Want your own SLS printer at a reasonable price?

Have you ever wondered what it would be like to have your own SLS printer? I have, and the frustration associated with the availability of this technology has been really huge. So from this point it was a small step to a silly idea – I’ll make my own SLS printer concept. It took me over 3.5 years, but it’s here, open and ready for you!

Looking for a special 3D printing experience?

SLS is truly another world. If you really want to try and understand this technology, Inova is a great starting point. It starts with the build itself and continues with the ability to touch dozens and dozens of printer parameters. But no worries – our assembly instructions will be your good friend and the software solution will allow you to use the printer without any knowledge if that’s the approach you prefer.

Do you dream of 100% design freedom?

Probably everyone who creates own 3D parts/models has had to struggle with the limitations of FDM and SLA printing. Gravity is relentless.  Supports do work, but everyone tries their best to avoid them because they always spoil (more or less) the resulting print surface quality. For simple models this is often acceptable, but for models with complex geometry, FDM or SLA are often not the right choice. SLS is the only 3D printing technology that does not require supports. 

Need mechanical, chemical and temperature resistant parts?

That’s my favorite thing about the SLS. Since I mostly design functional parts I really appreciate their mechanical, thermal and chemical properties. When I think of the problems related to the printing prototype parts in nylon on my FDM printer, I’m glad I have another option today.

Interested in efficient small batch production or rapid prototyping?

If you design or manufacture your own functional products using 3D printing, SLS is the right choice. Since SLS doesn’t just use the print surface, but the entire volume above it (the print chamber), it is the ideal tool for small-scale manufacturing. You can print out dozens of small to midsize parts in one job.

Compared to prototyping using FDM or SLA technology, you not only assess the design and dimensional requirements in each development iteration, but also verify their operational/functional durability.

Do you like open source projects?

I believe that sharing knowledge will enrich us all and move us forward. In addition to enabling DIY production of the Inova printer, I see open source approach as a powerful tool for technological advancement. I’m already curious to see if a strong and creative community will emerge around SLS4All that will take what I started a light year further.

Build It & Enjoy Your Prints!

Main characteristics

Printer is particularly suited for rapid iterative prototyping and/or small batch production. Since SLS is the only 3D printing technology that prints without supports, you can design your parts without limits. As the main material is PA12 Nylon based powder, the printer is primarily designed for functional parts with higher mechanical, thermal or chemical resistance requirements. But printing of soft TPU based parts or experimenting with other materials with melting point under 200°C is also possible.

Build

We’ve done everything we can to make building the printer a fun and enjoyable experience that you can enjoy while understanding the basic principles of how the printer works. I expect you to be able to build it in say 4 to 7 daysNo worries if you don’t have any previous experience with building 3D printers or any other complex projects. Our interactive assembly manual will help you to overcome any issues with ease.

Operation

Once you build the printer, we believe you will forget that it is a DIY product. Our software solution, which is full of wizards and contextual cues, will give you a quick and easy learning curve leading to successful prints.

Selective Laser Sintering: Why Not To Make It Affordable?

It has been fairly over a year since I started to work on my DIY Selective Laser Sintering (SLS) 3D printer project.
