Hello all! This is my first post and i am very excited to begin my quest for my very own 3d printer! I have read about the RepRap however i have one nagging question (or fear that is)... How durable are the parts created by the reprap machine? I have seen some close up images that show a distinctively "dotted" makeup of the parts created by this machine. This makes me wonder how well fused the polymer is and how such parts will react to stress. I would sure like to hold a part created with this machine in my hand and then subject it to all sorts of destructive tests with my trusty assortment of hammers :). So finally i ask a real question or two... 1. How well fused is the thermoplastic parts made by this machine? OR 2. How can i get a part made by a reprap machine sent to me so i can destroy it... opps i meant "test it"?

Good enough to make a 3D printer from them. :D

2. How can i get a part made by a reprap machine sent to me so i can destroy it... opps i meant "test it"?
a local reprap user group is the best way.

The simple answer is you have *some* control over the strength based on changing infill patterns, changing the infill density, and rotating the part to make the best use of the part's anisotropic strength. IE: if you load the part so that you are putting tension along the Z axis, the laminations will tend to separate, which makes it weaker in this direction. If you load it on the x or y axis, it will be stronger. I get the feeling that repraped parts will always be noticeably weaker than a part from a commercial molder, but you can probably adjust your print settings to get close.]]> dazed.dnc General Thu, 16 Dec 2010 00:33:48 -0500 https://reprap.org/forum/read.php?1,68489,68490#msg-68490 https://reprap.org/forum/read.php?1,68489,68490#msg-68490 An Original Name General Thu, 16 Dec 2010 00:28:33 -0500 https://reprap.org/forum/read.php?1,68489,68489#msg-68489 https://reprap.org/forum/read.php?1,68489,68489#msg-68489
