    How to Design a 3D Printer

    I'm pretty sure it's very similar programatically as having two extruders (I'll have my friend fact check me in the morning). This end also allows color mixing, which is a little more complicated, but it's made by reprap, so they have tons of documentation. You just have to have a board which allows 6 servos total (3 movement, 3 feeders). There is also a facebook group for the diamond hotend, and they've been more than happy to help people out.In simplify3D, you just add another tool in the process settings, so it's pretty easy. I haven't done anything in multiple colors yet on this printer, but the process I use with my flashforge dreamer is:1. Design an assembly in Solidworks2. Save assembly as an STL (make sure you export them as separate files)3.

Control click center and arrange or make sure that they all have the same origin5. Create a custom process for each part and only have each process apply to the specific colored part 6. Print using all of the processesThe important thing is that you make parts that are separate files with a common origin that lets them line up. I'm not sure how this works in other programs, but I'm sure you can find the proper way to make assemblies in whatever program you use. Does that help?

    How to Design a 3D Printer

    I'm trying to fix a homebrew delta for a friend and I really don't like them. It's almost as tall, but has half the build height and is a general pain. Calibration is proving difficult as well as accuracy. I can see the advantages, but I decided to build what I know and go for an xy machine. Plus, a delta would struggle with the hotend we used.The cube is about 1-1/4" cubed, so they're relatively small. We haven't printed anything huge on it yet. We want to set up the sd card reader before we do that. (So we don't have a computer tied up for too long)Thanks! I'm hoping to do it before my membership runs out, so I'm working on getting all the documentation in order and making the final tweaks and improvements done within the next month or two.

    My friend is the guru for those, I'll have him answer your question when he gets back. We used Nema 17 servos for the xy axis and a Nema 23 for the z axis (I'm pretty sure they all came from openbuilds). I don't know much about the drivers. We based what we bought off of the drivers that came with the diamond hotend, they were a bit overpriced though, so we just bought similar ones off of amazon. Sorry I can't help more, again, my friend will be able to answer those later today.

    Duct tape isn't great for anything, but it works for a lot of things!

    How to Design a 3D Printer

    We kinda did actually. All of the red and black parts in the xy axis were printed on my flashforge. (halfway there, right?)

    We used a Megatronics v2.0 from sainsmart with modified marlin firmware. We use Simplify 3D for the slicing. Does that answer your question?

    How to Design a 3D Printer

    I plan to post an in depth instructable for my design, but our documentation just isn't where I want it to be yet, and there's a bit that I still need to take care of. The total cost was somewhere around $1500. That bought us a diamond hotend triple extruder and a 1'x1'x3' build volume. I can maybe help you get started if you're interested and want to start sooner rather than later.

    Thanks, it's been a long road and both our sets of parents are awesome. They've actually been VERY supportive of our projects (I was raised around tools, so it was kinda my dad's fault). College has taught me just how nice supportive parents and family are. The jury is still out on how well our careers will go, but engineering is awesome and pays well, so I'm feeling positive.Seriously though, if you wish you had one, you can get them for under $300. It can be a time consuming hobby (they're just not easy to use yet) but I personally love it. Most people who spend time with me know that I talk about it WAY too much. Eventually I'll make a step by step for our specific design, but it's a bit on the expensive side, we still want to tinker with some stuff on it, and the documentation is a ...see more »Thanks, it's been a long road and both our sets of parents are awesome.
