Design and printing guidelines

Introduction

3D printing oﬀers a much higher level of freedom in terms of design than any other traditional manufacturing

technology. Designers and engineers can beneﬁt from this, and use new geometries and concepts that were not

feasible before. However, in order to optimize the design to be printed with MJF, you should be aware of some

characteristics of the printing process and its capabilities, as this could help to get the best of the technology.

The design and printing guidelines oﬀer an overview of the steps to follow before sending a job to print, from ﬁle

preparation to the considerations that should be taken into account in the design of the parts and the orientation

of them in the build chamber to optimize the ﬁnal part quality and printing performance.

File preparation

File usage in the end-to-end workﬂow

In the end-to-end workflow of the printing process, the files pass through different software applications.

For example, the ﬁrst design may be done in a CAD program, while the job preparation will be handled in

HP SmartStream 3D Build Manager. If required, the printed part can be scanned in 3D and compared with the

original design.

Minimum speciﬁcation for parts

When designing parts in your 3D modeling software, HP recommends keeping this minimum speciﬁcation in

mind to avoid issues with parts and to achieve the best quality.
