TRINUS The Affordable 2-in-1 3D Printer

Starting from the fact that most 3D printers under $500 experience technical failures after just few uses, a new powerful 3D printer has been launched to bridge the gap between affordability and professionalism, Trinus!

Trinus can be your 3D printer in a moment and your laser engraver the next one! The $299 2-in-1 printer is all metal, made of high-quality aluminum and steel parts in order to survive with the best performance ever. It also supports many types of filaments like PLA, ABS, PC, Flex, Wood and other materials available at the market.

Check out this video to learn more about Trinus:

Fortunately, you don’t have to spend a lot of time while assembling Trinus thanks to its 11 modular units that can be able to set up easily and quickly

This stable and accurate 3D printer is scaled down from industrial-grade machines giving it the ability to be durable.

“We were able to design a low-cost single-axis slide that delivers extremely high precision but keeps Trinus affordable. With all metal internal components, Trinus does not require constant recalibration. Its parts stay in place. Because it is so stable, Trinus maintains quality printing up to print speeds of 70 mm/sec, and is capable of running at a maximum speed of 150 mm/sec.”

Pause/change color, adjust speed and temperature, check elapsed time and percentage of completion are all accessible while operating thanks to the 3.2-inch LCD screen attached. Check this out in action.

Below are the specifications of each the printer and the laser engraver:

You can order your own TRINUS now at this link. A Kickstarter campaign was the way to market this printer and it had done a great job, $1,621,021 was pledged of $50,000 goal at the end of the campaign. Check it out the campaign to know more details.

New current sensors have no magnetic circuits

Clemens Valens @ elektormagazine.com discuss about LEM’s new current sensors which do not use the Hall effect make the measurement. Instead they integrate conductors for gradient measurement and provide immunity against the external fields. He writes:

Here are some new integrated circuit transducers for AC and DC isolated current measurement up to 300 KHz that offer full isolation, despite their small size, by integrating the primary conductor for nominal current measurements of up to 30 A. The transducers are mounted directly onto a printed circuit board as SO8 or SO16 SMT devices and support overload currents up to 200 A peak for short durations (1 ms).

Meet Obsidian, A $99 Plug & Print 3D Printer

Kodama Inc is a new company that delivers a new generation of FDM 3D printers that increase the possibility of affordable 3D printing. Recently, Kodama launched its new 3D printer “Obsidian“, the first 3D printer made for professional applications starting at under $100.

Most additive manufacturing machines in this price range are not aesthetically designed, nor engineered for accurate printing. Many consumers who are eager to upgrade their skills set are unable to because there is no affordable 3D printer that boasts high-quality printing.

“We wanted to create a 3D printer that defies what’s on the market. A sleek design, high-quality printing, and customizable, all starting at under $100,” said Michael Husmann, the ex-Apple employee and founder of Kodama Inc.

Obsidian is designed to deliver 3D printing functionality and features are more commonly found in devices that cost at least $1,000. It also can print in very high accuracy with a layer thicknesses between 50-350 microns. Obsidian’s design provides a stable printing experience, while the customized internal components decreases the need for frequent maintenance and recalibration.

Obsidian’s features include:

  • Printing volume: 120 x 120 x 120 mm
  • Printing Resolution: 50-micron at a steady 70mm/s speed
  • Plug and Play: Obsidian comes fully assembled, making it easy to get printing started in a few minutes.
  • Smart Display: Obsidian’s UI was tailor-made for Kodama by automobile UX designers to be inviting for beginners while packing all the controls a power user needs.
  • App Control: Obsidian’s Pro’s display runs on Android, allowing a myriad of new features. You’ll be able to remotely monitor and adjust your print settings while recording time lapses and receive prompts when your print is done or if something needs your attention.
  • Wide Filament Compatibility: Obsidian works with most filaments on the market, making it the ideal 3D printer to complete a variety of projects.
  • Heated Bed: Expands printing options by allowing the user to print with ABS, PETG, and other filament types. Only available with Obsidian PRO.
  • Exclusive Obsidian PLA: Obsidian is a naturally formed volcanic crystal. This filament contains real crushed Obsidian powder stones, and is only available through Kodama.
  • Camera: Record time lapses and monitor prints remotely.

Kodama is planning to launch a Kickstarter campaign in June 2017, and it will offer limited Early Bird deals at $49 for the basic version of Obsidian.

Last year, Kodama raised over $1.6 million for Trinus, an all-metal 2-in-1 3D printer and laser engraver for under $500. Successfully shipping their breakthrough product to over 3,100 backers in 80 countries helped solidify Kodama, Inc. as an up-and-coming leader in affordable, high-quality 3D printing.

Nixie Bargraph Kit

Robin @ kickstarter.com launched his new campaign on a project using IN-9 Nixie tubes. Now you can easily control two IN-9 Nixie bargraph tubes with 2 PWM inputs from your Arduino, Raspberry or other control board. The tubes are controlled by PWM signals and adjusting the PWM duty cycle you can control the tubes height, thay easy!

I had the idea for this project after building myself a Nixie bargraph clock which looked fantastic and eye catching. Instead of using conventional nixie tubes, which use numbers to display the time, the time is indicated by the height of the neon glow. But, this isn’t just limited to displaying the time, anything can be indicated with these tubes, temperature, humidity, atmospheric pressure, proximity… anything!
