3D Printable DIY Moka Pot Made with Formfutura Volcano PLA

Stefan from CNCKitchen in Germany designed and successfully made a fully functional 3d printed coffee Moka pot. Due to high temperature needed to reach the internal water pressure he used Formfutura Volcano PLA. Do keep in mind that this is a demonstration and not everyday usage object. The pressure build-up in a closed plastic vessel can be dangerous.

Well, they look cool, but are they comfortable? I doubt it. I'm actually pretty certain that they are almost unusable. I like my cheap Chinese faux-leather lazy-boy copy, chewed out by my dogs, where I can chillax with beer and chips in front of the TV.

Hack a Coffee Maker into a Delta 3D printer

Tropical Labs team made a coffee maker into a Delta 3d printer. Interesting hack. Tropical Labs engineers have been developing a flexible design for ultra-affordable 3D printers and this a part of their efforts.

Video of the Delta printing:




Printer features:

• Coffee maker, Tropical Labs used an old Norelco 12 model they found at a thrift shop, but any coffee maker with a hot plate could potentially work 
• Arduino Mega 2560
• RAMPS 1.4
• A4988 Stepper Motor Driver Carrier
• Nema 17 stepper motors
• Home switches, optical or otherwise
• 3D printer hot end/extruder – again, any kind will do; Tropical Labs snagged theirs on eBay
• 12V power supply
• Solid state relay (Fotek SSR-40 or similar)
• Ball joints
• 4-40 threaded rod

Bake your PLA 3D prints in an oven for a higher strength

Thomas made an interesting experiment where he baked in an standard household oven some PLA (and other filament) objects. It looks like you can improve the strength significantly with this simple method.

See the entire process and measurements in his video:




With change in strength, there is naturally some shrinkage and expansion in different axis.

Let us know in the comments if you have simillar experiences with heat treated PLA or simillar materials!

Switcher DIY Power Modules For Smart Home Projects

Hristo Borisov developed and published a set of 3D printable socket and switch modules that are controlled by ESP8266.
ESP8266 is very interesting piece of electronics since it is very small, affordable (some 4 USD) and powerful since it has WiFi and can be used as Arduino.
With this project you can control your electric devices via WiFi remotely and setup a simple DIY smart home project for a fraction of a price of commercial proprietary solutions.

Sockets are fully 3D printable and are of standard European "Schuko" type, designed in Autodesk Fusion 360. Design is modular so you could probably easily change it to any other socket standard.

There is even an iOS app for remote control of modules. Project is also open source so they get extra pints in my book.

Project homepage with all the code and instructions:

GitHub repository with all the code and STLs:

https://github.com/hborisov/switcher_box

Stay safe when working with home electric power systems :-)

Update:

looks like there is a simillar commercial system that is also very affordable, but it is not open sourced:

https://www.itead.cc/sonoff-wifi-wireless-switch.html

It may be possible to flash it with custom firmware but it doesn't have a socket but the wires should be connected to it.

3D Printed and Laser Cut Open Source DIY Air Purifier

Ian van Mourik, a product designer from the Netherlands developed and open sourced an air purifier anyone can make. It is autonomous since it is controlled with Arduino and uses simple fans to move air trough particle filters and activated carbon.
It costs around 70 Euro. It has some laser cut parts from plywood but you could cut them manually or use different structural support since they are mostly decorative.
Looks like a great solution to improve your home air quality by removing dust and destroy mold particles or pollen (which I'm allergic to). Just keep in mind to change the filters or upgrade them with HEPA. Carbon filters get used up relatively fast.

Here is the video presentation:

Jonathan Odom's 3D Printable Wireless Lantern Based on Qi Inductive Power Technology

Jonathan Odom developed and shared his great looking DIY 3d printable LED lamp. This battery powered wireless charging lantern will glow for 1.5 hours on a single charge. It works with a few cheap electronic parts and a USB charger. The USB cable plugs into the base, and the lamp sits on the base and charges through induction via Qi Universal transmitter and receiver.
The lamp housing, charging base, and lens are all 3D printed on a almost any standard FDM printer since the lamp is a 5" X 5" (127mm X 127mm) cube.

