These settings were used to ensure adequate adhesion of the first layer to the print bed, consistent extrusion of ink, and slight overlap between consecutive layers for each printed sample. For cast samples, the blended resin was cast onto a Teflon sheet using a metal mold to get a ...
dirt and other surface contaminants. The washed mass was dried in sunlight under the cover of the white cotton sheet (making air gap of at least 4 cm between mass and sheet) for about 2 days and then in an oven at about 95 °C for 24 h. The dried material was crushed into ...
All safety precautions that are generally observed when working with an axe or a hand saw also apply to the operation of pole pruners. However, because a pole pruner is a high-speed, fast-cutting power tool with a very long reach, special safety precautions must be observed to reduce the...
