Straight Talk On 3D Printing Footwear At Home

Printed footwear is an intriguing idea, but as far as projects go it is somewhat more complex than it first appears. This guide to 3D printing your own clogs not only provides a solid process, but also acts as a list of the challenges and pitfalls involved. After all, a piece of footwear is actually a fairly large object. Failed prints can be costly and time-consuming, so a guide like this is a valuable resource.

First of all, a 3D printer that can handle multi-material printing is called for. The footwear itself will be printed in TPU 90A as a sweet spot for hardness, but the print will require supports and those supports will need to peel away cleanly. The solution is a shoe printed in TPU with a rigid support structure of PLA. Using two different materials in the same print with anything remotely resembling efficiency calls for either a dual-nozzle print head, or a multi-toolhead printer.

3D printing one’s own clogs can be rewarding, if not necessarily cost-effective.

Here we want to take a moment and say that while the guide itself suggests PETG is also a suitable support structure, we suspect this might only be true for the exact filament formulations used in the guide. The safer approach is to use PLA. Why? As we’ve seen in other tests, PETG has been observed to stick extremely well to flex filaments in general, whereas PLA doesn’t really want to stick to anything other than PLA. The exact formulations of TPU and PETG used in the guide might be compatible with one another, but in general we recommend sticking to PLA as a rigid support for flexible filament.

Assuming a capable printer and suitable materials are nailed down, one also needs to worry about keeping the TPU dry. It is very sensitive to moisture, which directly affects print quality. You’ll also need to dial in the settings — a gyroid-patterned infill of 15% provides the right amount of “squish”, which is most effectively fine-tuned by changing the infill pattern rather than the density.

Is it worth the time and effort and filament cost to print one’s own pair of slip-ons versus simply buying a pair of Crocs®? Maybe not, but it can still be rewarding and this guide will help minimize any failed prints in the process. And if you do get a nice print but the TPU is sticking a little too well to the build plate, reach for the isopropyl alcohol.

Only 90s Kids Want Heelys Made From Pallet Wood

The kids are simply cooler than you. While you’re walking around using your feet like an animal, kids have shoes with wheels in their heels. These are called Heelys, and here’s how you make wooden clogs, with wheels in the heels, out of pallet wood. If you have to ask why, you’ll never know.

This build started off with a fairly large maple log, which would be the traditional way to build clogs. After taking this log to the bandsaw and looking inside, [Jackman] found a bit of spalting, or arguably aesthetically pleasing fungal growth. Whether the spalting would look good or not is a matter for debate, but either way [Jackman] decided to change plans and moved over to creating pallet wood clogs. A word of warning about pallet wood: you shouldn’t make anything out of wood from discarded pallets unless you know what you’re doing, and even if you do know what you’re doing there will be someone in the comments telling you that you shouldn’t use wood from discarded pallets. You can check out the comments to this article to verify this fact.

The construction of the clogs started with a few pieces of one inch stock glued up into a gigantic block, then several pieces of half inch stock resawn into quarter inch stock and laminated onto the sole of the clog. This was then shaped using a variety of tools from Arbortech; of note, we have the Turbo Plane, a wood shaping tool for a grinder that sounds more dangerous than it is, the Turbo Shaft, a plunge router or mortiser-sort-of-thing for a grinder that’s much cooler than it sounds, and the Power Chisel, something we can’t even believe exists and hold on here’s all our money.

These tools couldn’t get all the way into the toe of the clog, which meant [Jackman] had to saw down the middle and hollow everything out that way, but this did give him a nice flat surface on the inside to install the Heely wheels. This turns the clogs into something nine-year-olds simultaneously desire and don’t appreciate, because they’re kids.
