![]() ![]() I imported the stand-in build area and all parts into an Inventor assembly initiated from the mm template. The z dimension is not important since this is only used to position the parts in the x-y plane. I sketched a rectangle constrained to the dimensions of the build area (64mm in the x direction and 40mm in the y direction) and extruded it by 0.5mm. ![]() I started by creating an Inventor part to represent Ember’s build area. ![]() The support geometry was added to each bolt model by creating a sketch referenced against the bolt geometry that was then extruded and patterned.Īfter preparing all the individual parts, I leveraged Inventor assemblies to layout the parts for printing. While it is possible to use MeshMixer to automatically generate supports for Ember, I manually created support geometry for the bolts in Inventor. I did not need any support geometry for the nuts since the “aspect ratio” of those parts led me to believe that the surface area of the part is sufficient to enable successful printing. Subsequently, I added support material to further anchor the bolts to the build head. When creating the part in Inventor, it is important to start with the mm template to ensure compatibility with Ember’s online slicer.Īs the z dimension of the part increases, additional torque is generated at the build head-part interface due to the separating action of the printer. Additionally I opted for fine threads when possible to further highlight the high-resolution capabilities of the machine.Īfter downloading the models in 3-D Soldworks format, each file was imported into inventor to create a corresponding Inventor part file. In an attempt to get an idea of the limits of the printer, I chose parts featuring the smallest thread size listed up to a ¼-20 fastener that has features that I expected Ember to resolve without issue.
