Additive Layer Manufacturing (ALM) has been around for some time.  I got involved with this industry almost 20 years ago when it was called Rapid Prototyping and then 3D Printing and now ALM.  ALM builds structures layer by layer which is different than traditional manufacturing methods which either starts with a shape and machines away the excess or uses tooling to form a part to net shape. Some ALM processes rely on lasers to cure or solidify the material and others deposit the material through tiny nozzles but all methods build up a part in thin layers.

It has been a great technology for creating prototypes but has had little application in making production parts.  New methods and new materials have emerged more recently that may be able to make ALM more relevant to production applications. A good article appeared recently in Technology Review that discusses some of the current and future applications of the technology.   Altair recently had an ALM panel at our European Altair Technology Conference where leaders from the industry discussed the technology and its applications.

CAFE standards for model year 2017 have automakers looking towards lightweight materials to help meet automotive fuel economy benchmarks.

Prior to model year 2011, all manufacturer vehicle fleets needed to meet the same basic fuel economy targets: 27.5 mpg for passenger cars and 23.5 mpg for light trucks.  To meet fuel economy CAFE standards for a particular model year, manufacturers would often offset the sales of less fuel efficient vehicles with smaller fuel efficient vehicles. This has led to the belief that any increase in CAFE requirements would result in the demise of larger vehicles.

Many studies on automotive mass reduction have been undertaken over the years by various steel, aluminum, magnesium, and composites consortia, all expounding the virtues of substituting a particular material. Altair has participated in studies with all these organizations over the years and has understood the strengths, limitations, and constraints of working with various materials.

 

AHSS, HSS, Al, Mg, Ti, GFRP, CFRP…

High Strength Steels, Aluminum, and Magnesium all have certain advantages in specific applications. Understanding when to exploit the unique advantages of these materials while concurrently minimizing the associated cost penalty is key in any weight reduction challenge. Read More

Advancing Composites in the Auto Industry

, Vice President, Global Automotive

This post was taken from Altair Enlighten.

In my new role as Altair’s Vice President of Global Automotive, I look forward to sharing automotive trends and news with you. To kick off my posts, I wanted to provide my insights on advancing composites in the auto industry by answering some of the most important questions about Altair’s role in the use of composites for today’s vehicles.


Success in developing the new generation of cars and trucks has demanded advancements in many arenas, including powertrains, fuels, materials, manufacturing methods and design. Computer-aided engineering tools from Altair have advanced as well allowing design engineers to improve vehicle efficiency and performance while at the same time lightening the vehicle structure.

Last week, the North American International Auto Show kicked off in Detroit’s newly renovated COBO Center with press and industry preview days before opening the show to the public last weekend. For me, it’s easy to see how simulation technology played a role in the impressive end results for the vehicles exhibited across the show floor. However, that might not be the first thing that comes to mind when you’re staring face-to-face with a stunning concept car.

Lightweight design, performance, fuel efficiency standards, carbon emissions and vehicle safety all will continue to be topics discussed among the many engineers, analysts, automotive enthusiasts and other show attendees. Simulation technology will be inherently present within some of the most impressive products on the show floor. Read More
