Saving and exporting files After your files are designed, your model needs to be tessellated, or converted into triangles, which are used by the printer to create layers. Tessellation occurs when you save or export your model file into specific file formats. The HP SmartStream 3D Build Manager accepts four different file formats: ● 3MF NOTE: 3MF is the preferred file format for HP SmartStream 3D Build Manager. ● VRML 2 (.wrl) ● OBJ ● STL When saving or exporting your file, note that a normal file size for a model is about 1-200 MB, but the size depends on the type of software that created it, the number of triangles, the number and level of details, and so on. HP does not recommend working with files of more than 4 GB-beyond that size, the extra resolution in the file may have no effect on the printed part. When exporting to STL, OBJ, or VRML 2 from a CAD package, you are often required to introduce some parameters such as angle tolerance and deviation chord height. These parameters define the resolution and file size of the part. The recommended parameters when exporting parts are an angle tolerance in the range 1-5 and a deviation chord height in the range 0.05-0.2. The angle tolerance should be reduced for parts with cylindrical or spherical shapes, and the chord height should be minimized for parts with fine details and small features. Below, you will find some recommended export parameters/settings for common 3D modeling programs.

Saving and exporting ﬁles

After your ﬁles are designed, your model needs to be tessellated, or converted into triangles, which are used by

the printer to create layers. Tessellation occurs when you save or export your model file into specific file formats.

The HP SmartStream 3D Build Manager accepts four diﬀerent ﬁle formats:

●

3MF

NOTE:

3MF is the preferred ﬁle format for HP SmartStream 3D Build Manager.

●

VRML 2 (.wrl)

●

OBJ

●

STL

When saving or exporting your ﬁle, note that a normal ﬁle size for a model is about 1–200 MB, but the size

depends on the type of software that created it, the number of triangles, the number and level of details, and so

on. HP does not recommend working with ﬁles of more than 4 GB—beyond that size, the extra resolution in the

ﬁle may have no eﬀect on the printed part.

When exporting to STL, OBJ, or VRML 2 from a CAD package, you are often required to introduce some

parameters such as angle tolerance and deviation chord height. These parameters deﬁne the resolution and

ﬁle size of the part. The recommended parameters when exporting parts are an angle tolerance in the range

1–5 and a deviation chord height in the range 0.05–0.2. The angle tolerance should be reduced for parts with

cylindrical or spherical shapes, and the chord height should be minimized for parts with ﬁne details and small

features.

Below, you will ﬁnd some recommended export parameters/settings for common 3D modeling programs.
