My Prusa repstrap ( mainly of ply ) build is coming along nicely and I was wondering if anyone knows how much in kgs or length of abs or pla is needed to build all the rp parts needed to build another prusa. I was thinking of ordering a sample pack of pla that includes 5 rolls of 20 meter lengths of different colors. Would 20 meters be enough to print all the parts? It might be the first rainbow prusa!!B)- I know this depends on infill ratio and extruder nozzle size but a general idea will give me somewhere to start. Also i will be building my own hotend and can't find a source of ptfe in Australia. https://reprap.org/forum/read.php?4,125922,125922#msg-125922 Sat, 11 Jul 2026 01:23:47 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,125922,126696#msg-126696 https://reprap.org/forum/read.php?4,125922,126696#msg-126696
My design is under Simplified Ball Bearing Mendel. Please print and enjoy...

It will be interesting to find out how well it works if at all.

The basics are there, triangular frame, threaded bar, stainless bar for the slides, linear bearings, etc but the devil will be in the detail.

I am at the stage of making the hot end and would like feedback on my final choice of Wildseyed simple hot end.

The items i am having trouble sourcing locally in Australia are the Ptfe rod and Kapton tape.

I decided on this because I have lots of welding tips on hand and the assembly looks simple enough.]]> gregted Reprappers Thu, 29 Mar 2012 08:02:28 -0400 https://reprap.org/forum/read.php?4,125922,126422#msg-126422 https://reprap.org/forum/read.php?4,125922,126422#msg-126422 -------------------------------------------------------

Just a thought - if you haven't actually done any printing yet, you will probably find that you chew up quite a lot of filament just getting your machine calibrated and printing well enough to start making "real" parts like your next RepRap, and then you will probably discover that each different type of filament you try is just a little bit different to the last (presumably due to subtly different melting points, different quality of "self-adhesion", etc), so the settings that work beautifully on your first colour filament produce a real dog's breakfast with the next colour.

I would suggest that you buy at least one longer roll (say 1 kg) of one colour, sufficient to print the whole job, and plan on printing your RepRap in one colour only. If you are luckier than me, and get everything working perfectly very early on, go for the rainbow version - but be prepared for some failed prints the first time you try a new colour.]]> julianh72 Reprappers Thu, 29 Mar 2012 02:13:52 -0400 https://reprap.org/forum/read.php?4,125922,126398#msg-126398 https://reprap.org/forum/read.php?4,125922,126398#msg-126398 -------------------------------------------------------

I found it to be not very accurate at the length used but I did use it to get a ballpark figure for costing out prints, the time scale it outputs is way out too, unless it's been fixed in the later versions. I still live in the dark ages and use SF41 as my settings work very well]]> NelsonRap Reprappers Wed, 28 Mar 2012 18:23:39 -0400 https://reprap.org/forum/read.php?4,125922,126370#msg-126370 https://reprap.org/forum/read.php?4,125922,126370#msg-126370 ikilledkenny Reprappers Wed, 28 Mar 2012 15:36:36 -0400 https://reprap.org/forum/read.php?4,125922,126293#msg-126293 https://reprap.org/forum/read.php?4,125922,126293#msg-126293
I searched for the multicolored hot end but no luck.

They can only mix a stripped grey at this time. Sorry I lost the link.

Sooo, I should be able to print out a set with 3, 20 meter rolls but in 3 colors. Interesting.

I am interested in printing in multiple colors. Is there a way to do this without manually changing the input.

j andberg, do you have any links to your design.]]> gregted Reprappers Tue, 27 Mar 2012 06:42:02 -0400 https://reprap.org/forum/read.php?4,125922,126005#msg-126005 https://reprap.org/forum/read.php?4,125922,126005#msg-126005 NelsonRap Reprappers Mon, 26 Mar 2012 15:26:40 -0400 https://reprap.org/forum/read.php?4,125922,125940#msg-125940 https://reprap.org/forum/read.php?4,125922,125940#msg-125940
My design (Simplified Ball Bearing Mendel) uses a bit less than 1.5lb (about 0.65kg) at 25% infill density.

20 meters isn't enough, I'd say you'd need 50 to 60 (you're talking about 3mm diameter filament, right ?)]]> DeuxVis Reprappers Mon, 26 Mar 2012 08:26:08 -0400 https://reprap.org/forum/read.php?4,125922,125922#msg-125922 https://reprap.org/forum/read.php?4,125922,125922#msg-125922
