Casting Aluminum for the Home from a Simple 3D Print

  • Returning to the foundry, I cast an aluminum wall hook. The design of the hook had to take into consideration how it would be cast. Every face had to taper perfectly for the pattern to actually release from the mold!

    Christ man, you really didn't have to make an entire demonstration for why single-pull casted parts need tapering and drafting but the fact that you did just shows how incredible you are as a person. Cheers to that

      I don't know. Those are the sorts of simple mistakes probably a majority of interested amateurs make and curse the heavens over. It's nice to have a video targeted to people nee to the idea of casting being given a solid practical explanation of just how important that step is.

      [He] who made for you the earth a bed [spread out] and the sky a ceiling and sent down from the sky, rain and brought forth thereby fruits as provision for you. So do not attribute to Allah equals while you know [that there is nothing similar to Him]. ( 2:22 )
      And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah the like thereof and call upon your witnesses other than Allah, if you should be truthful. ( 2:23 )
      But if you do not - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers.( 2:24 )
      And give good tidings to those who believe and do righteous deeds that they will have gardens [in Paradise] beneath which rivers flow. Whenever they are provided with a provision of fruit therefrom, they will say, "This is what we were provided with before." And it is given to them in likeness. And they will have therein purified spouses, and they will abide therein eternally. ( 2:25 )

    Forgive me if someone else has already commented this, but depending on the material you 3D print with you can use acetone to smooth the surface instead of doing all that sanding. For parts such as this where it's mainly aesthetic and there's no real tolerances required, it would be ideal and save you a fair bit of time. Nice work!

    i've worked in a bronze sculptor's foundry, on wax models through to the finished life sized pieces, a small crew pouring glass into moulds and have done some lost wax and cuttlefish casting for small metal objects.
    awhile back, i was noodling around with 3d applications/models and renderings...now, i am about 10 months in with 3d printing...it's very VERY satisfying to finally hold in my hand that which was only viewable...on a computer screen.

    Here is a tip for you, instead of using super glue to generate a smooth surface on the 3D printed part, use UV light curing resin instead. It makes for a super smooth finish that only needs light sanding and produces an extremely nice finish that wont transfer artifacts.

  • @tonybrock5288
    @tonybrock5288 2 ปีที่แล้ว +4

    Why bother producing a perfectly polished 3d printed part when the finish of the casting is so rough? Rather do the polishing on the finished part. I suspect also that the lack of tamping and a coarse sand is also an issue affecting the finish.

    • @sidekickbob7227
      @sidekickbob7227 2 ปีที่แล้ว +5

      For what it is worth; The smooth surface of the printed part is done for achieving a clean release between the plug and the sand mold. He did not press the sand that hard, because he wanted it to act as an air vent all over the surface. If he had made the mold in a material that didn't provide such good venting, he would have to make venting gates. (With his orientation of the cavity, he would need a vent at each finger. He could turn it upside down with the sprue on the other half, and manage with one single vent, but I'm sure he had his reason for the way he did it) . Anyway, whatever of method, he would have to polish the part afterwards. Removing the first rough surface goes quickly. It's the finer grid who takes most time and effort, and that work will be the same at each method.

    • @Sparky666
      @Sparky666 2 ปีที่แล้ว

      I allways use a strainer for the first layer of sand. And i use long cocktail sticks to make small air vents. It will save you a lot of time finishing the cast. And i de-gas and flux the aluminum just before casting.
