Does EventorBot answer my prayer for a reliable 100-micron layer printer? You guys told me that in order to print 100-micron layers reliably, the printer must have a solid build, with a good transmission system (with timing belt tensioner etc...) and with stepper motors that have small enough step. I saw a printer called EventorBot: [www.eventorbot.com] that has a solid welded frame (instead of extrusions / rods joined by printed plastic connectors). Will the welded frame of EventorBot answer my prayer of a reliable 100-micron layer printer? Though one thing I worry is that the print platform cantilevers with the vertical beam, so how can the print platform be parallel to the top beam that forms the track of the nozzle? If the print platform is not exactly parallel to the top beam, will it be difficult to have consistent 100-micron layers? Has anyone used the EventorBot printer (kit or fully-assembled/calibrated)? What do you think about its quality? And how well it perform in making 100 micron layers? Finally, what is the maximum hot-end temperature of EventorBot? Apart from PLA and ABS, I also plan to print in polycarbonate, which I believe requires an hot-end temperature of 280C-300C. https://reprap.org/forum/read.php?4,185259,185259#msg-185259 Sun, 19 Jul 2026 17:24:31 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,185259,186207#msg-186207 Re: Does EventorBot answer my prayer for a reliable 100-micron layer printer? https://reprap.org/forum/read.php?4,185259,186207#msg-186207 xclusive585 Reprappers Wed, 20 Feb 2013 10:39:17 -0500 https://reprap.org/forum/read.php?4,185259,186102#msg-186102 Re: Does EventorBot answer my prayer for a reliable 100-micron layer printer? https://reprap.org/forum/read.php?4,185259,186102#msg-186102 -------------------------------------------------------

So in another word, any printer that have beds moving within a layer (including Up! Plus,and even MendelMax) will have the same problem, right?

When you say you are worried about the quality control of Eventorbot, why are you specially worried about Eventorbot? And do your worries on Eventorbot apply on any welded-frame printers?

Finally, what would you choose for a FDM/FFF printer that does 100 micron layers *reliably*, and possibly 50 micron?]]> markfarnell Reprappers Wed, 20 Feb 2013 02:41:52 -0500 https://reprap.org/forum/read.php?4,185259,186094#msg-186094 Re: Does EventorBot answer my prayer for a reliable 100-micron layer printer? https://reprap.org/forum/read.php?4,185259,186094#msg-186094 The difference is the bed doesn't move while it's printing, just between layers.
The thing that would worry me about the eventorbot is quality control, if that welded frame isn't straight you'll never fix it.

People print at sub 100 micron on ordinary mendels, but they have to be well assembled debugged and you have to spend the time calibrating.
In this hobby printer A doesn't equal printer B even with identical designs and components because build quality really matters.
Even if you could by a calibrated printer who knows how much of that calibration would survive shipping.]]> Polygonhell Reprappers Wed, 20 Feb 2013 01:37:06 -0500 https://reprap.org/forum/read.php?4,185259,186091#msg-186091 Re: Does EventorBot answer my prayer for a reliable 100-micron layer printer? https://reprap.org/forum/read.php?4,185259,186091#msg-186091 -------------------------------------------------------

Thanks for pointing this out! When I saw the carriage cantilevers in this fashion, I also had some doubts how stable this is.

So am I correct to say that if I were to look for a printer that has sufficient stability to print at 100 micron layer accuracy, the platform of the printer needs to lie flat at the bottom, and the print head is the one to move up and downwards?

Also, would a printer that has a completely static print platform with the print head moving in all axis be a better option?

On this ground, would a design similar to the MendelMax 2 be a more suitable candidate as a 100 micron printer?]]> markfarnell Reprappers Wed, 20 Feb 2013 00:52:09 -0500 https://reprap.org/forum/read.php?4,185259,185984#msg-185984 Re: Does EventorBot answer my prayer for a reliable 100-micron layer printer? https://reprap.org/forum/read.php?4,185259,185984#msg-185984


The actual print bed is a plastic plate which attaches with spring-loaded bolts to the outermost black frame. It's supported over very small section in the arm and the arm in turn is supported by a very small section inside the vertical pillar – the pillar only has very closely spaced rods and linear bearings for that, while having to take the torque produced by the Y-carriage moving back and forth.

I would be amazed if this design could print at 100 micron layer accuracy at any reasonable speed even if the steel frame itself was infinitely stiff. The whole Y-carriage is going to vibrate a lot (which is also what the build threads linked above seem to report).

The eventorbot has not been yet released...But you can find some personal builds here:

With all printers, the print platform needs to be level at all corners with the the print nozzle.

For polycarbonate you are getting into a temperature range that would require an all metal type hot-end to get any kind of durability over standard hot-end designs.]]> Dirty Steve Reprappers Sun, 17 Feb 2013 00:12:56 -0500 https://reprap.org/forum/read.php?4,185259,185259#msg-185259 Does EventorBot answer my prayer for a reliable 100-micron layer printer? https://reprap.org/forum/read.php?4,185259,185259#msg-185259
