Hi there.
I have a question about 3D-printing, and I will be grateful to answer my questions.
I have designed a re-entrant auxetic structure in SolidWorks and exported it as an STL file, and printed via FDM 3D-printing. The material is PLA and I used Cura to generate g code. All the thicknesses in the SolidWorks are 0.8mm, but the thicknesses in the printed structure are different. According to the attached picture, the thickness of top strut, bottom strut and all inclined struts is about 0.8mm, but the thickness of all horizontal struts is surprisingly near 1mm. What is the problem?
Dear Amirhosein Naghizadeh
Horizontal supports may be thicker due to layer height and layer buildup since they are printed in a different orientation during printing. You can check the "Line Width" setting in Cura and optimize it to suit your nozzle diameter or try changing the printing orientation or set different printing parameters of horizontal and inclined supports.
Kind Regards.
Dear Amirhosein Naghizadeh,
Horizontal structs thickness increased due to moving the nozzle in straight direction try to optimize the overlap percentage in CURA software and material flow rate while printing to optimize the thickness of the horizontal struct. Also, check the layer width to control the the thickness of struct.
