Maybe a mixing structure like those used for two component syringe dispensers (like ) can be replicated in metal, maybe by milling. Like the cylindrical part of the hotend above the nozzle replaced by two half shells with a milled rectangular labyrinth pattern inside. Basically it forces the fluid to fold onto itself for several times thus give a decent mxing without active stirring. It may beby dronus - Developers
There are some printers that print plastic coated metal powder by laser sintering, followed by evaporation of plastic and metal sintering in an oven. This concept should work with a RepRap too. However, someone would have to develop a well working metal loaded filament. And a steel nozzle would be needed i think, otherwise it would be grinded by the metal particles. The object is then printed aby dronus - Developers
I am not sure if I understand exactly what you mean, but I think your idea is to have a much larger hot area around the actual nozzle hole. Is that right? The idea maybe is, that the printed material is swept flat or away so that it is more evenly spread in the print layer. However, that would not give better quality I think. In fact, the material swept away has to go somewhere. Ideally, for 10by dronus - Developers
I think one extruder mixing several materials would not be very useful. The current extruder designs store quite an amount of material inside the hot region, and some of it stays there for quite a long time. This is most easily observed when changing from ABS to clear PLA filament, where it usually takes about 50mm filament run until the last foggy shades of the ABS vanishes.

So the new slicer is part of the goal: To have a standalone reprap machine that can be used from any computer in the room via a web browser so anybody could run a print from his own desktop with no further requirements than to plug the printer's mains and ethernet cable or do some wifi setup.by dronus - Developers
Actually, VisPrinter, a web UI in progress, will give this option too. VisPrinter will exhibit it's Slic3r to other VisPrinter running machines, thus enable remote slicing. However, VisPrinter is meant as an easy replacement for Pronterface, so it installation should not necceseraly include the installation of a separate remote slicing server the user needs access to. Also I cannot provide a deby dronus - Developers
I totally agree that enhancing Slic3r would be useful for the community, but I think that my goals are useful either and I am unsure if I can reach them in reasonable time by enhancing Slic3r. I already studied Slic3r for some time before deciding to begin something new, and indentified some obstacles that I thought I would not be able to take out in the spare times I have for work on this.

Hi again, i've made some promising experiments towards remaking a fast GUI-less variant of Slic3r. The reason for this remake is the low performance of Slic3r on embedded platforms like the RaspberryPi that performs 30 times slower than today PC computers. I like to have a cheap embedded platform capable of quick slicing attached to the printer. Remake means that one day it should implement moby dronus - Developers
My experimental Vis/Printer printer interface server mentioned in this forum runs on the Raspberry Pi too. It can also be viewed on the pie's browser, except for the 3d preview. However, it is not very useful as long as there is no running Slic3r on the raspberry. As the RPi would be somehow slow on slicing, I'm planning to add remote slicing on more powerful machines. I'm also planning to dby dronus - Developers
This runs as a standalone server for now. I like it that way because it could be easily run on a local machine without large dependencies (the Slic3r has some huge heap of dependencies if the premade binaries do not fit however) and there are much less headaching configurable things that could interfere. However, it should be no problem to set up a small proxy in your WWW server if you like toby dronus - Experimental
Adding video depends on the PC used as server. The RaspberryPi would need an elaborate software stack to do video compression by hardware, otherwise it would be to slow. However, if a full fledged compact linux PC would be added to the printer, it would be no problem to attach a webcam, run VLC or some other tool to provide a http stream of it and embed it as HTML5 or Flash video to the HTMLby dronus - Developers
(Sorry for posting again, fits well better here) VisPrinter is a early experimental web interface on top of pronsole replacing Pronterface. It is meant to provide a full UI for a RepRap machine to any browser. So anyone in a workshop can print from its own desktop without having to install the Printrun/Slic3r toolchain and serial drivers. It can be downloaded here: README: Benefits: - Priby dronus - Developers

Hi, da ich ziemlich genervt war weil Slic3r doch recht pingelig ist und man mit Rhino, Blender, und selbst OpenSCAD täglich non-manifolds erzeugt, hab ich vor ein paar Tagen einen kleinen Modeller improvisiert, der jetzt schon ganz gut funktioniert, wenn auch sehr gewöhnungsbedürftig. Leider schafft auch er non-manifolds herzustellen laut Slic3r, das Problem steckt im System wie es scheint :-) aby dronus - Software
