QuoteGreg Frost I have never liked the idea of battery powered vacuuming. What about the idea of the vacuum having a spool of electrical cord that it plays out as it moves away from its starting position. And reels it in as it moves closer. Then you could have a properly powered vacuum instead of something that only works well on hard floors. I have a Roomba and a Neato robotic floor vacums andby jb92563 - Let's design something!

I have used the Cyano/bicarb technique for fixing stone dents in wood propellors and there is the issue of wicking effect and the liquids own film strength. A micro drip from a tiny syringe quickly spreads out in the bicarb to ~5 times the original drips diameter. Smaller drips are hard to make because of surface tension. I think you would have to thin the cyano and use somewhat moist bicarb sby jb92563 - Let's design something! (I've got an idea ...)
I am also having that same problem with my ord bot Hadron. it uses threaded rods on the Z so I know there is no slipping. Im also using the latest slic3r version. I'll check the gcode as well to see if it is commanding the z to come back down far enough at the perimeter printing.by jb92563 - Reprappers
This is great stuff your doing but I'm curious how you handle the two conflicting requirements of: 1) The cement needs to be fast setting so you can build up layers taller without collapsing the earlier layers because they have not set yet. 2) The cement should have enough working time so that it can move through the extruder without altering the flow rate or blocking up the extruder pasaby jb92563 - General
You may be on to something. How about P3P = Personal 3D Printer or C3P = Consumer 3D Printer ... and early forrunner of C-3PO Droidby jb92563 - General
OMG, just assume that everything discussed will kill you unless proper precautions are taken. Substitute the words "Deadly Poison" for every chemical mentioned in the posts above and proceed as you see fit. If you can't figure out WHAT precautions to take then don't even consider it. If you don't know what an MSDS is or where to find one then stick to baby safe consumer products from the marby jb92563 - General
A discussion of enclosures for a 3D Printer got me thinking of the nature of 3D Printers in general. To my mind a 3D Printer is much like a toaster but without the food theme. Its a new type of appliance that belongs on the counter top or out in the open as opposed to sitting in a box in the garage or down in the basement. With that in mind I was thinking of where it could live in a persons hoby jb92563 - General
Should developers be able to collaborate towards a common goal rather than causing multiple simultaneous developers to RACE so they can claim the solution first. If I was a developer I would not want to do a lot of work only to find that another developer has thrown something together quickly just to claim the bounty early and make all my time a waste even though I had a better solution.by jb92563 - General
I am wondering why the Europeans are having a considerably highter adoption rate of 3D printing vs North America? Is it promotion, creativity, philosophy differences? I'm from the US and 2 Months ago I knew very little about 3D printing and had only heard about it a year or so ago through watching a show that Jay Leno had been using this technology to make replacement parts for his rare cars.by jb92563 - General
Nice work Rapcraft. Since with vertical windmills are blades are better supported you probably have a better application for 3D Printed foils than the Conventional Propelloer type windmills. I wonder if a variable pitch mechanism on the blades might help optimize output and help get it started in lower wind speeds. You could vary the pitch based on RPM.by jb92563 - General
QuoteZerker I always thought the root of the blade, was where it attached to the hub, if so the above design would not help aleviate the problem of PLA not being strong enough to endure the Thrust force at the root. I propossed that the PLA is for the ribs and skin only, and that the Spar which takes all the loading is a Carbon or Aluminum tube which can handle the loads etc. The spar is the paby jb92563 - General
If you need to use a 3D printer to make a wing of PLA and ABS then since we already know the material is not strong enough on its own, you will have to use the old style balsa wood model technique of wing construction. You can make incredibly strong and light wings this way out of relatively weak material. The process would be to 3D print a lot of ribs, and glue say every 3cm on to a rod sparby jb92563 - General
