Greatly Improve Portable Air Conditioner Efficiency

Wed, 23 Jun 2021 11:30:38 +0000

Ducted, portable air conditioners suffer from terrible efficiency inherent to their design. Here is how they work and how to improve portable air conditioner efficiency.

Portable (Air-to-Air, Monobloc or Ducted) Units

If you, like many others, find yourself unable to install a split or central air conditioning system due to rental agreements or insulated windows, your options for cooling are limited. Portable air-to-air units, despite their convenience, come with a significant design flaw that compromises their effectiveness. In this article, we delve into the drawbacks of these units and shed light on the inherent problem that plagues 99% of the available commercial models.

Simple 3D printed Kärcher SC3 Power Cable Holder

Thu, 28 Jan 2021 23:09:49 +0000

I’ve nearly completed the first semester of my two-semester CAD course at my university, and now for the first time have started to feel comfortable enough to use these newly acquired skills to design things that have a real-life application. That is how a 3D printed Kärcher SC3 Power Cable Holder became my very first functional CAD and print.

The Problem
#

My parents own a Kärcher SC3 EasyFix steam cleaner, and one of her most common complaints was the inability to store the power cable of it satisfyingly. The cable would dangle around when carrying the device and be an overall nuisance. I mulled the problem over in my head somewhat, starting as to where one could even securely attach an accessory to an object that consists of smooth, curved plastic surfaces.

A sleek Prusa i3 MK3S Raspberry Pi 4 Upgrade

Running a Prusa i3 MK3S with Octoprint definitely improves the overall printing experience. You can quickly upload print jobs from the slicer and check on the printing process remotely. Prusa even has a guide on how to install a Raspberry Pi Zero W directly onto the EINSY board. However, the little board struggles to run Octoprint and in some cases it can even cause layer shifts that ruin a print entirely! Doing a Prusa i3 MK3S Raspberry Pi 4 Upgrade is a little more effort, but absolutely worth it.

3D Printing Safety

What are the health risks of 3D printing?
#

Appropriately dealing with health hazards is (hopefully) nothing new in our workshops and maker spaces, and just with any other tool it is important to analyse and mitigate the health risks, to ensure 3D printing safety. This article concerns common safety hazards of fused filament fabrication printers.

Mechanical Hazards
#

All parts of the 3D printer that move pose the threat of injury. Examples include: flywheels, pulleys, belts, couplings, chains, cranks, gears, etc. The feed mechanisms and auxiliary parts of the 3D printer should also be considered.

3D Printer Emissions of common filament types compared

3D printers can create harmful fumes
#

FFF 3D printers are a major source of VOCs and ultrafine particles, both of which can be harmful to your health. While this can vary drastically on the filament type, it is still advised to reduce your exposure to 3D printer fumes. There’s a continued research effort in comparing 3D printing filament emissions with each other.

The number of studies regarding 3D printer emissions is still relatively small, and has until very recently only considered basic filament types such as PLA and ABS1. PLA is fairly benign, as it mostly consists of mostly harmless components. Acrylonitrile butadiene styrene (ABS), as the name suggests, emits large amounts of styrene when heated. Hardly any studies have compared these filament types with the more modern alternatives on the market. I was especially interested in the performance of PETG, and I’ve found this study that has a closer look.

3D printer resin made in the EU compared

The market for 3D printer resin is, perhaps unsurprisingly, far smaller than the one for 3D printer filament. However, there are still several manufacturers that offer 3D printer resin made in the EU.

With Anycubic’s release of their new series of Photon Mono resin printers, I started looking for 3D printer resin to buy in preparation. For similar reasons as I had stated in my 3D printer filament article, I wanted to buy resin that was made within the EU. And again, despite being made in the EU and under EU law, there are a bunch of resins available that aren’t too expensive either.

Ideal server rack 3D Printer Enclosure

The Enclosure
#

A 3D printer enclosure perfect for a Prusa i3 MK3S, made of powder coated sheet-metal and has a safety glass door.

Even before I received my 3D printer, I was looking for an appropriate enclosure. I did that for two reasons: One being that filaments apart from PLA tend to warp outside the stable temperature environment an enclosure provides, and two being that I wanted to reduce the toxic emissions and noise of the printer.

3D Printer Filament Made in the EU

Sourcing “ethical” 3D printer filament
#

*There’s an abundance of 3D printer filament manufacturers on the market. While there is a plethora of reviews and tests regarding their quality and price, far too often the circumstances under which they are made is disregarded. I was looking for filament made in countries that have acceptable human right standards and labour laws. That’s why here’s a list of 3D Printer Filament Made in the EU.*

While globalization certainly has its upsides, I’ve come to try to source things I purchase from Germany (or any other country within the EU) whenever I can. This is also the case for 3D printer filament. Naturally, I looked around.
