  1. I was testing some unstable metals that are designed to dissolve over a few days in water/oil or in a few minutes in acid. They are mostly used in oil well operations where you can drop a ball and flow fluid down with to set or shift something the ball hits against. Once done you can simply leave the ball/sphere for a few days or a few minutes depending on the fluid around and it will dissolve/reduce, or be brought back up to the surface with flow. I printed the black stand for the ball with a side vent, but it ended up too violent and it just blew off the stand and didn't really do its job.
  2. Good to hear! I have also been having great success, been using/testing it all week with different mixes (basically my mix is thickening/drying up i keep using it ) . I am pleased so far . It cleans up nice, and a light wet clean/smear over resets the entire thing without really needing to add much more if at all
  3. Added update, I found that after I let the mix sit for a few days it made more of a syrup . I been using this consistency now with very good results. No water drop dots of sugar and more of a smooth covering when dried.
  4. So far I have used ABS, Nylon and PLA, Also used some rubber type filament. You will have to play with the mixture, I did about 50/50 mix of sugar/hotwater (Hot water near boil, from water cooler).. Then I put it on a warmed bed applying by dipping a paper towel in the mix. For me it made about the same coverage consistency as a glue stick, possibly even thinner/smoother.
  5. Needed to finish a print and was stuck at the office. I had minimal options but two sugar packs was one :-). I thought it was amusing then it worked well :-D How does the cube stick work?
  6. These machined metal spheres will dissolve most liquids. Acid, water and even air will break these down. The test shown in the video was in a 15% concentrate of acid. I was hoping the sphere would stay seated in the printed stand for the filming, but the ball took off with the violent reaction. Eventually gas attached to the sides and floated the plastic. You can even see the ball start to float from the creation of gas. The exothermic reaction created about 80C of heat.
  7. I usually use painters tape and or sometimes the glue / hairspray method to keep prints adhered to the bed. Well I didn't want to use the tape and I did not have any of the other two options. I do not know if this has been done before., but: I made a mix of sugar and water, approx 50/50 or near saturation where sugar crystals were completely dissolved. I then spread the sugary water with a paper towel over a warmed bed. The water evaporated leaving a nice washable very sticky surface. I printed some larger & smaller prints with ABS with good results. Update: I found that after I let t
  8. very nice , I really like the additional options/config
  9. I get random ones all the time. Same as what robertl said. With them I said they can translate the text, but link to youmagine for the source as I like to maintain control of the source files, for updates etc.
  10. Thanks If you want the nasa one to go both ways extrude a 1/4 square. Then print a square dowel that pushed through . I made a simple one like this which worked. But I wanted my design to be able to change if the ratchet area broke. So I needed it open and a way I could lock it in. So I simply made two ratchet sections that move independent . It was just a challenge for me to try to make a functioning mechanical tool back in August.
  11. I haven't tested the nasa one. But on inspecting the design. It seems they designed it to slip (click) over at around 3 inch pounds. I think it should be called a static non adjustable torque wrench . Where mine will not slip, as in most wrenches you push till she breaks . Note! I didn't print or test the nasa one. Please correct if I am wrong
  12. Well I've had the printer for about a year. I just moved to America. I shipped it. They destroyed it. But at least the Norwegian post honoured their insurance
  13. Did you give mine a try? If so how did it compare?
  14. Update. I ended up getting 2500nok for the damage. So like $400. Enough to buy and order new panels :-).
  15. Type this it works. Remove the two - on the ends. [-img]www-link[/img-] Example here, I used my iPad
  16. I haven't done a torque test, but I was able to put the same amount of force as a similar sized wrench. I would need to test to destruction to know for sure how many NM / FTlbs, but again that comes to how well it is printed I am in New Brunswick right now, when I get back to Houston, if I find the time I can try to break one
  17. Someone (sockles) went through the trouble of making a wooden holder for the ratchet wrench. Not bad but I think the wood is worth way more than the wrench
  18. Sorting has been a pain, but you can just set by upload order... other then that you can always set the main image
  19. I had the same thing if I used explorer. So I switched to Firefox, and or Chrome. I found those worked without issue. I usually never use explorer but got a new computer and didn't have time to install the others I had this issue a few weeks ago, maybe this is a new problem maybe not
  20. I found once it starts it is hard to stop it. Basically for me the knurled feeder would grind the plastic slightly causing eventual under extrusion. I found I could only print around 35mm/s without issue. I machined a new ptfe part and that fixed it for me. Then I updated the feeder and it only got faster and better .
  21. Test Print at 30mm/s. Looks like High friction in he Bowden tube if not the nozzle. I had similar issues and printing slower addressed this issue. After some mods and testing I was able to increase. 1 Do you have Roberts extruded? Maybe something to try if you don't already have it as pm_dude said. 2 inspect the Bowden tube for small dents or kinks or damage and the ends which can add friction. 3 is there grooves in the filament worn from the feeder? This is usually a sign of high friction.
  22. I'd be Major Tom on there and or Cleven sometimes Not gaming too much these days
  23. I trimmed mine. Took about 2cm off. No major issue. I did this as a time saver for when I need to order extra parts this way I can combine shipping
  24. I only did some initial testing. Mostly I don't use fine threads. I usually make a custom stub acme for what I need. I tend to just glue for my models and it gives a good representation.
