This article will discuss the considerations for 3D printi......

Design Considerations: Common 3D Printing Problems to Watch Out For

JLC3DP summarizes the problems encountered in 3D printing from the perspective of materials, with the aim of reminding 3D printing users to avoid some design misunderstandings. 1. Resin material case analysis 1.1 Flat and thin shell models are designed with thin wall thickness, which will easily cause deformation, warping and missing. Suggestion: The overall wall thickness of the resin should be designed to be more than 1.5MM (the thicker the wall thickness, the smaller the deformation amplitude) 1.2 ......

How to Decimate the Size of an STL File for 3D Printing

Why is it necessary to reduce the size of an STL file? While large 3D files may not pose a theoretical problem, the practicality of sharing or uploading them may.
