Ultimaker 2 Dual extruder upgrade - Creatr XLabs

Recommended Posts

Hmm... to radically change the design UM2 not make sense. If I understand correctly the cause of the problem, the full multi-nozzle printing is only possible when changing the type of material used, which leads to changes in the feed mechanism and, accordingly, in the code, which will have little to do with the code UM2. In essence, it is a new model of printer ))

I dug up one of the Stratasys patents for support material (http://www.polychemistry.com/aquazol/

 

Furthermore, PEO is not as hygroscopic compared to other commercial Water soluble polymers including polyvinyl alcohol and polyethylene oxide, and thus PEO possess significantly greater dimensional stability in ambient humid atmosphere compared to these other polymers. Moreover, PEO can be extruded at higher temperatures Without decom posing and having its melt viscosity change With time.

 

They probably have innovated further since then as this patent application is 15 years old now, Stratasys SR-30 that the Uprint are using is described in the MSDS as "Terpolymer of Methacrylic Acid, Styrene and Butylacrylate"

All nice, but still no second nozzle on the Ultimaker. Does anyone know when the experiment with the Utimaker Original will lead to a definite product for the UM2?

Most probably never. The way the dual extrusion was designed for the UMO should have been used for the UM2 more or less the same way. It didn't work as we all know. A proper dual or multiextrusion will have to be implemented in a different way. Please also check the forum for posts on foehnsturms development on dual head extrusion and Ultiarjans transformation of it to the UM2.

I'll be at the Ulti Evening in Utrecht (NL) monday the 15th (99% sure) to demonstrate my UM2 dual head setup. The main topic is the new CURA, but there will be plenty of time to ask questions on this later on in the evening.

And yes it does work very well, I'll try to post a few new pictures this weekend.

hi i can not find the page were i can buy the head for um2

there is nothing to buy... the guy who started this thread is teasing since 2014... but there is no product.... no video ... basically no proof of anything...

There are experimental dual UM2's, this one is the most promising IMHO;

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
