DLP – Digital Light Processing
Digital Light Processing (DLP) – parts produced fast in production grade materials.
Digital Light Processing (DLP), one of the newer Rapid Prototyping processes, offers ultra fast print speeds and new material chemistries that resemble production grade materials.
The DLP process uses a digital -projection light source to cure the surface of a liquid photopolymer. This process is particularly suited to parts with complex structures with small cross sectional areas that require good surface finish and high strength properties. For further information visit the DLP Process page.
As the first service bureau in the UK offering parts produced using a Figure Four machine and with 4 materials available simulating a range of mechanical properties, LPE is able to offer our customers a variety of super high resolution parts with a very short turnaround time. For further information visit the DLP Materials page.
Finishing of the DLP parts
With a team of traditional model makers working in house- combined with a full scale spray painting booth, LPE can meet a wide range of finishing requirements including standard finishing (removal of support structures only), painted finishes (matt, satin/spark/tinted/gloss) and metal plating.
Applications of digital light processing
The strengths of digital light processing are its high resolution, material properties and speed of manufacture.
Applications of DLP include:
- Rapid functional prototype parts and fast concept models
- Investment casting patterns for jewellry
- End use durable plastic parts
- Jigs and fixtures
- Rapid tooling – molds and master patterns
- Elastomeric parts – prototypes of grommets, seals, hoses, weatherstripping, tubes, gaskets, spacers and other vibration dampening components
“Stereolithography models allow us to do production intents within days. On one project alone it saved us £100,000 in tooling costs and reduced the lead time from 7 months to 7 days”
