Iro3d 3D Prints in Powdered Metal

Hack a Day - Mon, 01/15/2018 - 16:00

Printing with plastic and even resin is getting fairly common. Metal printing, though, is still in the realm of the exotic. A company called Iro3D is aiming to change that with a steel printer that you can buy in beta for about $5000. That seems steep when you can get plastic printers for under $200, but it is sheer bargain basement for something that can print in real metal.

Of course, there’s a catch. The printer doesn’t create a solid metal object right away. What it does is prepares a crucible using sand and metal powder. You then place the crucible in a kiln and what comes out is the final product. You can see a video review of their prototype machine, below from [3D Printing Nerd]. The company’s promotional video that shows a part coming out of the kiln is also below.

In some ways, the printer is not as complex as a conventional plastic printer. There are no hot ends, fans, or heated beds to worry about. The head picks up a container of material and uses an auger to deposit it. There are two granularities of metal powder — one fine for visible surfaces and another for interior fill. There are similarly two containers of sand. The sand is like support material, and holds the object until it solidifies.

According to Iro3D’s website, the powders cost about $5 a pound and the machine can do 0.3mm layers. The “pourer” — we assume that’s the analog to a hot end — is 1mm in diameter. There is one catch if you want to buy one. They are only selling them in the Seattle area for now.

Looking at the machine it doesn’t look like it would be terribly hard to replicate with pretty standard 3D printing gear, especially if you already have an auger set up for paste extrusion. We’re sure the devil is in the details, but we are betting if this catches on we will see some homebrew attempts.

We’ve lamented about reasonable metal printers before. The only problem with this one is that if you have to have the kiln anyway, it might be just as easy to do lost PLA casting.

Is That Part A Counterfeit? Here Are A Few Pointers

Hack a Day - Mon, 01/15/2018 - 14:30

If you order an electronic component, how do you know what it is you are receiving? It has the right package and markings, but have you got the real thing from the original manufacturer or have you got an inferior counterfeit? We hear so much about counterfeit parts, and sometimes the level of effort put in by the fraudsters is so high that from either a visual or electrical standpoint they can be hard to spot.

[Robb Hammond] writes for Aeri, with an extremely interesting guide to some of the cues for spotting a counterfeit semiconductor part. In doing so he gives us something of an insight into the techniques used by the fraudsters.

The first feature of a package to be examined are the indents. Relabeled chips often have their old markings sanded off and a coating applied to simulate the surface of an unmolested chip, and this coating can either obliterate or partially fill any indentations. Using comparison photos we are shown discernable hidden indents, and partially filled indents.

We’re shown textures and paints, and how markings can sometimes be shown as counterfeit by washing with solvent. A Cypress-marked part is found to be a cheaper Altera one under the paint, and other parts are shown with misaligned markings and markings placed over indents. Wildly varying countries of origin are claimed while seemingly retaining the same batch codes, an impossibility confirmed by manufacturers.

If you order your parts from legitimate distributors then it’s likely that what you receive will be the genuine article. However with the popularity of online auction sites and online bazaars the possibility has become ever more likely of being left with a counterfeit. Knowing some of these tips might just make the difference between the success or failure of your work, so it’s an interesting read.
