A subtle artefact of stacking leaves in an array is the issue of pseudo-shortening. Being on the continuing quest to make the perfect iris design, it’s certainly a factor to consider when creating an iris diaphragm. So what do I mean when I use the term pseudo-shortening? Let’s start, like all great iris designs, by […]
Designing an iris to be easily manufactured is obviously advantageous. One particular challenge is making the leaves with pins on opposite sides, and is a common limitation associated with 3D printing on a FDM printer (also known as FFF). This is because parts generally benefit from being printed flat (see my previous article). With these […]
Projection welding is a form of spot-welding, whereby a protrusion of material from one metal part is melted into another, forming a solid bond. This is a particularly useful technique when you have mismatched material thicknesses – such as a solid pin being welded onto very thin leaf material. To make this work for us, […]
This is a guide on how we currently cut the slot for the irises handle in our steampunk goggles. If you’ve bought the Steampunk iris from our store, you may find it useful to follow, or modify, these instructions to cut the slot in your own goggles. For those of you that have a 3D printer, we’ve included a template for you to download and 3D print to help aid the process.
It’s rare to encounter a problem with an iris, but if there’s going to be a failure anywhere, it’s usually a pin breaking or jamming. The latter causing the leaf to scrunch up, taking a neighbour or two with it.
All products have an expected lifespan, and irises are no different. So how many aperture cycles could an iris endure during it’s entire life? This is an answer I’m curious to find out…
Here’s a short video demonstrating 5 steps to making Steampunk goggles mechanical iris diaphragm. Once you’ve 3D printed the parts it’s relatively straight forward to put together.
3D printers are incredible pieces of tech. With the lowering the costs of FDM (Fused Deposition Modelling) printers in recent years, it has enabled desktop fabrication to reach the masses – both in the small business environment, and in the home. Sometimes, however, printing a seemingly simple object can also prove to be equally impossible. Including a way to 3d print leaves for an iris diaphragm…
No matter who you are, no matter where you’ve been, there’s always some (good) distractions from the usual work. This time around it was creating a small toy, to go in loot bags for a PJ Masks themed party… Because sometimes even the smallest client is the most important!
