Frequently Asked Questions

What is Selective Laser Sintering (SLS)?

In Selective Laser Sintering (SLS), parts are 3D printed in a layer-by-layer approach. A thin layer of powder is distributed onto the build plate. The laser then melts the areas of the powder that are needed to create the part. After that, another layer is applied on top and the laser again melts this layer of the part. The non-melted powder is used as a support structure which allows for intricate designs. Once the build is finished, the whole cake is cooled down and the non-melted powder is removed (mainly by compressed air). This powder can then be mixed with new powder and be used for the next build.

How can we find out if SLS is a technology for our production?

The first step is to analyze which applications in the company might be suitable for 3D printing. Important factors here are the number of parts needed, the complexity of the design and the material needed among others. Next up, the LSS experts use this information as well as a CAD file of the part to determine the practicability and the costs of using SLS for this part. We also do test builds to give you the chance for testing and finally deciding on whether SLS is a suitable technology for you.

If you are unsure whether SLS might be an option for you or where to start with the analysis, contact us. Our team is happy to help and guide you every step of the way.

How much maintenance does an SLS machine need?

Generally, the number of maintenance appointments needed varies depending on the number of hours the machine is running each week, age of the machine and ambient conditions. We do suggest, however, having at least one extensive maintenance performed by a professional SLS mechanic each year.

LSS offers various maintenance contract options for our own machines as well as machines from other machine producers. They can also cover technical support over our hotline, spare parts and repairs performed by our qualified service technicians. Contact us to find out which maintenance option is right for your machine.

Does LSS also maintain/ repair SLS machines form other machine producers?

Yes. Thanks to our extensive knowledge of different SLS machines across many industries, our service technicians are proficient in handling both LSS and non-LSS machines.

Where does LSS produce its machines?

All of our machines are designed and made in Germany – including the CE certificate. We work together with our national partners to ensure the highest quality in everything we produce.

What does “parameter open” mean?

Flexibility is a key factor to ensure that your SLS machines and equipment remain up-to-date with your changing production at all times. That is why all of our equipment is parameter open. It means that you do not need an LSS technician to change factors like density or tensile strength. Over 30 parameters can be changed by you. In case you need assistance, our technicians are happy to guide you along the way.

Are there financing options for the machines available?

Yes, our clients can choose among buying, renting or leasing the machine or payment by instalments. Our partner bank is happy to help you work out a payment option that suits your business.
