きれいなはずの螺旋 3D 印刷のモデルたとえば球をグラフィクスで表示してもモアレ縞が生じる．これは，フィラメントがつくる線とピクセルがつくる線との干渉でできたものだ． Moire fringes occur even when a model of helical 3D printing that should be beautiful, for example, a sphere is displayed in graphics. This is the result of interference between the lines created by the filament and the lines created by the pixel. A helical 3D printing API in Python is available at bit.ly/3o3I8VL .

A delta-type 3D printer is printing a shade (bulb cover) of a chandelier lamp by helical 3D printing method. This type of patterns is explained by a short paper bit.ly/2WQv2y1

A method of pattern generation by the helical 3D printing, which is called “modulation”, is demonstrated by a video. The velocity of the print head is changing. A simple sine wave pattern is generated. For the helical 3D printing, look at www.kanadas.com/papers-e/3d_printing/. A helical 3D printing API in Python is available at bit.ly/3o3I8VL .

A method of pattern generation by the helical 3D printing, which is called “vibrato”, is demonstrated by a video. The print head is moving up and down. A simple sine wave pattern is generated. For the helical 3D printing, look at www.kanadas.com/papers-e/3d_printing/. A helical 3D printing API in Python is available at bit.ly/3o3I8VL .

A method of pattern generation by the helical 3D printing, which is called “deformation”, is demonstrated by a video. The print head is moving left and right. A simple sine wave pattern is generated. For the helical 3D printing, look at www.kanadas.com/papers-e/3d_printing/. A helical 3D printing API in Python is available at bit.ly/3o3I8VL .

This cat toy contains no batteries but it generates electricity by moving it. Its motion is more interesting than its flushing light.

This pot was generated by helical 3D printing method. Three waves were combined to generate this very fine moaré pattern. Two "vibrato" waves were generated by shaking print head vertically and one "deformation" wave was generated by shaking it horizontally. This pot reflect and refract light in a complex manner. This printing method is explained more in my blogs (bit.ly/2GOimBH, bit.ly/2EhHonl).

Two 3D-printed disks with spiral filaments were used. One of them is a precise spiral and the other is a waved spiral (with Fibonacci waves). You can see Fibonacci patterns and other moiré patterns in this video.
