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:

Mark Leonard developed a 3d printable broom you can use on your floor.

More detailed guide on how to do it with bridging code and other advanced bridging projects can be found at:!mg_ld=10864

Luckily we do have a dishwasher so I don't have to wash dishes by hand, but if you do you can always 3d print your dishwasher or 3d print a scrubber in antimicrobial Purement filament designed by Jake.

You can find all the files to print it at:

Happy cleaning! No, I'm just kidding ... I feel your hurt ...

Pentacopter drone with 3d printed parts

... just a cool and unusual DIY pentacopter drone design I wanted to share. It uses 3d printed parts in motor housings and probably other structural sections.

It will certainly draw some attention when it flies ...

Here is it flying in the night with LED strips:

Simple DIY sensor for nozzle clogging and print failure detection

Florian Maurer developed a DIY sensor to register nozzle clogging and print failure.

It is easy to make since it consists of a rotary encoder, some thin foam tape, and some 3D printed parts with Arduino used to listen to the grey code from the rotary encoder and send the data over serial to a Python script.

When the filament slows down or stops due to a nozzle clog, the Python script plays a notification sound to let you know that you should check your nozzle and that your print might fail.

Using natural materials to 3d print buildings

Here is an interesting presentation on using different materials like clay, rubber, paper, wood, salt and other for 3d printing of buildings and architectural elements. The presentation is held by Ronald Rael from Emerging Objects.

EasyWelder tool for welding filament pieces

EasyWelder is a tool that will enable you to weld and splice filament pieces together.

It is described by manufacturer as:
3D printers use as raw material plastic filament of about 360 m long, coiled. With a coil, we can make some items. But when there remain only a few meters, it is often impossible to use it. This filament is then unusable or discarded. Considering the price, it's infuriating.
It also happens that the filament breaks during printing or on the coil.
The current size of the filament coils do not allow to print large parts. The best solution would be to link together the filaments of each coil. Thus, the size of the printable parts would be no more limited.

From these findings, I have sought to develop a plastic filament welder to:
  • Print large parts.
  • Reduce filament waste.
  • Combine different colors and / or filament materials.
  • Making life easier for 3D printers.
  • Saving money.
The EasyWelder can weld the following plastic filaments:
  • PLA
  • PVA
  • ABS
  • HIPS
  • NinjaFlex and other similar filaments
  • PEG
  • Nylon

Here is how it works:

It is priced at 69-80 euro range. You decide if it's worth it. I wander if there are any DIY solutions? page:

Converting an old toolbox into a DIY 3d printer

Chad Bridgewater is a maker that uses old machines and converts them into 3d printers and other digital fabrication devices. They have a great retro style. See his previous work here, it is a must-study if you are a fan of more rough and raw retro design. 

Now he is converting an old metal toolbox into a custom 3d printer. I really like the look and convergence of old and modern. The box he uses is a Huot toolbox that was once used as a "Blower Repair Kit", the toolbox has a fold-down front panel door.

Here is a latest video presentation from video series showing each step of the process:

For detailed build log take a look at:

Another great project Chad!

5axismaker is next generation of desktop manufacturing machines

WOW! I really dig this concept of five axis multi-tool! It gives you 5 axis CNC machine that includes milling and 3d printing heads, touch probe, hot wire-cutter and a special mount for custom tools. This is probably a dawn of low cost multi-axis and multi-tool digital fabrication devices.

The company that is developing it also created open source Grasshopper script that allows programming of this 5-axis machine.

It was sold on pre-order from Kickstarter campaign for £4,499 (about $7000). The pack included:
Base 5axismaker: 5axis machine + 1 milling tool head + Set of Tools (Touch-probe, 3d printer, Wire-cutter, Adapter for other tools). 5axismaker cutting/making volume 400x400x400 mm.
I'm really looking foreward for developments in this field! Only 3 axes is sooo yesterday!

Here you can see a close-up video of conformal 3d printing in 5 axis:

Funbot Pro all-in-one DIY 3d printer

Cliff Mellangård, Swedish 3d printing guru and creator of excellent low cost Funbot 3d printer is developing an all-in-one DIY RepRap based on Raspberry Pi 2. It has a 7 inch LCD screen and when you connect external keyboard and mouse you have a full 3d printing workstation in one machine.

Here is the Funbot Pro presentation video:

Nice work Cliff! Files for it will be probably available soon since it is still in early development stages.


Here is the first real print of FunBot Pro with further details explained by Cliff:

How to smooth your 3d prints with epoxy

TechWizAu made a video describing how he uses epoxy to get a smoothing effect without using acetone.
He uses the Z-Poxy PT-39 30 Minute epoxy to get much smoother surface finish. It is a dual component epoxy with the resin and hardener.

Here is how to video with the entire process and some tips:

I was not aware of this technique and it looks much easier then using acetone. I'm not sure what epoxies are available on my local market in Croatia but I will check it out.
