They are pretty sturdy. The aim of the design is to get rid of the expensive T-Nuts and to use standard plates like in the picture below. The plates can be hand made from acrylic/aluminium/steel. The more holes you add to the the plates the stronger the structure will end up to be. The nuts and bolts will end up working like refits on an airplane where it gives extra strength to the light and tby BertFromProtoneer - New Zealand RepRap User Group
Yes... I have looked on Oooogle... but have not seen a lot. The Waxuum is an interesting take on it. Mmmm according to the book of Blogs everything is easy and works the first time... I will play around a bit more. Thanks for your input.by BertFromProtoneer - New Zealand RepRap User Group
I have used the filament I bought from Vik that he recommended. Nothing wrong with the filament... It actually very interesting because I made the plastic form and mold so warm that the plaster from Paris actually started glow in spots. It also started cracking all over. That's after I baked it in the over for a few hours to get moisture out. I wonder how wax would preform when printing bridgeby BertFromProtoneer - New Zealand RepRap User Group

Right... So what would prevent you from printing with Wax though? I heated the PLA + plaster to well over 400 degrees for over 30 min. My feeling is that it might be causing a vacume that keeps the running pla Inside. Will try a second casting hole to See if that would work.by BertFromProtoneer - New Zealand RepRap User Group
How hard do you think it would be to make a printer that would be able to print WAX? I have been playing with investment casting and did my first try at doing it with PLA today. Did not manage to get the PLA out so I just casted into what was left of it in the mould. Wax would make it so much easier to do castings. At the moment I would print it in plastic, make a silicon mold and make wax copby BertFromProtoneer - New Zealand RepRap User Group
My exact thought on the black extrusions to... It will make the other colours pop. I did not mention them before because they are still in the air but should arrive later next week. I have some samples of them and the do look nice. I was thinking that a multi-coloured head would be much easier with the bowden tube extruders.

Simon(wired1), looks like you are making some really good progress... Looking at the Ulitmakers, is the motor-less head not a better idea? Much lighter and faster. Less control I would think,but from what I can see it does not look like the quality is suffering. Jason(Inventive) also had an interesting idea. Would it possible to just Scale the original Mendel-Max parts down to 75% to fir Openby BertFromProtoneer - New Zealand RepRap User Group
Hi Jason... Sorry for the late reply. The black extrusions are $2 more expensive per meter.

Nice red printed parts. Did you get the filament from Vik at Dimondage? I bought some a while back and it was really good stuff. Any case good luck with the rest of the build.by BertFromProtoneer - New Zealand RepRap User Group

Hi there, did you end up getting your parts printed? I might be able to help if you still need it. Regards, Bertby BertFromProtoneer - New Zealand RepRap User Group
+1 for NZ Post. To be honest I did not expect it to arrive till after the long weekend,, Love your little printer Cam. Busy,busy,busy!!! I am still amazed by the printing process and will just sit there watching the printer do its thing.(Over and Over... ) Keep up the good work.

Hi INVENTIVE... Take your time. When you are ready to go let me know and I will cut+send. Regarding 123D and SketckUp you only need to know a few steps: Think of the part Draw the part Print the part Learn from the printed part Go back to step one Don't you just love it?!?!?!?

That looks good!!! I have subscribed to your blog as well... What I like about Openbeam is that its like Lego's for makers!!! You use standard link plates, 3D print links, laser cut perspex links , you can even CNC aluminium plates or plasma cut steel plates. The options are many. Now comes the fun part... Being creative!!!by BertFromProtoneer - New Zealand RepRap User Group
Thanks for the interest. Wired1 has already taken up the offer and I can help you and one more interested person.(3 projects in total) I can cut the extrusions or ship the full length for you. For me it is easier to ship the cut down extrusions but its up to you. Don't worry to much about the CAD skills it builds up as you make more stuff. I started out with very simple designs and I am now aby BertFromProtoneer - New Zealand RepRap User Group
Availability is not an issue... we have a good partnership with the manufacturer and if sales continue on as it is doing now we will be able to push the prices down even more.

Hi there, I recently bought some OpenBeam aluminium extrusions from Terence at Openbeamusa.com. Openbeam started as a Kickstarter project with the aim of making aluminium extrusions that take normal M3 nuts instead of the hugely expensive t-nut system that most extrusions use these days. (15x15mm anodized aluminium extrusion, made in the USA) Would anyone be interested in making a MendelMaxby BertFromProtoneer - New Zealand RepRap User Group
