SLA 3D Printing Services by HLH Prototypes

SLA 3D Printing

Stereolithography or SLA is one of the original 3D printing technologies and one of the most versatile. Our custom SLA Printing Service builds parts layer by layer from a photocurable resin. A high powered UV laser is focused onto the build platform to cure the material one layer at a time.

SLA offers a range of material options and provides parts with great accuracy using CAD and a good surface finish. The parts need to be built with support structures which are removed after the SLA 3D Printing process. SLA is a great option for prototypes and low volume production. Please contact us for more information.

Testimonials

I would like to congratulate you and your company with your service and prototyping quality. The communication with our company was very clear and constructive. The prototypes have a very good quality and the delivery speed are fantastic. With your prototypes we can communicate better and faster with our clients and give them a glance of how the product will look and feel like.Ing. Marc E.J. Van Strydonck Industrial designer

Hi HLH, I received the CNC prototypes last week and have spent the past few days assembling them. I would like to thank you and HLH for the work you have done CNC machining these parts and for delivering them to us as quickly as possible. I look forward to working with HLH again as new projects arise in the future.

Jamie Booth

We have always been very impressed by the level of service and quality provided by HLH. HLH gives our company a real competitive advantage in allowing us to provide our clients with quick and cost effective pre-production quality prototypes.

Danny Kane

The prototypes arrived this morning and they look great. Thank you very much for your work on this project and your prompt and thorough communication. We will certainly be in contact again in the future.

Gareth Lauchlan, BDes ID

We have worked with HLH Prototypes on a number of projects over the past year and have always been very satisfied with their services. We have produce with them high quality rapid prototypes for testing before tooling as a means to make sure we have the best design possible.

We will surely be continuing our working relationship with HLH Prototypes in many years to come

Michael Kitchenham

I would like to convey my sincere thanks to your company for all the work you have provided over the past year in helping to create parts for our models and the dedication you brought to our projects.

Not only was the work done to a high standard, and with considerable speed despite the harsh deadlines, but with the kindest and warmest of attitudes. I am delighted to have worked with your company, and would definitely recommend you to others.

Matthew Shaw

Thank you very much again for your teams speed and effectiveness in producing our RP molds. The quality in finish as always was fantastic especially the clear plastic parts.

Our engineers were just commenting on how the quality in the surface and spray finishing are superior to the models that we had received before from other China based RP houses in the past.

Like the previous years, we look forward to displaying your RP models as various international toy trade shows, where they have proven themselves in the past with strength and durability

HLH Prototypes. What can’t they prototype?

We have had everything from soft rubber to hard plastics, various grades of aluminum to stainless steel parts prototyped via HLH to characterize the performance and gain high level of confidence on design months before actual verification parts and data is available. We have used many of their arsenals of processes from SLA, CNC mill, lathe, forming, wire-cutting, EDM, vacuum cast and my favorite – custom springs. Product development is so much more progressive and easier with HLH as your prototype partner.

Advantages of SLA Printing

Advantages of using our SLA 3D Printing Service

Great for aesthetic models
Good surface finish/parts can be finished
High accuracy and detail/resolution
Wide range of materials including transparent
Fast and inexpensive

SLA is fast, inexpensive and accurate, so is often used for pre-production assembly prototypes, as well as low volume or bespoke production parts such as hearing aids. Due to its good surface finish and ability to create fantastic aesthetic models, SLA is a solution often used for concept presentations and tradeshows – along with other high detail, complex prototypes and products. Stereolithography 3D printed parts are great for communication, sales and marketing models.

What SLA Printing is used for?

SLA is a good choice for prototypes and low volume production where accurate parts with a smooth surface finish are required. There are a range of different materials including high temperature and transparent options. SLA is used for aesthetic models and pre-production assembly prototypes as well as low volume or bespoke production parts requiring high tolerances, or complex geometries.

SLA 3D Printing Tips

SLA produces parts which are highly accurate to CAD and can produce highly complex shapes and geometries. The parts are generally quoted by volume or weight and so in order to keep costs down you can hollow out any thick sections but must remember to leave escape holes for the uncured material.

SLA can deal with thick and thin sections without much trouble but due to the resolution of the printers any walls or other features should be at least 0.4mm wide and high.
