Desktop Metal 3D Printing with Microwave Enhanced Sintering

Here is another revolutionary step forward in 3D printing: the desktop metal 3d printer. It deposits metal "paste" made from metal powder with a polymer binder in a similar way as any common FDM machine and the parts are then sintered in a microwave enhanced furnace chamber.
The price is comparable to higher-end professional FDM machine from a few years ago. They also sell production cell that has much higher capacity for more demanding production facilities.


Tech specs:

  •  Build volume: 12 in x 8 in x 8 in (305 mm x 205 mm x 205 mm)
  •  Materials:  Steel, Titanium, Aluminum, Copper and other undisclosed materials
  •  Layer height: 50 μm (minimum)
  •  Dimensions: 60 in x 49 in x 30 in (1500 mm x 1250 mm x 750 mm)
  •  Technology: Microwave Enhanced Sintering
  •  Price: $120,000 for the desktop version, $250,000+ for manufacturing cell production system

New DIY CO2 Laser Cutter Project

Here is a new DIY CO2 laser cutter project from Instructables. It was developed by Michiel Deschout and uses relatively available materials and parts like 3030 aluminum T-slot profiles, Arduino and some 3d printed parts. The total cost was some 1900 Euro.
The presented setup uses 40W laser, but the power could probably be increased.






Very detailed step-by-step build guide with all the files can be found at:

https://www.instructables.com/id/Make-Your-Own-High-Quality-CO2-Lasercutter-With-To/



Here is the back side with 3d printed holders for the CO2 laser tube:


The latest fashion trend for all you 3d printing geeks

If you are into 3d printing then this is THE style of jacket you should wear!









































Detailed project description:

This jacket has 40 neopixels sewn to the back to display the status of the 40 3D Printers in Duke’s Innovation Co-Lab Studio. Each light corresponds to one printer and is either blue (in use), green (available), or red (offline) to show the real-time status of the printer. The printer status is retrieved via Duke’s Innovation Co-Lab’s 3D printer status API, documented here: http://apidocs.colab.duke.edu/.

3D Printable Parametric Slew Bearings

Christoph Laimer published  another very useful project. He developed a fully 3D printable and working parametric slew bearings. Since they are developed to be sturdy they can be used in many different project where a simpler 3D printed ball bearing would fail.
Since the design is parametric, you can adapt it to fit your needs. One version even has conical bearings.



























Project description:
Ball-bearings are very popular for 3d-printing. However they often fail for real applications. Using Fusion 360 I've created a parametric design of a "Crossed Roller Slew Bearing". The result is a pretty accurate and robust bearing. The bearing including the rollers is 3d-printed in separate parts. There are a few screws needed to clamp the two halves of the inner race together.

THERO project

THERO is a privacy project developed by Román Torre and Ángeles Angulo, that uses a Raspberry Pi with TOR routing. By moving the front panel you change your connection to the external Internet and your privacy.
It uses 3d printing to make the full enclosure and mold for the concrete encased version.


Here are two videos showing how the project was developed:

PrusaControl - a new software interface from Prusa3D

Prusa released a new software aimed at beginners: the PrusaControl, which is a simplified interface for Slic3r Prusa Edition.

Here is the description from the news release:
PrusaControl is an alternative user interface for Slic3r Prusa Edition.
Slic3r Prusa Edition was the first step with a great success and we are extremely proud when people mention they switched back from S3D. But Slic3r has one problem, it is rather complex and intimidating for new users. We cannot do much about this, it is its nature. And that is why PrusaControl was born. It is parallel to Slic3r PE for newcomers to 3D printing, we distil the settings down for the user and put our knowledge to the backend to get the same results. The main goal is to open an object and hit print. PrusaControl is simple, novice friendly and smart.

Formlabs Fuse 1 Desktop SLS 3D Printer

Formlabs just released their Fuse 1 3D printer which is a desktop selective laser sintering machine priced at 9,999 USD. It has a 165 x 165 x 320 mm build volume and uses nylon powder.

This is a small revolution on the market and a big step forward in 3D printing availability and affordability!!! Laser sintering machines used to cost in hundreds of thousands and were very large. This will push the competition to respond and lower the prices even more in the future.

Here is a different promotional "The Human Touch" video:

Here you can see the Fuse 1 size on a table next to a Form 2 SLA machine:



I wonder what will the price of the powder material be? Will it be recyclable and reusable? Will it come in proprietary cartridges with chip control unit?

ViaCAD by Punch!CAD

I'm always on a search for the new and interesting software tools and when I received a tweet from Punch!CAD about their ViaCAD product I decided to take a look.

ViaCAD looks like an easy to use CAD that has an acceptable learning curve and feature set. You can start from the easy models and move into more complex stuff as you learn. Since it has support for many file formats I was able to open and edit things from various sources. The community behind it and support/tutorials available helped me find answers quickly.

The price seems very affordable and there are no additional fees or vendor lock-in features. It runs both on Windows and Mac machines.


ViaCAD has some powerful 3D printing features and tools:

  • 3D Print Check: This tool checks a part for print viability, displaying warnings or errors to the user.
  • Surface Normals Check: Facet normals define the inside and outside areas of a part. If facet normals are pointing the wrong way, the 3D printer may have problems creating the part. If you have a normals issue, there are several commands that can help you fix this problem.
  • Overhang Analysis: The Overhang Analysis tool provides a means to visually inspect modeling areas that may require structural support for 3D printing. Meshes, surfaces, and solids facets normals are compared to the work plane direction. Angles that are less or equal to 45 degrees are highlighted as red.
  • Wall Thickness: The Wall Thickness Analysis tool provides a means to visually inspect modeling areas that may be too thin for 3D printing. Meshes, surfaces, and solids facets are examined using ray intersections. 
  • Preview Slices: The Preview Slices tool provides a user interface to slice models given a direction and thickness. The dialog box allows for animation through the slices and single stepping. One use of the Preview Slice tool is to verify a part has closed, non-overlapping sections, a requirement for 3D printing. The Save Slices option provides several options to save slices to DXF, STL or adds the results directly into your drawing.
  • Auto Position: The Auto Position tool translates the model to the positive x, y coordinate system at z=0.
  • Support Structure: Manually adds geometry to support material as it is created by the 3D printer. Support structures controls, include Attach Radius, Midpoint Radius, Base Radius, Base Thickness and Drag base and midpoints to modify structure location.
  • Show Printer Volume: Toggles the boundary of the default 3D Printer. The volume is defined within the Printer Definitions dialog box.
  • Printer Definitions: Sets key parameters of the 3D printer, including length, width, and height of the volume accessible by the printer. The parameters in the Printer Definitions dialog box are used for commands such as 3D Print Check and Auto Position.

In the future, I'm going to explore ViaCAd further and see if it can bring a CAD noob like myself on to the next skill level.