Simple DIY Air Heat Exchanger You Can Make With Your 3D Printer

Air heat exchanger is a useful ventilation system part that will enable you to save energy while maintaining a good air flow in your enclosed space. It uses the outgoing air form the heated space to warm the cold air that is going from outside. Heat is thereby recovered and energy consumption for heating decreased.
They are mostly used in passive or low-energy houses or buildings, but they can be used in most insulated spaces. There are also applications where you can cool the air coming in.
The entire system is also called Heat Recovery Ventilation (HRV). You maintain air flow which improves indoor air quality, reduces bacteria and mold buildup, stabilizes the moisture but you don't need to open the windows and still keep some 70-80% of heat that would normally be wasted.

Yvo de Haas developed a small DIY 3d printable version that he implemented in his house with excellent results. The heat exchanger itself is printed in PLA while tubing is standard PVC with standard 60mm fans to drive the air. The electric fans can be noisy but they can be easily replaced with quieter ones.

He developed two versions of this DIY HRV: one that is partialy 3d printed and one that is fully 3d printed.

Here is what Yvo writes about the fully 3d printed unit tech specs:

The completely 3D printed version is, as the name suggests, completely 3D printed. To make it I modified my Ultimaker with an E3D V6 with 0.25mm nozzle.

The walls of the exchanger are 0.3mm thick. The outside dimensions of the exchanger are 15x8x7cm but it has an internal surface area of around 1000cm² (1/10th of a square meter or about a square foot). It is printed in PLA and takes around 10 hours to print at 0.16mm layer thickness.

With special adapters it can fit 60mm fans and all the other adapters I have designed special adapters were printed to connect the 60mm fans to the 3D printed exchanger.

Fully 3d printed heat exchanger element. Here is where the magic happens. 

Heat exchanger installed on the window with fan ventilators attached. 

Yvo measured and logged the temperature data:

The 4 temperatures (unit does not matter):

• Hot in (the warmer air that enters the hot side of the exchanger)
• Hot out (the warmer air that exits the cool side of the exchanger)
• Cool in (the cooler air that enters the cool side of the exchanger)
• Cool out (the cooler air that exits the hot side of the exchanger)

Does it work?

The answer, YES. After running for over 8 hours while I was at work, the air was a lot fresher. Usually when I come home there is a certain staleness to the air, but now I came home to nothing. Just nice air. I had the logger running for the entire time. The test started around 8 o'clock, every number on the X is 6 seconds. There are 3 zones of interest.

0-3000: Here the air outside is slowly heating up. Temperatures around this point are: HI: 17°C, HO: 10°C, CI: 6°C, CO: 14.5°C, giving 63.6% for the hot flow and 77.3% for the cool flow, averaging 70.5%.

3000-4000: Here the sun hits the window and there is a spike in temperature. No useful data can be gathered from this time.

4000-6000: The air outside is slowly cooling. Temperatures around this point are: HI: 17°C, HO: 12°C, CI: 8°C, CO: 15°C, giving 55.6% for the hot flow and 77.8% for the cool flow, averaging 66.7%.

Repairing fridge light switch with 3d printing

Nicholas Durdan, well known for using his 3d printer to repair broken parts on his Ford Focus made a DIY 3d printed replacement for a broken fridge light switch.

It is a perfect example of how home digital fabrication is changing the nature of replacement part economics.

Identify the broken part...

Pyra smart 3d printed oven or advanced heat chamber

Pyra is 3d printed smart oven. It can cook food but it can be used for any process that needs heat chamber. And yes, it is smart, Internet-of-Things device.It is open sourced also! Kudos!

