The Creality Ender 3 has an issue with filament chafe. With the filament lead coming down from above the machine there is a sharp corner at the extruder that chafes away at the filament. Designed to slide over the existing Z screw nut, the gentle curve of this large radius bearing is one solution to… Continue reading Ender3 filament guide bearing

Salve Flask – Stand and funnel
The stand is modeled to fit a previously existing Flask by a Swedish brand called Low Key Goods. This flask does not have a base, therefore cannot stand on its own. Flask body is modeled using the Form workspace in Fusion 360. The stand is in two pieces which allows for 3D printing without support.… Continue reading Salve Flask – Stand and funnel

CAD model drawn from original drawing in the Sjöhistoriska museets arkiv. (Swedish naval history museum archives).
Fixture
For the parts to easily fit one another, maintain alignment to allow assembly, and be easily removable from the form after assembly, a clearance of 0.6 mm is designed into the fixture. FDM printers have some limitation to their accuracy. This limitation is typically accounted for by designing in some offset or clearance tothe parts. If the… Continue reading Fixture

Topology optimization and FEA
Topology optimization takes a series of steps from original shape to optimized result. Either in Altair inspire or Autodesk Fusion 360, the programs have a very straightforward workflow already laid out as a linear progression … We want to minimize mass while maintaining stiffness. In this case we must take into consideration all features that must… Continue reading Topology optimization and FEA
Loket 6
Designed to be 3D printed in place and without any support, this locomotive pulls all the stops when it comes to DfAM (Design for Additive Manufacture). Wheels unclip and shear open, the cabin is removable and the smoke prints with a second color.
Design assignment from 3d-printingspecialist. Based on traditional Swedish LOKET machinist practice.
Injection mold inserts
New materials for AM, like Ceramic resin printing, gives the opportunity for faster and cheaper printing. New or yet developed AM methods or post processing techniques could produce finer surface details eliminating the need for traditional manufacturing for complex injection molding tooling. Some polymer AM, like continuous resin printing, and metal AM, like single pass… Continue reading Injection mold inserts
