Pallet 2

I saw a first gen at last years makers faire. was pretty cool. But those are expensive

tax time toy. yea it is cheaper i see

What is the advantage over 4 extruder mod? Seemed to be over complicated mechanism to switch color.

There is a lot to the system And you can move this from one printer to another if needed .
There is no need for 4 different hot ends and the motors are integrated into the mosaic pallet unit.
Give them a couple years and likely the price will drop again and more improvements will be integrated.
That seems to be the normal cycle of R&D.   
This is a fairly new concept in 3d printing to be able to print in full color. This may lead to full color blending where you have 5 colors black, white , red blue and  yellow and the machine blends accordingly.
m . This system more than switches color it integrates them into the print or various materials.
It is admittedly a bit pricey the Retail price on the Pallet 2 is roughly twice the price. of the similar Prusa Unit priced at $299. The mosaic team has put a lot into this including software development.
The mosaic is designed to be used with many  most printers. I can also see this being used for large printers as it can be set if one filament runs out it simply feeds the next one in. so one could simply load 4 rolles of the same color and let the thing print for days.

You need to decide if this product is something you need or want and if the price is right for you.
This is just one of the bleeding edge technologies on the market. like i mentioned Prusa had a similar unit and E3d has the 4 tool head printer. that has a lot of potential.

I guess that why you a doctor and not an engineer.  But you seem to know better than the engineers ......

I was going to be a computer engineer after college, but my mom make me quit and become biomedical scientist.

When I was on computer engineer track, what I learned is engineer and marketing people want different thing most of the time. Whatever engineer want to make may be fancy and advance but they never make enough money. I sometimes wondering if I should switch my career goal to marketing, they can always sell low tech product and make a lots of money and decide to fire half of the R&D team. I was in the only R&D team that they decide to keep and my mom make me quit.

BTW, the point I made is from evolution angle, creatures evolve fancy and complex system to do simple task always dies off faster, not from engineering angle.

I don't like old tech, but for the new tech, it has to be simple enough to become popular. It is somewhat true that new tech always somewhat more complex than old tech, but the success new tech find ways to package the complexity so that it appears to be simple for end users.

Pallet 2 use complex mechanism to do simple task, it has some advantages, but they are not killer application for stuff asking that price. Believe it or not, they will come up with the automatic filament loader sooner or later, if they price it $75-150 depend on how many spool you can load, at least 1/3 of people own 3D printer will get one. Material production cost can be as low as $20 for 2 extruder version.

Tin, don't get me wrong, I do like your post. I think it introduce a new technology to reader. I hope my comments did not discourge you post this kind of information. I want to thank you for continues effort in bring in new knowledge to us and I learned a lot.

I don't think I can do better to make better Pallet either, with all do respect, Pallet engerneer done great job to make current version as good as it is. However, the solution born with its limitations to do what it is defined to do currently. I don't know much about the finacial situation of this company and hopefully they have enough founding to support till their product mature.
