Cutting Rods

When we produce kits - to sell online or to prepare a workshop - we need to cut a lot of metal rods. Per printer it´s 14 cuts. For a series of 10 you know how many cuts we have to make. We always did it with a flex (angle grinder) out of the hand. The problem was that it was always slow, and after many cuts, when patience and concentration runs out, even dangerous.

To save time and our hands we made this quick construction.

Checking Straightness

While producing i3 3D printer kits we discovered that the linear rods are not always delivered nice and straight. This means that we have to check one by one if they're straight to deliver a good quality to our customers. We found out a simple and accurate method by letting the linear rods slowly role of a mirror. If it roles unevenly than it is not straight.This way unstraightness of around 0.2mm can be detected easily.

Having worked with the Prusa i3 for almost half a year now, we have many ideas about changing and improving it. In this video we explain our plans for pimping the printer.

Bothered with the closeness of basically all extruder types we designed an extruder that is as open as possible. I want to see - and I want to show - what the extruder does on the inside. Furthermore it should off course work properly and should be convenient to operate.

Perpendicular motion with rope

An interesting proof of concept as an alternative for moving the Z-bridge. Traditionally this has been solved by two (or even four in the deeper past) threaded rods that are driven simultaneously with a timing belt. This leads to somewhat difficult constructions.

New i3 Render

When we were making build manuals of the Prusa i3 printer in Blender, the temptation of making a nice render out of it was irresistible. Have a look at the result and wonder how we printed this Tux :)

Workshop march 2/3 in Berlin

4-printers

Here is a little fotostream from the worshop on march 2/3 in fablab-berlin.

There where 6 teams of 2 poeple each constructing there new reprap i3 3D printer. 
After two days of hard work installing software a new offspring of 6 i3 printers was born.

The engineers of Ford research and development now use open source 3D printers on their desk. 

One printer for every engineer to speed up workflow and enhance quality.

Xmas gifts with RepRap

10 December 2012

I just had a look on thingiverse to find some xmas gifts for this year.

One of my favorite where this nice 8bit pacman cookie cutter set. A perfect present for all members of the 8bit generation that are also in to cookies. 

If you got pirates in the family, take a look at the neet little Piratebay ship by zenix. It is definitely more difficult to print, but since everybody is scared of using the piratebay cause every shared file is somehow considered a copyright infringement ( read the comments on thingiverse under the Piratebay ship and you get my point ). You can make a stand and express your feelings toward openness and your open minded pirate friends.
