Overhang Analysis Function

 

    In 3D printing, it’s very favorable if object is perpendicular to bed surface, more horizontal the shape is, 

 

    the more disadvantageous it is. When the angle in horizontal direction is small, supports are needed. 

 

    The Overhang analysis function calculates the geometry’s inverse draft and notifies the user of possible   

 

    problems that might occur during an actual printing.

 

 

Function to Calculate Optimal Printing Direction 

 

3DWOX has a feature which caculates and recommends the user the most optimal direction for printing. 

 

On the basis of pre set standards,this feature caculates 6 different printing directions having the Bed as the    

 

base and shows the optimal direction to the user. There are 3 types of evaluation criteria and explanation for each  

 

type is as follows.

 

Estimated Printing Error Surface

 

  Using thickness analysis of the 3D model, the function calculates the area of the part thinner than the 

 

  current nozzle diameter. For areas which are thinner than the nozzle diameter, there is an extensive chance  

 

  that the model may not accumulate as expected. So the program pre-calculates these to find printing errors.

 

Overhang Surface

 

  Through Overhang analysis, the program takes into consideration of errors that might occur during printing. 

 

  Smaller the Overhang surface is, better the quality is. Thus, considering the calculated area value in the 

 

  opposite way, the optimal printing direction is determined.

 

Amount of Support

 

  Where there is an Overhang, support is needed for a normal accumulation. However, more supports 

 

  there are, lower the quality and longer the printing duration becomes. 

 

  Taking the factors into consideration the program pre-calculates the optimal printing direction.
