DIY Dual Extrusion

Dual extrusion 3D printers are not as uncommon as they used to be, but there are still a lot of single-extruder machines. [Paul Lang] wanted to refit his printer to take two MK8 extruders, and he documented his experience with a blog post that has a few good tips if you want to try it yourself.

[Paul] used Fusion 360 to design a holder for the extruders that would fit his printer. Since he had accidentally ordered a spool of pink PLA, the whole assembly is shocking pink — not subtle at all. He shares a few design tips about …read more http://pje.fyi/Pg4Jn2

3D Printing Flexible Surfaces out of Non-Flexible Material

Here’s some interesting work shared by [Ben Kromhout] and [Lukas Lambrichts] on making flexible 3D prints, but not by using flexible filament. After seeing a project where a sheet of plywood was rendered pliable by cutting a pattern out of it – essentially turning the material into a giant kerf bend – they got interested in whether one could 3D print such a thing directly.

The original project used plywood and a laser cutter and went through many iterations before settling on a rectangular spiral pattern. The results were striking, but the details regarding why the chosen pattern was best …read more http://pje.fyi/PdDCw3

Using 3D Printing To Speed Up Conventional Manufacturing

3D printers, is there anything they can’t do? Of course, and to many across the world, they’re little more than glorified keychain factories. Despite this, there’s yet another great application for 3D printers – they can be used to add speed and flexibility to traditional manufacturing operations.

A key feature of many manufacturing processes is the use of fixtures and jigs to hold parts during machining and assembly operations. These must be developed before manufacturing begins and must be custom made to suit the given application. Many manufacturers outsource the development of such fixturing, even in large operations – even …read more http://pje.fyi/PVt2hn

The 3D Printer Packing Problem

Form Labs recently announced the launch of the Fuse 1, a desktop SLS printer that will print all your parts using nylon powder and a laser. This a fundamentally different method of 3D printing as compared to filament-based machines, and the best way to use a Fuse 1 is to fill the entire volume of the machine with 3D printed parts. [Michael Fogelman] decided to investigate the 3D packing problem, and managed to fill this printer with the maximum number of 3D printed tugboats. If you’re wondering, it’s 113, as compared with 82 tiny Benchies using naive bin packing.

The …read more http://pje.fyi/PR44VZ

Holman is Your Phone’s Best Friend

Let’s get something straight right up front: this isn’t much of an electronics project. But it is a very artistic 3D printing project that contains some electronics. [Sjowett] used an off-the-shelf class D amplifier with BlueTooth input to create a simple BlueTooth speaker with a subwoofer. As you can see from the pictures, woofer is exactly the term to use, too.

The clever mechanical design uses 3D printing and common metric PVC pipe. That’s a great technique and resulted in a very clean and professional-looking build. If you don’t have easy access to metric pipe, you could print the pipes, …read more http://pje.fyi/PNJwGg

PrusaControl: The Beginner’s Slicer

There are two main applications for managing 3D prints and G-Code generation. Cura is a fantastic application that is seeing a lot of development from the heavy hitters in the industry. Initially developed by Ultimaker,  Lulzbot has their own edition of Cura, It’s the default software packaged with thousands of different printers. Slic3r, as well, has seen a lot of development over the years and some interesting hacks. Do you want to print non-planar surfaces? Slic3r can do that. Slic3r and Cura are two sides of the CAM part of the 3D printing coin, although Cura is decidedly the prettier …read more http://pje.fyi/PLtG99
