Selective Laser Sintering (SLS) is the second most commonly used process after Stereolithography (SLA). SLS parts can be produced with high functionality in very short lead times.
Plunkett Associates have been pioneering this process over the last 20 years and have the experience and knowledge to guide you through your process options.
We know that by selecting SLS models, whilst accuracy and surface finish are not as good, the real benefit is the functionality that can be achieved.
Working with nylon, (or a filled nylon), SLS parts demonstrate a level of toughness that even permits on board usage in today's Formula One cars. This functionality is also behind the success that Selective Laser Sintering has achieved in Rapid Manufacturing.
Whilst the process is faster than Stereolithography (SLA), there is a requirement for an appreciable cool down period post build. This is due to the process operating close to 180 degrees Centigrade, and it is vitally important that SLS models are allowed to cool naturally. Trying to improve delivery times by short cutting the cool down process inevitably results in component distortion.
Whilst deliveries are always tailored to customer requirements, a typical turnaround would be 5 – 7 days, however small projects can be faster.
It is also worth noting that whilst the standard SLS materials (nylon or glass filled nylon) are white and provide durable, rigid and stable parts, sometimes you might need something a little bit tougher or a little more flexible – or even in black. The good news is there are options for these and Plunkett Associates can deliver both!

"There's a reason why I encourage my team and others to connect with Plunkett Associates...,Tim Plunkett. I've enjoyed the conversations and advice with you Tim. Your enthusiasm has no bounds. Such passion for the technologies and providing solutions for customers."Alan Bale Mechanical Engineering Technical Manager, Philips Remote Diagnostic Technologies Limited
"Always a pleasure to deal with. Hope the growth continues, Tim."Stephen Cooper Director Plastiserve Limited
Plunkett Associates worked on the design and production of titanium frames for an artificial heart valve where precision and consistency was paramount. Communications were efficient and productive with concepts readily incorporated into the final design, and suggestions for improvements all highly appropriate. The quality of the end product was ideal and I have no doubt that I will use the advice and expertise of Plunkett Associates again.David Wheatley, Wheatley Research Ltd

Thanks for the present that arrived this morning, as promised. Parts look first class, as always.
Plunketts developed a solution that met our precision requirements at a cost significantly lower than alternative manufacturing approaches we had investigated
Interestingly, people who look at it in its own right with little knowledge of what it does, just like it! It’s tactile and it looks good…
To create such a consistent quality finish in chrome was an amazing achievement and the prototypes really gave our stand the wow factor.
I can’t recommend Tim and his team highly enough. We ended up with a design which can be produced and assembled quickly, efficiently and reliably, in volumes that make sense
Kirintec were thrilled with Plunketts. They made a complex process simple and we were just amazed at the lead times achieved. Plus, every single deadline was met without any drama.
Plunkett Associates truly offer a complete turnkey solution with Speed, Effectiveness and Precision.
Plunkett Associates have a fantastic supply chain, work with all sorts of production processes and will always do their utmost to solve a problem.
We always know exactly what we’re getting and we know we won’t be let down on quality, price or lead times.
"With their simple to understand language, willingness to go the extra mile and approachability, Plunkett Associates were a great partner for our company. We couldn’t be happier with the results of our project. (A working prototype that they got right first time, by the way). Thank you!"
“We use Plunkett Associates because we want someone we can trust, that knows what they’re talking about, has all the contacts, will provide reliable advice and feedback and will get the right result for us.”
“Accuracy, finish and delivery all first class.”
"Tim's experience, expertise and supplier base have been fundamental to us getting this project off the ground."
