Diode Lasers in Cladding, Additive and Hybrid Manufacturing

  • July 11th, 2017

By Oleg Raykis
Today there exist a number of technologies for additive manufacturing of components.
The two most prominent types utilizing lasers for generating parts out of metals are either powder bed based solutions or direct energy deposition, often referred to as laser metal deposition. As a company Laserline focuses mainly on the second type. Depending on the application it allows you to produce larger part sizes with higher productivity (deposition rates and therefore higher productivity) due to the fact of not being limited by the size of the building chamber as it would be in the case of a powder […]

Quality Assurance of Selective Laser Melting Applications

  • July 11th, 2017

By Thomas Gruenberger
Key differentiation criteria for Additive Manufacturing (AM) technologies are freedom of design, cost advantage, customization, and time to market.
Direct metal laser sintering (DMLS) AM technology is ideal for serial production for industries like aerospace.

Setting up a process means mapping the input parameters (e.g. machine and process parameters and part geometry) to output parameters (part properties like density, tightness, surface quality). An in-situ non-destructive measurement of part properties like density is not possible, so indirect measurements have to be performed. Information from the process – process emissions, melt pool size, melt pool dynamics, and temperature distribution – […]

Evolving Laser Safety Classification Concepts & New Products

  • July 7th, 2017

By Karl Schulmeister
The classification of lasers by the product’s manufacturer – from Class 1 to Class 4 – is a valuable means to provide the end user with simplified information about the potential hazards to the eye and skin.
The concept of product classification can be considered a success story. Developed in the USA by the CDRH in the 1970s, it has been accepted internationally for more than 30 years, based on the standard IEC 60825-1. While the basic system of classification has remained unchanged since its inception, some adjustments were necessary over the years and will also be necessary […]

Proposal of a New Laser Safety Guard Material & Its Protection Time Evaluation Method

  • July 6th, 2017

Thin metallic sheets made of aluminum or steel with a thickness of 1 to 2 mm are often used as laser guard materials. However, metallic laser guards are easily penetrated by high power laser irradiation due to quick melting.
Therefore, their protection times are short. Current problems of metallic laser guards are: (1) A tendency toward generating a large through hole due to quick melting if irradiated with high-power laser; (2) Protection times are significantly influenced by surface reflectivity conditions and reflectivity changes over time.

Contrary to ordinary metals, pitch-type carbon fibers have […]

Laser Safety in Entertainment Applications

  • June 23rd, 2017

By James Stewart, CLSO

High power lasers are routinely used in entertainment environments as a special lighting effect. Historically such lasers could only be used in situations where the budget, infrastructure, (namely power supply and cooling), and space permitted.
In recent years, however, these barriers have disappeared with the proliferation of low-cost solid-state laser light sources that now dominate this sector. This has created new opportunities in how the effects are being used, as well as who is able to now use them.

Business is healthy for the specialist laser effects providers that typically supply lasers for events and music performance tours, […]

Setting Up a Laser Lab? Avoid the Pitfalls

  • June 14th, 2017

By Jamie J. King, CLSO

The design of a laser laboratory is not only critical to its overall functionality, but more importantly to the safety of those who work in and around it.  The safe planning of a laboratory is no accident.  From conception to commissioning of the laser, safety must be involved in every step of the process.

Each situation presents unique challenges with equally differing solutions.  It is up to, and the responsibility of, the Laser Safety Officer (LSO) to ensure that each Laser Controlled Area (LCA) is fashioned in the safest way possible.  American National Standards Institute (ANSI) […]
