[rp-ml] MCor Technologies and the ArKe

That’s not my experience. My collection has several objects made by LOM, as well as by Kira’s similar technology and by Ennex in our experimental Offset process, and none have shown any degradation or contortion over time.

It may be telling that this is the second time a prominent paper based technology for 3D printing has come and gone.  (LOM was the first/)  Paper does not stand up well to the environment.  At one point I experimented with sealing MCor parts and they just won’t hold their shape.

Hello, List,


There has been no chatter on the RP-ML about the rumored demise of MCor Technologies, 

maker of the ArKe.

There are two articles in the mainstream press that I know of:
Receiver for 3D printing firm Mcor  by Gavin McLoughlin 
Independent Business Irish March 29 2019 2:30 AM
The End Of Mcor Technologies? by Kerry Stevenson
Fabbaloo 30 May 2019

I am personally very disappointed to hear this news.  And apparently, the founders, the 

MacCormacks just stepped down from leadership positions at MCor this January.

Some of you might remember that I used to supply exotic STL files to the R-P  vendors for you 

to show off your building skills at the trade shows.

In 1999, when the Z-Corp Spectrum was announced, I jumped right in creating VRML files in 

color, some of which wound up at the trade shows as well.

I actually got to run a Spectrum 500 around 2008-2009 and got to learn all of its color rendition 

quirks.  There are many.

By comparison with the  Z-Corp Spectrum, the MCor ArKe's color reproduction looks 

spectacular -- and least, "It looked alright in the pictures" (--Lorde)

I began corresponding with my local MCor ArKe reseller, Andy Grayson at RAPID SCAN 3D at 

the end of January.  I haven't made it very far, presumably due to this receivership business.

Here's what I have gathered from my correspondence with Andy Grayson at RAPID SCAN 3D 

and from the above articles.  Apparently there were at least demonstration machines which had

been sent to the resellers. But, by this time I contacted Andy Grayson at RAPID SCAN 3D, they

no longer had theirs and were waiting for a new one.

It looks as though the MacCormacks had taken MCor from the demonstration stage up to the point of actually going into production and full-blown commercial sales, but investment funding to get past that point had stalled.

I think that is a pity.  I really had plans to design objects for this machine specifically.

Are there any users out there who still have MCor ArKes running?

I would really like to see how my designs come out on them.


Thanks and cheers,
