IS PLASMA THE MISSING LINK IN ASSEMBLING 3D PRINTED PARTS?

UMAIR IFTIKHAR

Creabis, a Kirchheim-based 3D printing service bureau, is using Relyon Plasma’s piezobrush PZ2, a handheld cold plasma device, to bond 3D printed parts.

The piezobrush PZ2 uses plasma to activate surface particles of a substance which strengthens the adhesion between joined parts. With a strong bond between assembled 3D printed parts, it is possible to manufacture large-sized sturdy components on small sized 3D printers. 

According to the CEO of Creabis, Ralf Deuke, plasma-aided bonding will lead to more novel applications in 3D printing.

Make a Portable Computer Using a Raspberry PiTylerJohnson

Have you ever wanted a portable computer you can take with you? This is the easiest way to build your own. For those of you who do not know what a Raspberry Pi is, it is a complete computer about the size of deck of cards that can run many different kinds of Linux. This portable computer will be complete with a screen, keyboard, wifi, and a battery. This is just to show how to make the components work on battery, this indestructible does not have instructions for building a case. There are a lot of interesting ideas for cases and I did want to limit anyone's options. I tried to find the easiest way of making a portable all in one battery powered computer.
For this project you will need to be comfortable doing electrical soldering and desoldering; if you are have not done electrical soldering before, there are many tutorials online.

CNC Router Rotary Axis

mkmra2

My router was a 3-axis machine. Adding a 4th rotary axis allows considerably more flexibility as the part to be machined can be rotated to expose different faces for cutting. I'd previously done some 4-axis router work at Stamps School of Art & Design - here's that post. I really wanted to add this capability to my router.

After exploring a few options - most of which were very expensive - I chose to go with an inexpensive kit from China. It was only $358 including shipping. I'd have to figure out how to get it hooked in to the electronics then build my own mount.

Um Modelo de Motor Radial de 7 Cilindros!

E sem complicações de montagem, por isso, de que estão à espera?

[Project] 7-axis Hand-Cranked Radial Engine ModelMika Yeap 

Hand-cranked and fully functional, this is a model of a seven-cylinder radial engine by plusalphaDesigns. It’s a “reciprocating type internal combustion engine configuration in which the cylinders ‘radiate’ outward from a central crankcase like the spokes of a wheel,” according to Wikipedia.
It’s a relatively painless model to assemble and print, requiring just a handful of plastic parts – you don’t even need any fasteners. So let’s jump right in!

Convert a 3D PRINTER to LASER ENGRAVER | Under 40$Jakes

- To start this project we are gonna need a laser that is strong enough to burn into most of the household materials. I found that 500 mw laser is just right for this project due to its low price and capability of engraving in almost every material with exception of metals and glass.
-I bought my laser on Aliexpress for a small price. Here is the link: https://goo.gl/obFmFD
-With laser you will also get a laser driver circuit and a safety glasses which are necessarry when operating with lasers.

Build Your Own 3d Printer Filament Factory (Filament Extruder)ianmcmill

UPDATE: Now with wiring diagram !
Long read:
3D printers are cool and they finally start to drop in price. Kickstarter campaigns like the one from QB-UP or M3D are popping up and they are finally "affordable". And with affordable I mean affordable like 200 $ and not "affordable" like 2.199$ affordable. However, once you are a proud owner of a 3D printer you will soon realize that your wallet is far from being let alone. No ! You need plastic filament of course to print those super awesome coat hooks and wheel chocks. Since the price for these filaments tend to top the actual material costs, printing before mentioned life savers is kind of expensive and could become a problem to the development of the ever growing 3D printer community
BUT FEAR NO MORE !! Some clever gents came along - Hugh Lyman with his Lyman Extruder may be mentioned here or the guys over at Filastruder.com - and saved the day ! YAY. And there was much rejoicing ! They have built plastic extruders everyone can build or buy at a decent price. However if you are a fellow Instructable.com user the first thing that should come to your mind is "I can build this by myself...and cheaper...". Building at lower costs is the nature of DIY after all.

Dito de outra maneira, CNC para o Povo!

Evezor: Open Source SCARA Robot ArmJeremy S. Cook

Per this project’s Kickstarter video seen below, when 3D printing first jumped came into the mainstream, many people thought they could now make anything they wanted, perhaps even many of them to sell with no human interaction. While true in some sense, these machines do require human intervention between prints, and can take a very long time to produce useful parts. Additionally, some designs may require a different tool, such as a laser cutter or CNC router. That, of course, means more space and money, and still there is the issue of machine tending.

SCAD to STL – How to Convert SCAD Files to STLBenjamin Goldschmidt 

SCAD and STL files are two common file types for 3D design applications. SCAD stands for “Solid Computer Aided Design”, and the file format is used to describe 3D objects. It was pioneered by a software called “OpenSCAD,” which is a free CAD software for designing 3D objects. STL stands for “stereolithography” and is a popular file type to use with slicers for 3D printing.
The main difference between these two file types is in the way the models are described in code. In STL files, the 3D model is created using a “tiled” set of triangles along the surface of the object. This creates a fully 3D object. In contrast, SCAD files design an object using mathematical relationships. For example, a cube-like object can be described using its length, width, and height. This type of design can be useful for printing objects such as fractal art on objects.
Because the geometry used by STL files is more capable of conforming to complex designs, you may find you want to convert SCAD to STL. Lucky for you, there are two really easy ways to do this.
