I have designet one that is BiPolar - [en.wikipedia.org]
It's still i alpha, but it prints. My friend (the software guy) and I will release it as a kit and we are gonna open source it.
Target is KISS, so no heatbed, high speed or high resolution. (it's at the moment 50 micron per step at outer cirle)
The atteched file is from the first prototype, we have secound running, but I have no pictures yet.
Jesper
ps. next version we have change all the parts in size so the printer can print it self. Bed is 21cm diameter and height is 16-20cm. Depending on Z-axis length :-)

That right there might be the coolest thing I've seen in 3d printing yet! Put a handle on it and make it ultra portable

How do you solve the printing issues at the centre of the baseplate? As far as I understand, that is the most problematic area in this type of printers. Also I was going to ask about straight lines, I hear they are too problematic with non-cartezian printers.
I like your design but i am contemplating about a solution that gets rid of linear rods, linear bearings but that wouldn't look so clean. I think the rotating geared arm around the linear rod is a touch of genius.
I would like to see this open sourced and have the community improve and speed its development. Any release date?
And btw, how much does it cost and is there a place in Europe It can be purchased?

One mor3 question if i may, what is the resolution on xy? Doesn"t the herringbone gear introduce backlash? Thanks.

Yes I was referring to the minimum resolution of the rotating arm. It is not even XY in the real sense but it's easy to express. That answered my question thank you.
Why aren't you considering an indiegogo or kickstarter campaign? People are well educated now about them and I am sure it's worth considering.
Thanks.

Well, some more details would help people decide. There are a few things that i don't quite get and which had me raise an eyebrow when reading them on the kickstarter page:
1) "Success rate is significantly lowered when using non-proprietary PLA and the raft might not work properly." I don't have a problem printing non-proprietary PLA and I never use rafts. Is this such a problem that needs a notice or is this more like a disclaimer to protect yourself from complaints? I wouldn't want a 300Eur 3d printer and buy 40Eur PLA.
2) [...]"using bipolar cylindrical coordinates solves a number of issues compared with most other 3D printers.".What issues does a cartesian or delta have that the bi-polar solves? As a big fan of bipolar printers for their compactness and simplicity, their achile's foot is exactly the bi-polarity, with poor performance when printing at the centre of the bed.
3) "In order to ensure high performance and lower costs we made custom electronics." Is it cheaper to produce this board than the alternative open source variants or have you cut down on features to keep costs down? Is there a list of features so we can see what it can do? What are the on-board capabilities of upgrading? Adding more fans, a heated bed?
The simplicity and the elegant solution made me drool about it but the above questions make me wait![]()
I am sure you will reach your goal as I can see the campaign looks like a hit after only a day.

Only available in Europe + USA, so that cuts me out immediately
But even if it was available, I don't think I'd back this project:
1. I'd hoped that, as mentioned several times in the campaign statement, the simplicity of the bipolar design would result in a significantly cheaper price than a Cartesian or Delta printer. But at 300 Eur + shipping, this is a lot more expensive than (say) a Prusa i3 kit from AliExpress, and it's a long way from being a proven design.
2. Needing an IOS (apparently not Android) or web app to run it is also off-putting. Presumably all the slicing and so on is done in the Cloud? It's also implied that this app is how you'll get new objects to print, rather than from (say) Thingiverse... this is another downside for me. Presumably all this is to make it user-friendly. But it looks to me like an attempt to lock your customers in. (Maybe I'm excessively cynical). A clear statement that you can import and print (e.g.) .STL files would be a good idea (assuming it is possible).
3. Interesting that it only mentions PLA filament. The hotend looks like a pretty standard item, so I can't see why it shouldn't also handle ABS, etc. Maybe it's just because the printer doesn't have a heated bed?
4. Before shelling out *any* money, I would want to see some specs of resolution, etc. How accurately can you place plastic at the outside edge of the platform? How straight does it print straight lines? What's the nozzle size?
5. I'd also want to see some specs about printing speed. How long (e.g.) to print that frog in highest quality mode? In lowest quality mode?
6. I wonder if the "centre of bed" problem *hasn't* been solved, and that's why the photo shows the green dragon being printed off-centre?
7. Are all the props in the photos printed with the Sculpto? Some of them look too shiny to be PLA.

I am sure you will reach your goal as I can see the campaign looks like a hit after only a day.
1. Sure it's a disclaimer, but I will asure you that we are not gonna sell our brand of filament for 40€ :-) I gonna be in the cheaper end.
2. you answered your own question :-) compactness and simplicity is what we think are a strong selling point for a family friendly printer and with big WAF :-P
3. I know we didnt include much info on the electronics, but our target audience is not maker/hackers so we didnt think it would mean much for most people.
But I will answer here. Electronics is gonna be 32bit arm based, with support for dual extruder, but no heatbed or extra fan (not our target again). It will have onboard wifi (with complete linux system). The reason for custom electronic is not only features or cost, but also to solve a lot of the cable mess other printers suffer from.
Hope that helped :-)
And have a nice day

Hi Kenzu, thanks for the info, I hope my questions weren't offensive, they weren't intended in that way. I just felt that some of the statements are a bit misleading and streched, for example claiming that the bi-polar solves some issues of other printers implies that there is something inherently flawed with other printers while this one isn't. Compactness and simplicity are quite obvious when you first look at the printer.
Having a 32bit board with wifi onboard is a big selling point from my pov, i like that. The simplicity in mechanics is thus accompanied by an equally simple operation.
I would like to see a "maker father"-friendly variant with a few more GPIOs to add fans, a heated bed and a second extruder. But that would mean that the power source must be larger which will increase the size.
Please don't be mad at the ones with a more critical eye, you are having great success with your targeted audience by the numbers on the kickstarter. We are the likes that would like your printer to reach its potential.
