“Power Machines” Preparing Prototype of GTE-65.1 Gas Turbine with 3D Printed Parts

Top 3D Shop corporate blog 3D printers

PJSC Power Machines has started to create a model 16-stage compressor and a prototype combustion chamber of the GTE-65.1 gas turbine. The combustion chamber will be manufactured using 3D printing technologies. Inspection can be completed with the use of laser 3D scanning (see examples here).

Pozvonoq Startup to Launch Mass Production of 3D Printed Intervertebral Cages in 2022

Top 3D Shop corporate blog 3D printers

The use of 3D printing in medicine has long ceased to be limited to materials such as PEEK (more on PEEK 3D printing here). The Pozvonoq startup of the North-West Technology Transfer Center and the Russian manufacturing company Ortoinvest has begun laboratory tests of ten lines of intervertebral cages designed to stabilize the spinal column. The successful conduct of technical expertise and the receipt of a single registration certificate will allow the serial production of medical devices as early as 2022.

Reverse DevOps, an invitation to project «Bell»

Self Promo

Typical DevOps handles code deploys in a single direction: from Dev to PROD, from lower environments to higher environments, and for this there are many well known solutions like Jenkins, Terraform, Octopus. But in the opposite direction the situation is not so good.

Yes, in many companies there are home-grown processes to copy databases from higher environments to the lower ones (with hiding/removing sensitive data) to reproduce problems, found on PROD. However, in complex scenarios an access to PROD is needed to find the root cause. Developers need at least logs. And in the Enterprise world it's all depend on the level of paranoya how sensitie the information is.

Thi is what we suggest, the project is to create a safe access method to the higher environments, combining easy friendly interface and interactivity with the full audit of all operations and controlled manner of what users can do and what they can't. The project is called Bell -Action at a distance, and a bearded guy on the logo is John Steward Bell, you know him if you had ever heard about the Quantum Entanglement.

Kernel Queue: The Complete Guide On The Most Essential Technology For High-Performance I/O

High performance *System Programming *C *Development for Linux *
Tutorial

When talking about high-performance software we probably think of server software (such as nginx) which processes millions requests from thousands clients in parallel. Surely, what makes server software work so fast is high-end CPU running with huge amount of memory and a very fast network link. But even then, the software must utilize these hardware resources at maximum efficiency level, otherwise it will end up wasting the most of the valuable CPU power for unnecessary kernel-user context switching or while waiting for slow I/O operations to complete.

Thankfully, the Operating Systems have a solution to this problem, and it's called kernel event queue. Server software and OS kernel use this mechanism together to achieve minimum latency and maximum scalability (when serving a very large number of clients in parallel). In this article we are going to talk about FreeBSD, macOS and kqueue, Linux and epoll, Windows and I/O Completion Ports. They all have their similarities and differences which we're going to discuss here. The goal of this article is for you to understand the whole mechanism behind kernel queues and to understand how to work with each API.

How Accurate is the CALIBRY MINI?

Top 3D Shop corporate blog 3D printers

This article will cover how the accuracy tests of the Calibry Mini were conducted. 

The Calibry Mini by Thor3D is stated to feature an accuracy of up to 0.07 mm (0.0027 inch). What exactly does this mean? This means that under the normal conditions, the deviation in measurements of any single point can be 70 microns in any direction. This doesn’t mean that the deviation will always be 70 microns. It can be smaller, it can be bigger. The number is approximate and can vary depending on several factors that will be mentioned in the article.
