The BQ Hephestos2 (3D printer), nine months later

After nine months I can say that I’m satisfied with the BQ Hephestos 2 printer. It’s easy to print with and easy to maintain. It doesn’t come with a heated printbed which I consider a shortcoming but for PLA and Filaflex the printer works fine.

Introduction

It’s been nine months since I received and assembled my BQ Hephestos 2 printer and I think it’s time to share some of the experiences that I had with it. For those who don’t know the Hephesthos 2 it’s a 3D-printer that is based on the Prusa i3 design with a thick steel frame and almost all metal parts. It’s not cheap but it’s a well designed, high quality 3D-printer with a large printbed. It does have it’s shortcomings but more of that later.

Using Filaflex to improve my cooler

Filaflex is excellent material to improve the audio cooler that I made earlier. The material is very flexible and surprisingly strong making it perfect for sealing purposes

Introduction

A week ago I finished my audio cooler. Although I was happy with the result improvements could be made (as is always the case). Most important I didn’t particularly like the console on the side of the coolers lid. This was a 3d printed part of PLA that I glued to cooler with a superglue. This was far from ideal because of the space left between the printed console and the cooler . Another improvement could be made by the way that the speaker was fitted to the lid of the cooler. The speaker was directly attached to cooler with four screws again leaving some space between the two. I already had some FilaFlex filament but hadn’t used it yet. Because of the elastic and flexible properties of Filaflex I figured that I could both fix the issues with the console and the speaker.

Left the cooler with improved speaker and console and right "old cooler" with printed part of PLA filament.

Audio system for cooler almost finished

A made a 3d printed enclosure for the audio components that fits in the coolers lid together with a simple console to operate the audio

Introduction

A couple of weeks ago I started to make a tiny audio system for our cooler. In my previous blogpost I described all the audio components that I chose for this project. I wanted the components to be small since I didn’t want to waste too much space in the cooler. With the audio components in hand I could design other parts for the audio system. I needed an enclosure for most of the audio components and a simple console to operate the audio. The parts were 3d printed with my Hephestos 2.

Assembling a Hephestos 2 printer

Is this 3d printer a good choice for a beginner?

Introduction

While making my projects like the Darth Vader chest box 2.0 I use the local fablab a lot, especially the laser cutter and the 3D printer. It was a bit boring to wait for the 3D print to finish (laser cutting is typically much faster) with not much else to do at the fablab. I therefore decided to buy my own 3D printer. I choose for the BQ Hephestos 2, a sturdy Prusa i3 all metal printer that comes in a kit. Continue reading “Assembling a Hephestos 2 printer”
