Imprimante 3D Prusa i3 MK4

The 3D printer from Markforged is the first of its kind, using the new CFR technology: Continuous Fiber Reinforcement. This method, based on FDM printing, makes it possible to add, inside the printed part, continuous fibres (carbon, glass or Kevlar), which can be extruded with the help of a nozzle and thus fused with the part, giving it tenfold strength in addition to other properties, depending on the type of fibre chosen. The reinforcement strategy (number of lines, layers, orientation, etc.) can be chosen according to loading conditions.

The base material is either nylon or “Onyx”, a nylon filled with carbon micro-fibres. Onyx, when used alone, is five times stronger than ABS. With the addition of fibre reinforcement, it can offer the strength of aluminium.

Features 
Printing volume: 32 x 13.2 x 15.4 cm
Layer thickness: from 0.1 to 0.2 mm
Very good dimensional stability
High strength

Rates

*Optional – The volume of fibre reinforcement required is calculated when preparing the print files.

Only the first 15 / 30 minutes will be charged at the time of booking. The balance can be paid on site.

The 3D printing technology used at Fablab Descartes is FDM (Fused Deposition Modelling).
This technique consists in melting a filament of synthetic material, usually ABS (Acrylonitrile Butadiene Styrene) or PLA (Polyactic Acid) type plastic through a nozzle. A small wire of molten plastic with a diameter of about a tenth of a millimetre is deposited and forms the different layers of the 3D model.
In order to use these machines you must come with a 3D model created with CAD software (Solidworks, Blender, Freecad, Fusion360, Onshape, etc.) in .stl or .obj format.
You can also take part in one of our training courses or come and practice at Fablab to create your 3D model.
You will then have to pass your file through the slicer of the machine in question (Simplify3D, Cura or Slic3r) to generate the Gcode which will be interpreted by the machine.

Machines and features
All our 3D printers have a heated platen to improve the hold of the part on its support.
