Sounds like an overkill to me. The Laser & the Pump alone would cost a fortune. How would you maintain the vacuum if the molten metal needs to be extruded? And if you are using a magnetic field with high magnitude you could skip the laser & the pump and go straight to induction heating and materials which can withstand the temperature. (almost all ceramics do that and there are plenty ofby ElectricMucus - Mechanics
Looks like fun, I can't imagine it could be used for anything useful though. At least in this state of development, the frame oscillates way too much to do anything productive. Change it from 1/9 scale to 1/5, use steppers instead of servos and a more rigid construction and it would be fine. And this software will probably cost more than an army of those miniature robotsby ElectricMucus - Robots!
I think there is a very strong point for induction heating: You could make the hot zone very, very tiny. Right now the major part of the heat does not go to the filament but is lost from dissipation and infrared from the hot end, the heater block etc... A induction heated hot-end could consist only of a tiny ring or mesh of iron or high permeability steel with ceramic for the rest. The plastic wby ElectricMucus - Plastic Extruder Working Group

Hello, well the problem with ramps is, I want some additional means of controlling the dc motor of the tool. So another solution + ramps would be expensive It would be nice if the rpm could be controlled by software and I have no Idea how I could do this with ramps. I assumed that there would be a ramps equivalent for mills, but as it seems I was wrong...by ElectricMucus - CNC Routers, Mills, and Hybrid RepRapping
I've bought a CNC mill on eBay as well as a Arduino 2560 Clone. Now I am looking for other things I need. I have though of RAMPS but a kit is expensive, it has options I wouldn't need & is missing something else. At best I would have 3 stepper outputs & one high powered dc output for the tool. I wonder if there is a shield for that or a similarly continent solution...by ElectricMucus - CNC Routers, Mills, and Hybrid RepRapping

I think if you go this far - meaning heating with induction and powder extrusion you should attempt to make it usable for copper as well. It isn't that far you basically only have to make the frequency of the induction coil adjustable as well. Induction heating works with theoretically any material iron is just the easiest to do because you get the benefit of magnetic hysteresis in addition to tby ElectricMucus - Wire and Thread Embedded Extrusion

I just had an Idea of making a Magazine. Every Issue would describe some part of a reprap and would include some part you need. Issue one could include an extruder, printed and nonprinted parts with an intro and general concept of reprap.

Several People have reported that they have more stringing and ooze on 1.75mm than on 3mm filaments. What is behind this? For example there are some makerbot users having issues... Is that more a issue due to unoptimzied software / the makerbot hardware or is there a principal disadvantage which leads to reversal not working as well?

I think you could get fairly accurate results with a acceleration sensor and gps. Of course this doesn't work for existing photographs. The better way is a second camera though. But there is nothing against combining the 2 since a position wouldn't hurt anyway since otherwise the error can accumulate .by ElectricMucus - 3D Scanners, Book Scanners, and Optics

On the other hand this could work... This might be sufficient but you'd have to restrict the replication process to other parts... The second generation could use this... which also has the advantage of being able to produce low res parts and use the same powder.by ElectricMucus - MetalicaRap

Awesome Idea! How about using a metal spray paint to increase the reflectivity of the material? I think the highest gain could be archived using a parabolic or semi parabolic form with the emitter sticking out of the center. Should look like one of these radar antennas then. You could also employ a secondary smaller reflector on the other end which reflects onto the larger dish to increase thby ElectricMucus - Let's design something! (I've got an idea ...)
Big inkjets or Plotters normally take rolls of paper and print on the end while rolling it out. Most also have a integrated knife for cutting the sheet after print. You could use the x axis for the print head and y for the rollers but no way this can be changed into a 3d printer later on.

Quote3mm ABS is very reliable. How can Plastic be reliable? My point is: if the extrusion mechanism, the metal part of the extruder is made for a smaller diameter I will get no grip, and if the hot end diameter is too narrow this would cause problems as well. So I just want to know if this could be the case... PS: Why do I get these 'weird' responses when buying a kit / not actually buildingby ElectricMucus - General
Can someone tell me please what exactly "optimized for 1.75mm" means. Well it should be fairly obvious but how reliable can I print with 3mm filament? It's the Orca v0.2 Mendel variant.

I don't think any standard pressure cooker would be large enough for any usable machine. From what I've researched building High Vacuum Chambers is a high tech art unobtainable by almost any technique.
