Stratasys 3D Printing: Splitting Large Parts to Print in Multiple Pieces

Splitting Large Parts to Print in Multiple Pieces   Bigger might be better, but it might not be necessary. When searching for the right 3D Printer, you should always to try to find a machine that can fit no less than 75 % or 80% of your parts. But it doesn’t have to fit every single one. Don’t sacrifice quality, price, or capability for a large unnecessary build volume. Printing parts in two or more sections is much easier than you’d expect.   Here is a quick tutorial on how you can best split your large parts into printable sizes:     Using Stratasys software, Insight, you can split an

Stratasys 3D Printing: Reducing Time and Costs of Composite Tooling with FDM

Reducing Time and Costs of Composite Tooling with FDM     3D Printing your master tooling for a composite layup part can be a great way to reduce time to part and overall costs. Composite tools made with Stratasys’ FDM technology are just as effective and can create parts of the same quality as traditional methods. With traditional manufacturing methods, the time and cost to produce a tool drastically increases with its complexity. However, this is not the case with 3D printing. This introduction to composite tooling with Stratasys FDM will help you decide if FDM is the right process for your needs.   Using FDM for this application is

Stratasys 3D Printing: Different 3D Printing Technologies

While Stratasys has always been the pioneer of 3D printing, it’s important to know that there are many different types of technologies and materials surrounding 3D printing, also known as “additive manufacturing”.   Stratasys 3D printers use one of two technologies. The ever popular “Fused Deposition Modeling”, FDM, and the “Polyjet” technology.   FDM FDM is the main 3D printing technology that everyone knows about and has seen. Real engineering grade thermoplastics are made into a filament, round up in a spool, and then fed from the spool to a heat extrusion tip and laid down layer by layer. Like a hot glue gun affixed to a CNC milling machine,

Stratasys 3D Printing: Self-Supporting Angles with FDM

Self-Supporting Angles with FDM   Looking to save some time when printing with FDM?   Generally, in 3D printing processes when there is some of overhanging feature, support will be required to be underneath. The time it takes to switch between support material and model material can add up to a lot by the time the build is finished. However, when using the FDM process, there is a degree of self-supporting angles that can be utilized to greatly reduce printing time and material use. These advantages can be used with all FDM machines; from the UprintSE to Fortus 900mc.   The general rule for the minimum self-supporting angle is around

How to Insert a Pause in a Build in Catalyst

In Catalyst, you can tell the machine to pause at a specified layer during a build. Once the build pauses the door will unlock. You can use this technique to insert parts into the build in places that would otherwise be inaccessible. Regardless of the part inserted, it must sit flush with the last layer that was put down. You can also utilize a pause in the build to do a material change. Once paused, unload the model material and load a new material cartridge just as you normally would. This allows you to have multi-color parts. Use this technique to give emphasis to a particular part of a model
