BCN3D Sigma Prints 4
A reliable machine wigh good repeatitivity.
Use with various materials. The extruders are accurate and very versatile.
A real workhorse
The BCN3D Sigma R17 is not only very reliable, it is a real workhorse that offers you limitless potential.
Fast, large and with a good quality
One of the few options available when looking for a large build size, dual extrusion and good quality. Perfect results in combination with Simplify3D, which is unfortunately not included in the purchase. When using Cura, quality and speed is not optimal.
Not Happy with Machine quality of print is not that good
My biggest gripe is the Firmware - Buggy - lets face it its a dual head machine and it crashes when unloading the filament on the Right Head MM and how long has this been on the Market. Also getting the Z height right is a pain, and on the last Note it is supposed to connect to Windows 10 well it fails abysmally , even the drivers you get from them.. UM2 just connects, if I use there drivers on a windows 7 machine no problem. windows 7 is going out of support,
Without a doubt thus far, one of the best 3d printers out. I've used cel-robox, xyz davinci aio and pro, very nice machines for hobbyist, but if you want something you can rely on over and over than the Sigma is the one. The Sigma is right up there with the Ultimaker line if not surpasses. I can't say anything bad about the Ultimaker 3d printers, but I do know they tested side by side and the Sigma can beat them in print times and the quality is even. The only thing I wish the Sigma had was WiFi capabilities and an app for the cell phone, to watch over it. With this said, the reliability is well enough, that you don't need to babysit it. Now that Octopi by OctoPrint is available the wifi problem is solved. Great Printer
it's my favourite printer
Sigma / SigmaX
Like everything else in life nothing is perfect, but you can get really good results once you get to know the machine. I mean really, really good quailty prints.
The main downside is the calibration is very susceptible to human error which is something we're working on improving. Aside from this the printer is very flexible and capable of things most costumer aren't aware of (plus new funtionalities we're including on the next release).
We're countiniously developing and improving our 3D printers to provide the end user with a better printing experience, workflow, as well as a more robust and reliable machine
Thumbs Up for the BCN3D Sigma
I love this machine.
I've used several different FDM machines at work, so have a little experience with Makerbots and Chinese implementations of the robust Ultimaker design.
The Sigma (R16), however is in a class of it's own.
So what do I like about this machine:
- The IDEX system works well to reduce the mass (and vibration ) of a more weighty head.
- The latest version of BCN's implementation of the tried and tested Cura software is truly excellent. Use it out of the box ,or tweak the devil out of it, it's all you need.
- The touch screen menus and interface get better with each firmware iteration
- The swap in swap out hotends, while not a slick as the Makerbot 5th Gen Smart Head, make changing nozzle sizes fast and convenient enough.
- The all welded aluminium cabinet/frame is rigid yet light.
- It looks great.
What don't I like:
- It's a noisy beast. However I haven't yet done the two recommended hardware upgrades yet.
- Other than that, there's not really anything that isn't common to all FDM machines
What would I like to see in the future:
- How about a couple of cable chains rather than those clumsy flat ribbons hanging from the bowden tubes?
Regarding community support; I just haven't had the need. There was a bit of an issue with the USB interface when I first fired it up. No one seemed to know how to fix that. However a subsequent firmware upgrade fixed the problem.
Nothing is perfect, but overall, this is a really great machine.
