i'm studying, but i know the life when work.. i'm working on a filament extruder too with a real endless screw designed with a compression profile for extrude a perfect filament from plastic pellet
Sorry I haven't been back thru in a while

Crazy life, work print work print work print.

Hoping to get on that soon. Right now I am working on a hand crank grinder and a filament extruder. Got to get some cheap plastic ;) I saw ABS lawn Chairs in crazy colors at Walmart for $18. About 2kg.
hy, the links you post are in manteniance, i think is great project, i'm going slowly because not much time to spend in the project, i'll wait forr see photos, thanks for sharing :D :D

Instructions

the structure will be like mendelmax mendelmax.com/tikiwiki/tiki-index.php?page=MendelMax

kickstarter.com/projects/openrail/openrail-open-source-linear-bearing-system

docs.google.com/spreadsheet/ccc?key=0Ao-fptzJAVfGdDdnd3htckhZUVdWUTdvRnJQUE JrMUE&hl=en_US#gid=0

the weight of single part 2x2x11cm is 20g with 3 perimeters and 80% infill and take about a our to complete (75mm/s)

with this settings the total weight of all plastic extrusion for mendelmax are 900g (about 17€)

for make a complete bar we need 3 pieces (60g of PLA) and 8 pins for joints

according to this docs.google.com/spreadsheet/ccc?key=0Ao-fptzJAVfGdDdnd3htckhZUVdWUTdvRnJQUE JrMUE&hl=en_US#gid=0 i have made different type of extrusions, 4x 105mm = 420mm extrusion and so on :)
Hi, its been awhile since you posted so was just wondering how your progress was going. I am working on a similar project and figured I would share with you how I am tackling this. I want to print structural tubes for building frames with like pvc pipe green house frames but with the strength that can be done by controlling the internal structure inside the pipe. I am going for 16"-48" lengths. I see the benefit of your track rail set up for attachment points. I did a quick sketchup mock up of how I intend to modify a prussa to the task.

I post my ideas at a board I am trying to spread reprap awareness on have a look at the 9th post for the sketch up screen caps. forums.adamvstheman.com/viewtopic.php?p=26949#p26949

Really a challenging project !!
replace fasteners is possible but you have to change the design solutions. prefer clips instead of screww/nuts, issue of clip is that needs accurate dimensions. I'll follow your project for sure !
thanks a lot :) .. if i use clips in all structure and some threadlocker for  fix i think the result will be very strong structure ;)
I would also add a printed rod (tight fit) + glue going through the center hole in both "extrusions" at each joint. That should seriously increase the stiffness of each connection. Awesome project. I'll definitely start watching this.
yes is a way to increase streight of joint, i'm making some tests, one include to heat surfaces and put togheter :)
How are you gonna do the fasteners?
i'm thinking it, i'm evaluating the possibility to do some pieces wich need to be melt to fiz the structure.. i'll make some try
Beautiful as I was going to make some extrusion aluminum parts too but now I don't need to though I wonder how strong it is.
to make a stongs extrusion you must set (with PLA) the temperature to 190°C if print one, without fans, 205°C if print 2 extrusion at some time about 3mm near one from each :) the 10cm one i can't broke with hands
WOW, well I can't see how you put them together to make a longer one but I can see any interlocking parts or is this just like the real Aluminum ones where each piece is attached by a small tab with a screw?
it can be attached with a plastic T tab and screw, but i will use clips to put all togheter, the longer one witch u see in the photo is made by 3 pieces locked with 4 T clips, can be attached by melting the first layer too (like uppen in the printing ptocess)
Awesome, I've been meaning to try this but my printer has been occupied with making Prusa parts. Very excited to see the results.
i'm prototiping now :) when i dont make prusa parts i print some pieces for this project ;)
