Something that is not mentioned on your page, on the wiki or here is if this is metric or imperial?

This of course changes the price of the hardware in various places, and I know that some people, especially outside the US, will not buy imperial even if it is available to them.

Yep, we should have mentioned that. It's metric. We plan to do an imperial one eventually because that reduces the cost of hardware in the U.S.

Are you already sold out?

We sent out our first shipments this morning! We have most of the parts produced for a couple more kits, so we expect to be able to ship new orders out quickly.

I'm working on cleaning up the Alibre assembly files and hope to have them posted today on the Wiki. I also hope to have a hardware list up today or tomorrow. Documentation is still in the works.

I ordered a kit last week and it has already arrived! All the parts seem to be there, and they did a really nice packing job. Now just waiting on the mechanical parts, and the building can begin.

I'm pretty new to the whole RepRap scene and I am currently considering to build a Mendel.
Therefore I'm clearly not experienced enough to determine the 'long term' effects of going for the Isaac instead of an original Mendel in terms of what existing help/electronics/etc... i could reuse. --> ???

I don't even know what material those parts are made of. (3 years ago I build a 6 legged walking robot using 'Lexan') Is that mostly wood? How does it compare in terms of durability to those 'original' PLA/ABS parts?

Thank you in advance!

Best Regards,

The materials that we are currently using consists of Trex (a recycled wood and plastic product) for the larger parts and HDPE for the smaller. Both are very rigid and should last a long time. When they fail you can print replacements just as for the original. You can even replace them, and axis at a time, with the original if you add hardware (nuts/bolts, not electronics).

I know of one person who has bought individual axis parts from us and is using it in conjunction with original style axis. Maybe someone who has bought a kit con jump in on quality/durability/design opinions.

As far as most everything else goes, it shares the same size and lengths of rods/nuts/bolts/electronics just much less of all of it. I'll attach a BOM so that you can compare it to the original. The resulting print area is identical as are all the critical dimensions. As I said you could replace them an axis at a time.

Existing help consists of me and my brother until others finish their kits. We are fanatical about supporting this and will do whatever is required to make sure your build goes well. I'm pushing hard this week to produce better documentation and exploded views (sample attached) of everything for easier reference.

Hi Brett,

thanks a lot for the information.

I really like that I could transform it into a 'original' Mendel.

So to conclude:
So what you are doing is similar to those 'Complete Laser Cut RepRap Mendel w/Electronics Kit' (except you don't sell the metal and electronics stuff, which btw makes it a lot more interesting for somebody new like me!), mechanically slightly differing from the 'original' Mendel, so that they can be made with a CNC machine, while one can use 'original' electronics, motors, software to either convert it into a 'original' Mendel or just print a new one.

Best Regards,

You summary is correct, and it is similar to the Laser one which just recently came out.

We will start offering other bundles as time permits but you can already build an Isaac cheaper than the current price of the Laser one. You could build either a lot cheaper if you know someone with a CNC machine or Laser cutter though smiling bouncing smiley.

I stand corrected on the price. The going rate is $210 for the laser cut Mendel so we've adjusted our price to match at $240 which includes all the pulleys and belts which would cost you around $50 to buy anyways spinning smiley sticking its tongue out

To further encourage new members to join the community, every once in a while we'll offer up a no-reserve auction on eBay for one of our kits.

The eBay Auction is here.

Good luck smiling bouncing smiley
