QuickCast patterns were the first direct pattern (patterns created via a 3D printing process) and are by far the most popular direct pattern technology in North America. With Quickcast patterns, castings can be created without the time-consuming process of creating tooling to produce wax patterns, allowing the design to be evaluated in days instead of months. The cost of QuickCast patterns is typically a small fraction of what tooling costs and they are available in less than a week, so fully machined impellers are available within three weeks. The resin-based patterns from Quickcast are hollow with a unique internal honeycomb structure that allows the pattern to collapse internally as it expands with temperature. It also minimizes the material in the pattern, resulting in an almost ash-less burn that enables a cast to be created quickly and without a lot of additional steps. Tech Cast and 3D Systems worked together on a study to quantify the advantages of their process. A double suction impeller about 15 inches in diameter (pictured right) was chosen for the study. Castings were created both with molded wax patterns and with SLA QuickCast patterns supplied by 3D Systems.Ĭosts and timing were recorded at each step of the casting process so that an accurate comparison could be made. The customer can go through at least two iterations in the time it would take to get the first casting from the conventional process.Īssume that when the first casting is tested, the performance is not acceptable. The manufacturer will make an engineering change to improve the performance and request a second impeller to test. If these are challenges you are encountering, would be curious to have an exploratory discussion.The foundry will then create the casting model of the modified design. We have been talking through flexible and scalable models that allow for support, but don't require the long term commitment of an FTE or outsourced agency model.

Ensuring that if a customer launches a new product, site, etc what is the immediate return the end customer will see and revenue it will create.Ģ.) Seeing a lot of customers that may not have the ability to bring in full time resources due to budget/headcount restraint, but the amount of design work on the roadmap hasn't changed. #networkġ.) Extra time and validation on the user research and workshop front. I'd love to hear from others in the UX space if this is happening within your organization. There are a few themes and trends that continue to arise that I felt may resonate with my network here. I have been meeting with a lot of UX Design teams and leaders lately to understand how some of the challenges the economy is presenting are impacting their groups.

Review announcements and speaker bios in advance. You don’t want to read them for the first time in front of the audience a session chair who stumbles through announcements doesn’t come across as professional. Ask speakers how to pronounce their name before introducing, if necessary. Don’t take liberties or make jokes about the bio you might know the person well, but the audience does not. Vibrant Q&A is a good thing. Combative Q&A is not. It should be quashed quickly and respectfully. Ditto for commercialism. Ditto for long-form, rambling, grandstanding questions (it’s called “Q&A”, not “comment time”). Respect for industry veterans and VIPs is healthy even so, this does not give them special permission to command the floor during Q&A. Be ready and willing to shut people down if needed. It is best to press for timely submissions of presentations. Even so, your presenters might come to you with a late revision. This should not be a crisis.ĩ. You have a rough idea how many people are attending. Even so, you should plan for late arrivals/registrations. Nobody likes the disturbance of furniture being set up after the speakers have begun.
Microphones and projectors should work without drama. Screens should be large enough and numerous enough for the entire audience to see them without laboring. Below is the rest of the list of the Top Ten Things you should do as a session chair. The first five things are in a separate post.
