Pre-Printing Tips for Rigid Opaque and Transparent PolyJet Materials

Alexa Nahum
in 3D Printing
13 13 Beginner
This tutorial gives you tips for how to use various rigid materials on Stratasys PolyJet printers. This includes the entire Vero family, as well as the VeroVivids, VeroFlex, VeroClear, and FullCure720 (also known as RGD720). You can truly optimize final results for these materials if you know how to best utilize GrabCAD Print settings for part orientation, printing mode, surface finish, grid style, material selection, tray preparation, and other factors. Below, we will show you how. The information in this tutorial is applicable to GrabCAD Print version 1.32 and above. Older versions may differ slightly.

Designing a Hirth Spline

Tjerk de Graaff
in Theory
24 8 Beginner
Solidworks + Excel instruction on how to design a Hirth Spline. Background on Hirth Splines: https://en.wikipedia.org/wiki/Hirth_joint The basic idea of a Hirth spline / Hirth Joint is that the whole geometry is defined from a combination of a single reference point and a grinding/cutting geometry. Two Hirth splines with the same basic tooth geometry will match to form a secure joint that can transfer torque and allows for accurate alignment of parts. Hirth splines and joints are often used in turbomachinery to accurately align various shaft parts and transfer torque.

How to Print Remotely on the Stratasys F123 Series Using Wait For Part Mode

Stratasys
in 3D Printing
10 7 Beginner
The new Stratasys® F123™ Series can print industrial-grade, reliable concept models, functional prototypes, jigs, and fixtures. In applications such as these, printer operators will often want to print parts quickly, remotely, and on-demand. That is why this series has a Wait for Part Mode, letting you send files straight to the printer to start building immediately, without needing to select the job manually from the Queue. This tutorial will explain how to use this mode.

Axle Load in a Railway.

Carlos Soler
in Theory
3 5 Beginner
General considerations about axle load in a railway and its importance in the design. Axle load is the weight on the two wheels joined by an axle. (static vertical load per axle); It is, basically, the total weight bearing on the track. If you have two wheels attached to an axle, with an AXLE LOAD P =225 kN, you have a load in each wheel of Q = P/2
