Direct Metal Laser Sintering (DMLS)


DMLS is a 3d printing process that can be used to create fully functional complex metal components. It achieves this by sintering together layers of metal powder to give parts with density as high as 99.9%.
At LPE we offer production and prototype parts. We offer a complete metal sintering service offering in- house metallurgy, stress relieving, EDM, bead blasting and 5-axis post machining to tight tolerances. We have developed qualification routes for AM production components, and have been actively involved in R&D in this field for several years with Universities and two Aerospace partners to ensure this process stands up to the rigours of the Aerospace and Medical industry.
We are continuing are research with Universities and industry and currently support 4 PHD students and 4 post docs with their research in advanced process control and powder development for metal laser sintering.

Metal Rapid Prototyping
Metal sintering is an excellent process for producing fast accurate metal prototypes, we have both high resolution (as small as 0.015mm) and production standard resolution (0.06mm) to cater for our different customers demands.


“Very good service with excellent part and delivery finish”


DMLS production
We offer a complete contract manufacturing service and qualification route, that we have developed in conjunction with the standards ASTM/ISO F3301 and FF3302.

• Process control documents (PCD),
• Powder certification and analysis (batch control, size distribution and chemical analysis)
• Machine certification (calibration certified, in-build laser power monitoring.)
• Quality reports from each build
• Mechanical testing
• Physical analysis , including porosity and density, surface and dimensional analysis.
• Heat treatments certification (Reports from our fully instrumented in house inert gas box furnace)
• Advanced Heat treatment certification , Hot isotonic pressing (HIP) (Fully cycle reporting from certified heat treatment facility, customised cycles available)





A recent addition to the LPE service range. we currently offer Metal Sintering in Stainless Steel, Hardening Stainless SteelAluminium and Titanium

At LPE we continually strive to offer our customers the widest range of materials and services, we will be expanding our Metal Sintering material range in the coming months. Once new materials are available we will update our website with further information, to find out more contact our sales team on 028 9070 6940

Finishes & Treatments

Metal Sintering produces components in recognised engineering metals suitable for a wide range of post production processing including;


      • Heat Treatments and Stress Relieving
      • Machining
      • Welding
      • Tapping
      • Polishing and
      • Plating



Providing 99.99% dense components, Metal Sintering parts built in Aluminium, Stainless Steel and Titanium offer a direct replacement for traditional machined components in Aluminium, Stainless Steel and Titanium and replicate almost identical mechanical properties.

The metal sintering process has proven popular for;


      • High Temperature Applications
      • Medical Devices
      • Dental Devices
      • Aerospace Components
      • Acid & Corrosion Resistant Prototypes
      • Plant Engineering components and
      • Tooling Inserts for Plastic Moulding & Die Casting.


Why LPE?

Short Lead Times:

Typical lead times for Metal Sintering is 3-6 working days unless otherwise stated.

Tight Tolerances:

Metal sintering offers an expected tolerance of +/-0.1mm to +/-0.2mm +0.005mm/mm*

Expert, Impartial Advice: 

As the first rapid prototyping bureau in the UK and Ireland, LPE has over 25 years experience converting customers designs into fully functional prototype components and with a wide range of services available, we offer impartial advise tailored to your individual project requirements.

Committed to Customer Service: 

An ISO 9001 & 13485 approved supplier, LPE consistently work towards excellence of both part quality and customer service. We endeavour to provide a fast, professional response to all customer enquiries and carefully monitor quality throughout the production process.

Rapid Delivery: 

LPE work with local couriers to offer free Next Day Delivery on all orders. For time sensitive projects speak to the sales team about A.M. and Saturday delivery.
