New versions of GCodePrintr and GCodeSimulator Just Released!

3dprintapps.de just released a new version of their 3D printing apps GCodePrintr and GCodeSimulator.

Version v3.0 comes with many improvements and several new features, which will help to maximize the capabilities of your 3D printer.
GCodeSimulator App is the free sibling of the paid GCodePrintr App. Both together have been downloaded from Google Play more than 50000 times and are actively used by more than 6000 users.

The new version is available on Google Play now (staged rollout just started).
GCodePrintr on Google Play: https://play.google.com/store/apps/details?id=de.dietzm.gcodesimulatorprinter
GCodeSimulator on Google Play: https://play.google.com/store/apps/details?id=de.dietzm.gcodesimulator

Most important changes:

v3.0 comes with dual extruder support!

  • Dropdown list to quickly select an extruder
  • Show temperature for each extruder
  • 3D view colored by extruder
  • Calculate extrusion by extruder
  • and more

GCodePrintr v3.0 comes with several improvements to the UI interface:

  • Customizable button to quickly access your favorite macro.
  • Dialog to enter customer step size for manual movements
  • Dialog to control Fan speed (long press on Fan button)
  •  New status dislog to see status of printer connection, web interface, network receiver...

The web interfaces design has been refreshed and is now using a responsive web design. Additional functions added:

  • upload gcode through the web interface and start a print remotely.
  • use the build-in camera to show a picture of the print
  • manual axis movement and homing  
  • and more   

Extend the list of supported 3D printers and printer electronics:

  • New printers added to supported list (e.g. Tevo Tornado)
  • Better print time estimation by taking M201 acceleration into account
  • Add fallback for unsupported USB devices (e.g. unknown VendorID)
  • Send line numbers and checksum to the printer  
  • Gbrl improvements

Many usability improvements (e.g. new help dialogs) to simplify the 1st time use of the App.

Water Cooled E3D Titan Aqua Hot End

E3D just presented their water-cooled hot end: the Titan Aqua. The primary usage scenario for the water-cooled hot end is in 3D printers that have heated chamber or passively heated enclosures.

3D Printed DIY Arrowheads by Juleah

Making your own archery equipment is one of the essential skills any archer should master. Here is a cool and useful DIY project made by Juleah, where she used a 3d printer to make printable arrowheads or field points.

Here you can see two videos detailing the entire target testing and improvement process:

The final version of horizontally printed points is strong enough to go through soft hay targets.

You can find out more about Juleah and her work at:


STLs for the field points can be downloaded via the LBRY.io application:


(LBRY is for the users who prefer open-source decentralized content distribution)

Or, if you prefer corporate controlled site, on Thingiverse:

Decentralize your DIY projects with LBRY

If you consider yourself a part of DIY or 3D printing community, you most certainly regularly look at other peoples projects or publish your own work on some platform like YouTube, Thingiverse or Instructables. There is an incredible amount of knowledge and value being contributed by users every day - but do they get the fair amount of value back from those platforms?

Since all of the biggest platforms are privately owned, what would happen if those companies decided to close them for any reason destroying all the content in the process? Or decided to charge you a fee for publishing your content or decided to remove your content for some arbitrary reason ... or got hacked ... there are many very negative outcome scenarios since there is too much power accumulated within a single point of failure. Currently, many YouTube creators in DIY space are faced with random demonetization and there have been major problems with Thingiverse in the past.

Is there an alternative? Looks like there is! It is a decentralized, open-sourced blockchain based system named LBRY (Library). With LBRY there is no middleman.

LBRY is best described as a content platform (YouTube or Thingiverse) that works similar to a BitTorrent network where each user downloads and re-publishes the content he viewed.

You can read the full description here:


Or watch this short description video:

LBRY is currently a great platform for video creators who want to increase their reach, secure their presence, improve monetization and are not satisfied with YouTube policies and uncertainty due to demonetization or censorship. If you are an existing YT creator, there is a simple YT import procedure you can find here:


The application interface is simple and easy to use, here is a short overview by Wayne Beach:

In the future, there will also be a mobile app available.

LBRY is not only for video, you can also publish all your project files, code or any other digital format on the Library app. LBRY is open sourced, so it can be used in a variety of roles as a specialized platform. One current implementation is spee.ch website which "takes" the content from the LBRY chain and acts as a decentralized image hosting site. Any developer could use the technology and develop a web browser accessible Thingiverse alternative for 3d printing files.

Publishing .STL files is very easy, just click on the green "Publish" icon in top right corner:

Your content can be monetized with LBRY credits cryptocurrency or you can receive tips for your work. LBRY crypto can be exchanged on many exchanges for Bitcoin or the regular money.

Do keep in mind that LBRY is still under development with a constant stream of new improvements and features being added. I know that most of you are more than capable of using this type of software and even give some feedback to the developers to make it even better.

Now go and give LBRY a test run to distribute that great content you made!!! Sharing is caring!


For more in-depth insight, have a look at this interview with LBRY CEO Jeremy Kauffman by Bryan Lunduke:

3D Printed Military Submersible

Engineers in ORNL made military’s first 3D-printed 30 feet long submersible hull made from carbon fiber composite material.
The Optionally Manned Technology Demonstrator is a prototype vessel that could be used to deploy divers, logistics capabilities, and sensors. It was made much cheaper and faster when compared with traditional manufacturing methods.

We don't need more weapons guys. We need more technology for permanent peace.

Two Great Surface Finishing Tutorials

I was researching YouTube to find some good surface finishing, smoothing and painting tutorials, here are the two good ones I found.

First one is from Jure Korber from Slovenia. He made this detailed tutorial and has some good tips like the using of wooden stick to hold the piece.

Second is from Commando Designs

Hopefully, you found them useful!
