How To Make Your Own Sugru Substitute

pic2 shows a 2"x2"x2" solid silicone cube that cured enough in two hours to be removed from its plastic box form. For years I have been looking for an inexpensive way to create a flexible skin covering for robots and electronic circuits. I have tried several kinds of casting urethane rubber and silicone rubber. They all have their difficulties and either set up to fast or too slow. I and many others have tried using the inexpensive silicone caulk that is readily available from hardware stores. So I wanted to add a catalyst that would help the silicone to cure from the inside out rather than just from the outside in. As I understand it, 100% silicone caulk works by the moisture in the air initiating the polymerization of the silicone. I experimented with quite a few additives to try and introduce some moisture into the uncured silicone. It turns out that corn starch is highly absorbent and when sitting around in an open box it will absorb moisture from the air. So that's it.

7 choses à fixer ou à faire avec les Oogoo Oogoo is a mix of 100% silicone caulk and corn starch. The corn starch evenly distributes moisture which it has absorbed from the air. This helps to activate the polymerization of the silicone in a controlled way. So, unlike regular caulk which can take days to set up, Oogoo can set up in an hour or two no matter how thick it is cast. Materials For these projects you only need a few materials: Puffed Rice Corn starch 100% silicone caulk-the type that smells like vinegar and has no acrylic or latex additives. plastic cups plastic bag Nitrile gloves 1/16" and 1/8" thick plastic sheet material. Spray Lacquer from hardware store. Naphtha or Turpentine solvent from hardware store Artists oil paint (optional) The Standard Oogoo Mix The standard mix of Oogoo consists of 2 silicone caulk to 1 corn starch by volume. WARNING: While mixing, Oogoo will give off the strong smell of Acetic acid which can be irritating to the eyes and respiratory system.

Tag - fraiseuse - DIY Planet : Made in Fr Le tendeur en S dont j’avais évoqué l’idée dans le post précédent est maintenant réalisé. Il fonctionne à merveille Les pièces du tendeur Tendeur en place J’ai eu ensuite quelques déboires avec les axes X et Y. J’ai donc usiné des nouveaux supports pour y insérer des roulements à billes de rollers à la place des paliers. Roulements Pour les chariots, j’ai remplacé le double palier par une douille à billes prisonnière à l’intérieur du chariot. Douille à billes Après ces quelques modifications, tout fonctionne parfaitement ! Reste à réaliser le support de la tête d’impression… Ce n’est pas une mince affaire, la pièce est relativement complexe, et j’ai du mal à la visualiser et surtout à en estimer les mesures exactes. Heureusement, l’ordinateur est là pour nous aider à simuler différents modèles de support. Le premier « truc » qui vous vient à l’idée: SolidWorks ! Espace de travail Mon choix s’est donc porté sur Openscad. Openscad dispose d’un éditeur intégré mais celui-ci est peu évolué. Option
