Assembling a Sintratec Kit can take a few days and it’s a rather complicated process. Here are the videos we made of how we assembled our unit and got it calibrated for 3D printing.
The process contains several steps: Door, Base, Core, Lamp, Hat, and Electronics. Each step takes about a half day to complete, and Sintratec expects the average assembler to allocate approximately four full work days to the assembly process. That’s a pretty conservative estimate unless you have some experience tinkering on things. This project required a lot of room to lay out all the parts, some decent experience with electronics and mechanics, and if you want the job to go faster, some additional tools that are not provided with the kit:
The assembly videos will be listed below. They are a bit long, because we didn’t want to edit out all the complicated or confusing bits from the shot. If we encountered something that didn’t make sense or didn’t fit together, it’s in the video so you can learn from how we resolved that issue.
The first part of the assembly project is making the door. Seems like a simple task, but the door has a lot going on. Two layers of protective glass, a layer of laser-glass, various types of aluminum sheeting, thermal insulation, and other components. It’s a great way to start off the build, because if you can’t handle making the door, you probably shouldn’t move on to the rest of the assembly. (3D Chimera will offer to assemble your kit for you, for a fee).

The second major step in the process of making a Sintratec Kit, is the base. The base is basically a box filled with insulation to act as an oven for the printer volume. Since sintering requires 300+ degree ambient temperatures, you need a good solid base with effective insulation to protect against heat loss and burns.

The lengthiest part of the entire project is assembling the “Core.” The Core contains the moving parts of the build (like the applicator fin, pulleys, elevators, etc), as well as the volumes for the supply-, build-, and overflow-bins. It resides in the Case (shown above) and is removable for maintenance, if necessary.
The core assembly videos will be broken up into chapters. Part One of the Sintratec Kit Core assembly is located here:
In the following weeks, we’ll post more videos of the assembly. We’re editing these things in between projects and the videos tend to get put on the backburner. As you can see from the various articles on this website dealing with our Sintratec SLS Printer, we already have this built and it’s working well. We filmed the whole process, and the hours of footage are just hanging out until we get to them. Eventually we’ll get the whole assembly on here.
