The redaction of this article is in progress thanks for your patience !

It will soon be describing the Lasercut plexyglass (PMMA/acrylic) RepRap "RePlex"

Design by Olivier Grossat & Eolipyle Association eoliyple.fr

WHY WE BELIEVE ACRYLIC IS NOT (definitly) AWFULL : When we started presenting this projet, many run yelling : "OMG ACRYLIC , CRAP !!" We'v been playing with acrylic for more than one year now and, if we first experimented the usual stuff with it (bend it : it breaks, constrain it too much : it cracks) we got increasing experience with this material and could use some simple techniques we'll detail further to avoid problems.

Not saying you can throw it against the wall/cat/with no damage (for both) but it's been printing for three month in a row at full speed and problems went (at least ) unnoticeable .

So please take time to give it a chance and give it a fair review.


We believe PMMA can be a great choice for beginners for some reasons :
-Easy and quick to "print" (the whole can be done in one hour depending on your lasercut speed)
-Not too expensive : usually around 150 $ for the plexy structure (some fablab /hackerspace lasercut for few)
-Homogenous : the material structure is plain

Still we recommend verifying the Lasercut laser beam perfect verticality on a small test (cutting a square, watch the edges must be perfectly vertical): if not the parts may not fit together.

FAQ :
-Q Why not Polycarbonate (PC) instead of PMMA ? (Yeeazzz : Bullet proof 3D Printer !)
-A Despite the fact i wouln't like to be shot, with or without a printer in my arms, it was a very common problem of price

Also for some reason the LaserCut we had access to didn't supported Polycarbonate cutting, please send us some news if you tried it ! (Also PMMA fumes are quite toxic, PC ones are worse but you already knew that didn't u ?)


A second review should be released in a few week/(month if too busy with other projects)

Working Notes. This is a stub!

Everything below this point is working notes. Here is a basic photo example, which is resized to 400 pixels wide, and on the left hand side of the screen.

This is 400 pixels wide, and on the left.

Here is the Mediawiki code to make that: [[Image:example.jpg|left|400px|This is 400 pixels wide, and on the left.]]

May contain scaffolding.
This page may contain "scaffolding" - mediawiki text from the Example page that may not need to be there. It may help to delete the parts that you don't need. (more details)

To insert a video from Vimeo, just insert the code below, and use the number after http://vimeo.com/ <videoflash type="vimeo">5202148</videoflash>

For Youtube you use the following format, you get the video's address by looking at the video in youtube, you need the part between the "=" and the "&" so this video has the address "youtube.com/watch?v=2FU0v-3gloo&feature=player_embedded", you need the bold part. Get it? <videoflash type="youtube">Hl4Gf5R4YJg</videoflash>