Key features hardware:

• Built on Fortus 900MC 3D Printer
• Printed in ULTEM 1010
• FDA-Approved up to 375˚ F
• Raspberry Pi + Arduino
• WiFi Compatibility
• 12-Bit Digital Temperature Sensor

IoT capability:

• Thermal Chamber Software
• Smartphone Compatibility
• HTML5 Web App
• Cloud-Enabled
• Built on Meteor
• (Framework for Real-Time)

Other features:

• Designed for Additive
• Self-Supporting Structure
• (No Support Material)
• 80-hour Build Time
• 3D Printed Heat Exchangers
• Open Source

How it works:

A 3D printed fan in the base circulates air over heating elements and throughout specialized convective heating systems. The design eschews all the conventional wisdom of traditional manufacturing and embraces the capabilities of 3D printing.

This is evident through the design, from the profile of the complex heating channels to the shape of the smallest part in the heat exchangers 3D printed into the chamber walls. Even the overall shape of the Pyra was dictated by the constraints of FDM—sloping sides of 45 degrees are self-supporting and removing support material from the inside of the labyrinthine ductwork of the Pyra’s interior would be impossible.

Clean your house with 3d printed vacuum cleaner robot, 3d printed broom and antimicrobial kitchen scrubber

I hate house cleaning. I really do. It was a source of many arguments with my girlfriend in the past, but I think she got used to it now.
If you hate it also (or even if you like it), here are some DIY projects that can hel keep your house clean with a help of 3d printer.

We thought about buying roomba vaccum robot but it is just too expensive here in Croatia. There are several homemade Roomba clone projects but Jake Lee made a 3d printable DIY vacuum cleaner robot named Panda.

Here is a video of Panda in action:





If you want to make your Panda, here is a full build guide:

His friend used a cooking pot almost as big as M3D printer to make a spool holding compartment :-) work of genius ...

Too lazy to wash dishes by hand? Just 3d print a water powered DIY dishwasher machine!

Filip Sjoo from Sweden developed this ... this ... 3d printed washing contraption :-) !

Technically it is "worlds first fully functional 3d printed dishwasher" but I see it more as a example of 3d design skills since it takes some knowledge to put all those gears and water powered turbine to work together.





Now, it's a nice design and idea, but it looks like it uses a LOT of water since it needs a strong stream to power it. You would probably save some money by using your hands or standard washing machine.

Still ... great work Filip!

Now, if you want a functional dishwasher related scenario of use see how to repair a gasket with your 3d printer.

Repair fridge doors with 3d printed replacement hinges

Simone Fontana and Ricardo Salomao repaired a broken refrigerator doors with 3d printed hinges. Another success story for owning your own universal home fabricator :-) The replacement part was printed on Ultimaker 2.

It would be interesting to see how many openings can the plastic hinge survive. Probably not so many (I might be wrong since it is only turning the door on the axial pivot).

Like someone pointed out in the comments, the full metal replacement hinge can be bought for some 10 USD, but it can be argued that in the future 3d printing materials will improve and then the whole replacement parts industry and economics will drastically change.

A hobbyist also gains knowledge and independance by repairing his own stuff.

Also do keep in mind that there are many plastic parts that cost a lot and are not under heavy stress.

Tutorial on how to create molds for concrete objects with 3d printing

I'v been following HomeMadeModern for some time since they have some great DIY furniture projects with wood and concrete elements. Their design is very modern, minimalistic and easy to build.

In this project a better dish for dog food is built. It is curved and angled on one side so the dog can get all the food.
They use 3d printed full size prototype to create a mold and then poor the concrete mixture in.
The results look very good. You could use this technique to create any object in concrete, only limitiation would be the size of your printer.

If I catch some time in the future I'll try to build speaker housing made from concrete similar to P.A.C.O. open source project.

Great project! I like the idea of concrete furniture pieces, I don't have any experience with them, but even the concept seams better then those horrible IKEA pieces. And you can make them as unique as your own creativity.

3D printed NYLON permanent coffee filter

You can use nylon based filament to print functional permanent coffee machine filters or simple hot water filters. I'm not sure you could use PLA or ABS for it. Nylon is probably more heat stable and food safe with some water permeability properties. Here are some images of:
