Focus started of in October 2012 when I asked myself, how hard can it be to SLS nylon powder. To answer this question I built Focus. I have designed Focus to be experimental, All parts can be swapped for different parts and there is a lot of adjustments in most parts.
I myself have configured focus as a SLS/SLM printer right now. I have had the best results with laser melting Nylon 2201 powder. you can follow updates on focus at it's blogspot page. Focus is still a work in progress so expect parts and software to change.
In this instructable I have included everything needed to build the basics of focus. This includes:
- Wiring diagrams
- Technical drawings
- Bill of material lists
With this you can build the printer. The toolhead will have separate lists in their respective steps.
Sadly there are no step by step building pictures of Focus. Focus has changed a lot since I started work on it. I have tried to compensate the lack of step by step pictures with good technical drawings.
If you still have questions after reading this instructable, feel free to ask them in the comments.
