Quick post to show you some photos from my visit to Portland this week. As the title implies, Portland is a haven for makers, urban manufacturers, craftspeople, artisans, and it is an amazing place to hangout. My first stop was in North Portland to the home of TiCycles — handmade bicycle makers.
They are experimenting and exploring #3DPrinting parts for their titanium cycles. I heard about them while on the 3DRV trip and had been itching to visit for quite some time. They had the big NAHBS (North American Handmade Bicycle Show) to prepare for, so I was incredibly grateful for some time with Dave and his team. Another visit is in the works, but for now, check out these few photos and explanations.
On the path to testing various 3D printed ideas, they received two tube-like sleeves that fit inside one another. They welded them together (take a close look at the bead below, clean) and decided to apply some pressure. EIGHT TONS of pressure. That’s how much it took to bust it. So if someone tells you that 3D printed metals don’t have the same structural integrity as a milled part, that is not always true.
You can see a bit more of the crack, breakage, after all that pressure. 16,000 pounds worth.
And just another view here:
Finally, a wicked weld bead.
Take a visit to the TiCycles site.
I drove to Portland to hang out with a few people to talk about the HP Sprout #GoMakeThings project, to hear the latest from area makers, inventors, business owners, and, a very pleasant surprise, to sit down with Gregg Meyer, the Interim Dean of Math and Industrial Technology at Portland Community College.
Sit down is not accurate — we ran around multiple buildings and areas so that he could show me the amazing maker space that the college is creating. I am impressed and am working on a longer post on his efforts; post due out in early March.
