Sometimes traditional 3D printing just doesn’t cut it - that’s where the Mark Two from Markforged comes in! Using continuous fiber inlays together with high-performance Nylons, it creates parts that can compete with metal. Too good to be true?
For 13.5K USD I can get a machine shop to make me a lot real metal parts!
True, but those typically have a lot longer turnaround times and are more limited in their geometry.
Is there any work on doing a reprap variant of the continuios fiber system in progress? Someone has to be playing with it? Is there any schematic of how they do it?
@Markus_Granberg the patents are public, but there’s clearly been a lot or RnD for getting the process and the materials right.
@funinthefalls
I would like to see how you’ll machine the shapes a 3D printer can produce 
This is an interesting read about a different approach, presumably not covered by patents. An university project, initiated by a really smart Dutch guy, some of you might already know Joris van Tubergen

@Markus_Seidt This is very interesting, hopefully they will publish their findings. Coincidentally I have an unused 2kg spool of aramid fibers at home.
@ChPech As far as I know the project, which is kind of a proof of concept, is finished and they published all their findings. I’ll ask Joris if there are further plans.
That would be great, thanks.
Wow! That’so awesome!
Another interesting approach

@Markus_Seidt interesting approach. In its current state they obvsiously had some challenges keeping the fiber in the extruded material hence the putty knife. It would be difficult to print a lot things without a fiber cutting mechanism. That would impact their fiber winding and ebmedding system. Cool stuff though.
Ich hoffe nicht zu aufdringlich zu sein, aber ist der Mark Two schon wieder zurück verschickt worden oder hast du ihn noch zu deiner Verfügung?
Wir haben da in unserer Firma so ein Problem mit Metallpartikeln auf Isolierteilen und ich habe schon einige Sachen ausprobiert um Werkzeuge/Hilfsmittel aus Plastik herzustellen und bin vor kurzem auf Alloy 910 gestoßen. Damit waren gute mechanisch belastbare Teile möglich.
Aber es geht sicher auch besser 
Zu meiner unverschämten Frage… könntest du dir dieses Modell -> http://www.thingiverse.com/thing:2084967 mal ansehen und durch deren Slicer laufen lassen. Würde überhaupt ein inlay möglich sein?
MfG
PS. 100€ wenn du mir eine Carbon verstärkte Nuss zukommen lässt, damit ich meine Chefs für einen neuen Drucker erwärmen kann
@Igor_B_Thorvinus sorry, der Drucker ist schon wieder zurück, aber du kannst gerne bei http://mark3d.de anfragen
Werd ich dann wohl machen müssen (love marketing people, not )
Keep the good work, love all your videos
@Igor_B_Thorvinus och, die beißen nicht
