    Dimensioning and tolerancing close fitting mating parts

    I agree with the advice of jjjaos, but with one exception. You need to consider the length of your parts. If your mill bed can handle a 3 foot part, great, but if more than one set-up is required, I would add a little more to the "fit". Talk to your machinist. He/she will give you...

    DIMINSION ROUNDING

    The type of material that I was thinking of is polypropelene. The plastic needs to be flexible, but yet tough. My prototype is made out of acrylic tube. The wall thickness is .1 inch. Surprisingly the prototype has lasted 3+ years of use. But acrylic is brittle when hit just right.

    3D Shading + Plotting

    In a nutshell: under "render" select your desired material from the materials library, select and place your 3 light sources (just like in a photo shoot), set the values for your desired shading and shadowing effects. Render and save the rendered file into bmp, jpg or other. (I use...

    centrifugal vs injection vs blow molds?

    I have a product that is to be molded. Basically a long hollow tubular shape with details on either end. Total material volume per shot is less than 25 cubic inches. Which would be better price/product wise; a two piece family mold (which entails a sonic welder for assembly), a blow mold...
