ProJet 1200: Versatile, Precise and Oh, So Much Fun!

As mentioned some time ago, the plan for this blog is to help users and potential users of the entire Cubify line of printers.  While, it's clear that a $4,900 3D printer is not within the means or needs of the vast majority of current readers, the ProJet 1200 is such a versatile printer that it is going to attract a lot of artist and designers who are really the impetus for me becoming interested in 3D printing in the first place.  In addition, it is a true "production" printer, capable of creating objects that can be directly used or cast using the "lost wax" technique for jewelry designers and dentists.

In fact, it is this ability to be used in actual occupational settings that spurred our interest at YouthQuest.  We want promising cadets to be able to get real-world experience related to real-world occupational opportunities.  The ProJet 1200 is a serious step in that direction.  The more I experiment with the ProJet 1200, the more I've come to believe that this little printer has the power to bring significant returns on the investment in the right setting.  For us, it will be enough if using the Projet 1200 encourages a cadet to pursue further education in art or as a dental technician.

The Physical Print Platform

It's a very SMALL printer.  The footprint is just 9"  x  9" with a height of 14".   3D Systems rightly compares its size to that of a coffee maker!

It is QUIET.  In fact, very quiet. There is no X-Y printjet motion.  The only sound comes from the Z-axis motor and it moves in just 30 micron layers.  That is just 0.0012 inches!

It is FAST. The micro-SLA process creates an entire layer at a time.  So, print time is NOT related to volume.  It is directly related to height.

There are two chambers in the ProJet 1200.  The left side is the print chamber.  And, the right side is used for curing the prints. 

You do NOT want to peak inside either chamber while printing and curing is going on.  I do wish, however, that there was a window of protective material that would allow us to see the progress of the print as print failures have consequences beyond normal FDM printers.  (More on that later.)

The Print Quality

Only one word does the ProJet 1200 justice when describing the quality and that is AWESOME! 

With multiple prints behind me, I can assure you that the promo picture on the Cubify site genuinely represents what I am able to achieve.

Unfortunately, the images I have taken with my phone don't measure up to the quality of the prints.  But, at the risk of embarrassing myself, I'm posting several.  The last image includes a quarter to provide some scale.  These prints are SMALL and SMOOTH!

The following are my favorites so far.  The one on the right is sitting on the quarter.  Click on the image to see it at full size.  The leaves are incredibly thin on the pendant to the left and the features incredibly sharp in the 'charm" on the right.  The supports you see were selected manually and were all that were used.  I think the leaves would be even cleaner had more side supports been applied.

Even the lack of sharp focus doesn't mask the sharpness of the ProJet prints.

Material Versatility

What makes the Projet 1200 such a versatile printer is the growing family of VisiJet FTX materials dedicated to difference tasks.  I've only had access to the Green and Clear.  But, those only whet my appetite for all the others.
If you clicked on the links in the list, you can see why I consider the ProJet 1200 to be an extremely versatile 3D printer.  The software adjusts the custom print settings for each material.

Warnings & General Observations

Don't buy this printer if you do not like to read directions. The ProJet 1200 may be small; but, it is no toy.  Care must be taken when handling the materials and the printed parts before they are cured.  In a future post we'll cover some of the precautions and "best practices".  We will also communicate how we learned the hard way to take the time to read the setup instructions.

Once the material tray is in place, do NOT move the printer at all.  (And... Yes, I did... costing me a lot of lost time cleaning the inside of the printer.  Very scary.

Failures, potentially, have greater consequences than with FDM printers.  I've had three support failures causing a buildup in the bottom of the material trays.  At $48 a tray, it's wise to learn the proper support strategy real fast.  I have a call into support to see if the trays can be rescued.  But, I don't think so.  User error is costly with this printer.

The other issue is that we may have to go through dealers for supplies.  I have not found a direct link to materials on either the Cubify or 3DSCentral sites.  Again, I'm looking into this.

The issue, it seems, is that the ProJet 1200 is a new category of 3D micro-SLA 3D printers that falls into a gap between consumer and professional.  I suspect the market demographics will sort it out over time; but, for now, finding materials is a bit confusing. 


I LOVE this printer.  It may not be my own; but, I feel privileged to be able to explore ways to add it to our curriculum. It is EXACTLY what I envisioned when I first started on my 3D Printing journey seeking solutions for my artist daughter.  Using Moment of Inspiration, creating takes minutes compared to days with manual techniques.  The next step is to explore casting for our 3D ThinkLink Lab and the cadets we serve.  This little printer expands how we can serve them with realistic occupational opportunities.  And, THAT is VERY cool!

In a future article we'll cover some of the mistakes we've made as we get acquainted with this printer and the consequences, as we come to understand them.  In the meantime, feel free t contact me directly if you are interested in investing in the ProJet 1200.  I don't sell them; but, I am more than happy to share what little experience we have with it so far.


  1. Wow I am liking the results posted. I will be watching as this progresses.

    1. You can understand why your tutorials on 3DCoat will be so valuable! It is a great design tool for jewelry and figurines. :)

  2. Nice! And your advice on personal protection from uncured resins is spot on. Imagine having some on you and going out in the sun? Instant cure.

    And just don't reach for the ProJet if you really mean to get a cup of coffee! ;-)

  3. I've tried to put a K-Cup in it 7 times already!

  4. Has anyone actually been able to cast the cast able resin, without using platinum investment for it?

    1. I have not tried casting either of the casting materials options. I only know that printing with FTX Green is a very different experience than printing with FTX Cast because of the wax component.
