    Dissoluble Metal Ball Fixture.

    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. Eventually the amount of gas created just caused the ball to float. It did not effect the test, just made it difficult to film/document.

    Glass Bed Sugar Adhesion

    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

    Glass Bed Sugar Adhesion

    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.

    Glass Bed Sugar Adhesion

    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.

    Glass Bed Sugar Adhesion

    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 the mix sit for a few days it made a thick syrup like consistancy. I then used this on the warmed bed. The Sugar then solidified evenly and smoothly on the bed. I thought it should be shared as it could help someone in a bind one day .. Cheers, Cleven

    We made it, the New Cura

    very nice , I really like the additional options/config

    Asian Youmagine Clone?

    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.

    NASA does it, it's news ;)

    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.

    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

    do you print feeders in abs or pla?

    I did mine in Pla. Works fine no issue.

    careful when shipping :(

    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

    Did you give mine a try? If so how did it compare?

    Update. I ended up getting 2500nok for the damage. So like $400. Enough to buy and order new panels :-).
