Laser Sintering Optics: How To, Part 2

I'd like to continue in the topics related to the optics used in my laser sintering printer. In my last post I have already touched the problematics of the suitable laser sources, described why I choose the laser diodes instead of e.g. CO2 lasers, how does the beam shape look like and how to change and collimate it. I ended up with the finding that...

Heated Chamber Is The Holy Grail: Let’s Make It!

Initial design as well as the electronics setup and firmware selection were behind me so I could move to the Inova build itself. Although it took me a few months to get to this point, now I can shout: “Yes, let's the fun begin, heated chambers and beds are waiting!”.Those words did indeed run through my head, but the spontaneous joy was rather quickly replaced...

Printer Frame Build In A Few Simple Steps

Frame of the Inova SLS 3D Printer is not the most complicated thing in the world. But despite that, it still has to fulfill some specific requirements. Biggest challenge was to design the printer frame in the way to accommodate all the heated parts and at the same time to hold the heat only in frame areas where is needed. Here are several reasons for...

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. I didn’t think it will be an easy one, but it is much more complicated than I expected. On the other hand, this complexity is also the main reason why I decided to share it.I like the basic goal of selective laser sintering...

PA12 3D Printer: Recoater Under The Focus

Manufacturing of the recoater assembly was a pleasure. That was because I did a lot of work at my old-fashioned lathe machine. It is something, I really like to do. In accordance with my Fusion 360 design, I went for the layout containing counter rotating roller even it is not the simplest approach. Despite, it is often used by “big guys” of the PA12 3D...

Klipper Firmware, Raspberry & BTT: For Me The Best Combo

I decided to use the BigTreeTech 1.4 Turbo control board and Raspberry Pi 4B both running the Klipper Firmware to control my Inova SLS 3D Printer. If you are interested why and how I came to that, read further. To be able to determine what I will need in terms of electronics and its overall architecture, I had to define all the components to be...

Fusion 360 3D Printer Design: The Most Important Parts

Once I have finished the state-of-the-art search in the field of SLS printing, printers and related DIY projects I moved to first step of the project – features definition and Fusion 360 3D Printer Design. Having in mind I want to have the printer not to be slower than FDM printers, making nice complex prints and be user friendly, I had to make some decisions...

SLS Laser & Optics: How To Make It, Part 1

One of the tricky parts of the Inova SLS 3D printer project was the arrangement of the optical components. Basically, it was not too complicated topic itself, but it was completely out of my experience and focus field. I had just general idea how should the SLS laser and optics’ arrangement look like and didn’t know any of specific details. If anyone reading this post...
