Three Hyper Cool 3D Printed Chairs

Here are three 3d printed chairs that look very futuristic and HYPER cool. They will probabyl find their place in some modern art gallery or in a tech billionaires mansion.

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.

Design thin PLA objects and make them strong in your oven

"CNC Kitchen" published this great video on how he designed gardening clips for his raspberries. He focuses on how to design thin-walled object in Fusion 360 and how to make it more weather resistant and stronger by annealing them in his oven.


Here is the video where you will learn a nice and easy design flow process and see several tools in action:

How to reduce rattling noise on your 3d printer

Tech2C, an Aussi 3d printing youtube, made this video where he shows how to eliminate and reduce the noise, vibration or rattling for his 3d printer.

He uses a HyperCube 3D Printer but his guide is applicable for almost any machine. Used upgrades are rubber feet, foam insulation, stepper motor dampeners or shock absorbers and TMC 2100 stepper drivers with stealthChop mode.






There is a great comment thread under that video with many additional ideas.

Amazing Laser Cut and 3D Printed Art by John Edmark

John Edmark creates the most amazing art pieces inspired by fractal geometry, spirals and natural organic shapes using laser cutting and 3d printing.





The laser cut movable tentacle gripper from plywood is something I would like to make...


The art of John Edmark is described in depth in this talk by Paul Dancstep:

SelfCAD is a new browser based CAD and slicer software

SelfCAD is a new browser based CAD and slicer application with many powerful features but focused on simplicity and usability. It has a subscription based model with a free trial and has a somewhat high cost for the benefit it provides.


Here is how SelfCAD is described:

SelfCAD 's mission is to make 3D designing and printing accessible to everyone, including professional designers, as well as hobbyists and students who have little to no prior expertise using CAD/CAM software. One of the greatest achievements of SelfCAD is its simplicity and a low entry price point. Advanced shapes can be created within minutes using various shape creators.

SelfCAD is an online browser-based CAD/CAM platform which allows the you to model, sculpt, slice and print online. With SelfCAD, you do not have to spend months learning complex software and pay hundreds of dollars for the privilege. SelfCAD is about simplicity, affordability and accessibility. Learn, create, and print objects in a fraction of the time required with traditional CAD/CAM software.

3D Printable DIY 600 Watt Halbach Array DC Motor

Christoph Laimer, well known for his 3d printable motor designs, developed a new and more powerful DC motor. It has 600 Watts of output power and performs with more than the 80% efficiency. The magnets of the rotor are arranged as a Halbach array and the motor runs with a standard ESC widely used in different RC applications (plane, drone, car etc.).

This project is a perfect example how you can use 3d printing for some ver powerful and practical printable objects. This is not just another fidget spinner, THIS ROCKS!!!

ESA 3D Prints Moondust Bricks for Space Colony Construction

Space colonies will be built with 3d printers. We will never see bricklayers and construction workers in space suits.





Technology description:

Bricks have been 3D printed out of simulated moondust using concentrated sunlight. This ESA project took place at the DLR German Aerospace Center facility in Cologne, with a 3D printer table attached to a solar furnace, baking successive 0.1 mm layers of moondust at a temperature of 1000°C. A 20 x 10 x 3 cm brick for building can be completed in around five hours.

DLR Cologne’s solar furnace has two working setups: as a baseline, it uses 147 curved mirror facets to focus either actual sunlight into a high temperature beam, employed to melt together the grains of regolith. But this mode is weather dependent, so a solar simulator was subsequently employed as well – based on an array of xenon lamps more typically found in cinema projectors.

Make Your Own Fixed Gear Electric Bike With 3D Printing

Tom Stanton developed a 3d printable system that converts a regular bicycle into an electric powered one. Biggest 3d printed parts are the motor mount and wheel pulley system.
He modified the "Vilano Rampage" fixed gear fixie single speed road bike. The motor used this project is the Turnigy Aerodrive SK3 - 6374-149kv brushless outrunner motor with 6s 5000mah li-po battery.

Marlin 1.1 released!!!

The new Marlin 1.1 firmware has been released with many new features and upgrades!

Here is the description from github site: Marlin 1.1 Release Notes

"Marlin 1.1 represents an evolutionary leap over Marlin 1.0.2. It is the result of over two years of effort by several volunteers around the world who have paid meticulous and sometimes obsessive attention to every detail. For this release, we focused on code quality, performance, stability, and overall user experience. Several new features have also been added, many of which require no extra hardware.

The code has been significantly optimized in several areas, leading to fewer stutters, better delta performance, more reliable USB/Serial communication, and more consistent and deterministic results."

Key improvements are:

• More consistent configuration with sanity-checking.
• Many more boards supported, with sane defaults for most common features. Improved thermal protection, enabled by default with tight margins for error.
• Improved Auto Bed Leveling with Bilinear Mesh and probeless operation.
• Unified Bed Leveling™ – Combining all forms of bed leveling in one package, plus tools like G26 Mesh Validation to improve leveling accuracy even further.
• Option to "fade" leveling compensation out over several layers to save computes on long prints.
• Support for up to 5 extruders with different geometries.
• Support for mixing and switching extruders. Linear Advance compensates for viscosity and pressure to reduce ooze and improve surfaces.
• Dozens of languages including Japanese, Galician, and Simplified Chinese.
• Significantly improved UI performance, especially Graphical Display.
• Display rate adjusts dynamically to prevent print stuttering.
• M600 Filament Change, Nozzle Clean, Nozzle Park, Auto Park on Pause, etc.
• Improved support for Bed Leveling probes and Manual Probing.
• Support for Trinamic steppers, i2c control, steppers as endstops.
• Endstops can use pin interrupts for improved performance.
• M43 Pins Debugging to report about, test, and monitor pins and endstops.
• Print Job Timer
• Sorted SD Card file listings.
• Improved host integration, extended capabilities report, keepalive messages, auto-report temperature, and more!
• Integrated I2C Bus allowing Marlin to interoperate on multiple boards.
• Support for Case Light, RGB LED, LED Strip. Printer events feedback.
• New features too numerous to list here. Read the config files for details!
