有人谈论 3D 打印，只谈立体光刻。

F2P：在 Eceleni，您同时从事减材制造（CNC 加工）和增材制造（3D 打印）以及成型（快速硅胶模具）工作。与其他技术相比，您认为 3D 打印可以提供什么？

E.B.：在大多数情况下，3D 打印可以制造无法制造的几何形状（例如 Lattices 或 Voronoi），并且可以在制造短系列或原型时立即使用。虽然对于比较大的工件来说，加工的期限和成本确实更好，而且根据数量，培训技术仍然是最好的选择。

F2P：目前你们通过 Polyjet、FDM 和 SLS 提供 3D 打印，与其他两者相比，后者给你们带来了什么？

E.B.：SLS 技术比 FDM 技术具有更好的表面光洁度，并且比 PolyJet 具有更高的机械阻力。例如，SLS 制造的弹性体比 Polyjet 的柔性树脂具有更优异的抗断裂性。

F2P：在您的设备中有 Sinterit Lisa 3D SLS 打印机，您能告诉我们您为什么选择这款 SLS 3D 打印机而不是市场上的其他型号吗？

E.B.：与 SLS 中的其他选项相比，它是性价比最高的。 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.
