Some nice industrial design and soundproofing make this a desktop CNC that could fit cleanly into a design office

Inventables has launched a luxurious looking new desktop CNC machine, Carvey, to the desktop market, grabbing our interest with its slick design by MNML, and new easy use software.

Once you’ve got past the horrendous marketing schtick about ‘3D carving being the new 3D printing’, it’s actually an interesting bit of kit at a decent price point - $1,999 via its KickStarter campaign.

It’ll cut through the usual array of materials, including wood, soft metals and plastics on its 12” x 8” x 2.75” cutting bed, but thanks to a clever case, manages to cut back the milling noise to something relatively acceptable to have in an office environment.

LimitState has unveiled its new STL fixer as a ‘one click automatic fix’ solution for professionals

Sheffield’s LimitState software has released its new application, LimitState:Fix, which sets out to simplify the process of preparing 3D models for printing in a professional services.

Although we’re used with seeing such tools for consumer printers being launched on an almost weekly basis, new tools for the professional that can rival Materialise Magic’s dominance of the market are seemingly on the rise.

LimitState has used MachineWorks’ Polygonica technology, providing a “one click automatic fix solution” for 3D STL files, closing solids, fixing polygon orientation, removing self-intersections and noise shells, and ensuring the geometry is manifold, enabling them to be printed.

Metals 3D printing: Power of laser melting allows new materials control on a micro level

Using an Arcam electron beam melting system researchers say they can control the variations in crystallographic orientation in a nickel-based alloy

While 3D printed metals are still metals, there’s a structural difference between them and the stuff you get cast in the traditional sense, which is still worrying some people about part strength and consistency.

Researchers at the US Department of Energy’s Oak Ridge National Laboratory (ORNL) have demonstrated an additive manufacturing method to control the structure and properties of metal components with precision that not only matches conventional manufacturing processes, but goes even further.

ORNL researchers have demonstrated the ability to precisely control the structure and properties of 3D printed metal parts on a micro level during formation.

A team from University of Wales TSD Swansea are looking to kite surf across the Bristol Channel

This weekend you’ve probably a friend, relative or colleague doing something, somewhere for a charity - a noble deed, some exhausting act, or something simply ‘a bit daft’.

We’re a society that thrives on both pushing ourselves, and contributing to helping others less fortunate, which is why the task set by a group from University of Wales TSD Swansea’s product design course is so eye catching.

Harnessing the power of both sea and wind, five kite-surfers will attempt to cross the 33 mile Bristol Channel in a world’s first attempt - To put this into context, the English Channel (Dover-Calais) is a mere 21 miles.

Aerospace: New fan blade design could mean 25% less fuel for Rolls Royce engines

The test flight is another step on the path towards entering service in 2020

The Rolls-Royce composite carbon/titanium (CTi) fan blade for its Advance and UltraFan eco engine designs has taken to the skies for the first time.

The lighter fan blades retain aerodynamic performance, which when combined with a composite engine casing reduces weight by up to 1,500lb per aircraft, the equivalent of carrying seven more passengers at no cost.

The Advance engine design will offer at least 20 per cent less fuel burn and CO₂ emissions than the first generation of Rolls-Royce Trent engine and could be ready for entry into service from 2020.

The first Haas Technical Education Centre (HTEC) in Africa has opened to students

The first Haas Technical Education Centre (HTEC) has opened in Casablanca, Morocco, at the Institute of Aeronautics and Airport Logistics (ISMALA), designed to offer training in CNC skills and competencies.

ISMALA is one of more than 300 similar resources in Morocco, created to prepare young people for work in growth sectors of the nation’s economy.

As its name suggests, the Casablanca facility was built specifically to provide training in aeronautical engineering and other, related subjects, with more than 100 of the world’s top aircraft and aeronautical parts manufacturers present in Morocco.

Water treatment system cleaning up due to SolidWorks

Using 3D CAD the engineering teams at Clear Stream Environmental have improved efficiency by 25 per cent - making more water drinkable

Water is important, but we don’t have much of it: With the earth covered by around 71 per cent water, 2.5 per cent is drinkable, with only one per cent easily accessible, the rest frozen in glaciers and ice fields.

Droughts and pollution don’t help this matter, although water treatment technology is constantly developing to meet this essential human need.

Clearstream Environmental has been challenging the usual development approaches as it aims to create future water treatment equipment, using its entire SolidWorks suite on the problem.
