Learn ShapeJS: Coins

by • April 18, 2016 • No Comments

On tap for this week we will print our own coinage. Don’t tell me you haven’t secretly wanted your own currency! When we initially added
cast metals it was one of the initially projects I idea of. Here are the initially tests I’d did:


These came out well, advantageous and so I quite
expected. The additional detail was incredible
, really great mass
to them and they sounded right when you flipped them. If your latin is not so great, it says “I scream, you scream, we all scream for ice cream.” Well, perhaps
it says which
, been a long time since latin class.

In terms of what went wrong. I overestimated the height needed so the text it a bit too raised of the base. It does not feel completely right in the hand, additional like braille and so coinage. Looking additional at real coinage they have a few edges(called reeds). Adding those cleaned up the sides really greatly. Here is the 2nd attempt:

This time I in addition
printed them out in stainless steel as well as the polished metals. Steel has a minimum height of 3mm. The additional detail is advantageous and so I expected and the pricing is pretty really greatr. It does yet feel a bit heavy for a coin. I in addition
did a test with White Strong & Flexible coins, but I can’t say I quite
liked them.

You can turn it into your own coins here: Coin Example

This script uses concepts we have mostly may already
covered, but there are a few additional additional details of the Image3D datasource to cover. The initially is the useGrayscale method. The default operation is to presume your image is black and white. Under the covers we system
this into a distance alter. We do this so which
lower resolution images looks advantageous. For greyscale imagery we can’t do the same operation, we only take your image and use it to define the height. Black represents the top
points and white the lowest. Think of this like your drawing with a black pin, your ink turn it intos 3D geometry, the darker it is the additional of it.

The 2nd concept is the image placement options. When we turn it into the geometry of an image it has a few modes. These are based off the setImageType and setImagePlace. The image type says whether we creating an embossed or engraved image. An embossed image has the darkest points going upwards whereas an engraving has the darkest points going downward into the object. The placement options say how the image is placed in the image box. Top placement puts the image in the upper area of the box, bottom does opposite. Both mode has the image in the top and bottom of the box. The next diagram gives a visual reference of the various modes:

Coins are fun way to begin
into the 3D printed metals. If you turn it into your own coins or improve my script post into the forums and show it off.
