Re: Introducing The Mendel Uni-body - 16 years ago

Hi Carlos This design is still in the prototyping stage the current step is getting it up and printing (there has been some delay due to faulty electronics) then there will be some final redesigning. There are still a few factors that need resolving before thinking about some form of mass production, mainly the weight and quantity of plastic used are a bit too heigh and assembly time is still

Re: Introducing The Mendel Uni-body - 16 years ago

hi Johnycooper Think you made some good points, as to the STL files unfortunately i don´t have any, what i do have though is images that are plan views of the parts on 1 cm gridded paper and pretty much all the parts are 1.8 cm thick so it gives a good idea of the dimensions and form though obviously not exact, that´s the best i can do for the moment.

Re: Introducing The Mendel Uni-body - 16 years ago

Hi I think a few people were looking for a video of the frame with the electronics on it so i rustled one up, this is the one i´ve been experimenting on and am setting the electronics up on at the moment so it´s a bit rough round the edges but other wise it´s pretty much exactly the same as the one above, here it is with the motor cogs being turned.

Re: Introducing The Mendel Uni-body - 16 years ago

Hi martinprince2004 The parts were made from cold casting as you said. Thanks for the tip on the Nylon glass I wasn´t aware of it, I tried a few fillers (metal filings and a general filler) both were unsuccessful, so i need to go on researching.

Re: Introducing The Mendel Uni-body - 16 years ago

Hi markus The nylon bars are definitely a concern, they are well constrained by the bearings holding them at each end and i am confident about the strength of the thread on them but, the nylon is quite flexible though. I spent quite a bit of time working on casting them with stainless steel bars in side them as a reenforcing with good result but in the end had to give up because i wasn´t sure a

Re: Introducing The Mendel Uni-body - 16 years ago

Hi Freds I actually first made this out of MDF, plywood would work fine too though, so it works well as a quick and very cheap(about 25 euro for the materials, bearing and all) way to make a repstrap.

Re: Introducing The Mendel Uni-body - 16 years ago

Hi Gene For sure there´s failures to this approach to the mechanics, using plastic, molding and glue definitely lends it´s self to a less flexible system and the kind of problems with repairs and upgrades that you mentioned. But on a particle level glue would seem to be the best solution for repairs along with a supplier for parts . Stress relaxation could be a problem, as i´m not an expert on

Introducing The Mendel Uni-body - 16 years ago

So I´ve been working on redesigning Mendel´s mechanical parts for the past couple of months. Looking at a few different things but mainly trying to simplify it all by integrate the metal and plastic parts to create a uni-body that´s pretty much all-plastic (except the bearings) and made from a single casting process. This basically stream-lines the whole production and assembly. The other main

Re: Mendel printer up for auction - 16 years ago

Hi Carlos To answer some of your questions let me give the printer a little bit of context. I under took the project of assembling this printer to get a better understanding of the mechanics and electronics involved in a 3D printer. This is what i have done, the printer is assemble 95-99% according to the Reprap instructions on this site, That much i can assure you and the images testify to th

Re: help with electronics - 16 years ago

Hi wayland, thanks for the help, it´s the wright capacitance (100 uf), so i´ll go ahead and give it a try, it´s just unnaturally big in size for the motherboard so if any knows of where to fine something more appropiate would be useful.

help with electronics - 16 years ago

Hi I am having a little problem with the capacitor on the motherboar, the instructions say to use a smoothing capacitor, but the only one i can find is 400v so don´t think this will be suited. Any body know where to find one or any way of improvising to get round the problem. thanks in advance.

Re: Mendel printed parts for sale - 16 years ago

Hi Jeremyl I used a product called Vinamold to make the mold, i have found it very well suited, you can reuse it by just melting it down. You need about six or seven kgs of it to make the full mold, so it takes quite a while to mell and pore it all, but the material is not expensive, if you live in the UK or Ireland here is a recommended supplier of it(on eBay). Any thing else let me know

Hi Kevin Below is a picture of the Mendel printer Made from these parts you were asking for. Haven´t got all the electronics in yet but all the plastic parts are there, i´m very happy with how they have performed so far. They are not perfect and the assembly dose take a bit more time and effort using cast parts instead of printed one, but the end result is pretty much the same, as far as i can t
