3D Printing

has quickly shown itself to be future of manufacturing and is opening up a world of 3D prototyping and low-volume rapid manufacturing possibilities.

We at HLH have been providing online 3D printing prototyping solutions for over 10 years. Rapid prototyping via SLA and SLS, paired with our extensive experience – enables us to deliver high precision, high-quality parts & prototypes to customers all over the world.

What’s The Difference between SLA and SLS 3D Printing ?

SLA 3D Printing

is a liquid resin which is printed in 3D, then cured to solidify – and is our most popular option. A precise laser cures the liquid resin in the build chamber, which builds accurate parts one layer at a time. Please see here for more info.

SLS 3D printing

process uses powdered components. which are selectively fused into during the printing process. Here a precision laser fuses powder material together one layer at a time, to build accurate and strong nylon parts. SLS Printing is ideal for functional, more durable, high-stress parts & components. For more info please click here.

SLA: 0.4mm
SLS: 1mm

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.

3D Printing Tips

For 3D printing prototypes, there are many simple design rules to follow which can improve the results of the parts you print. Minimum feature size is one example. Logos and other fine detailed features need to be designed a minimum size to print.

For SLA: 0.4mm wide and high
For SLS: 1mm wide and high

Whether you are looking for concept models (appearance models), rapid prototyping for functional parts, or direct digital manufacturing for series production end-use parts, it is important to look for flexibility when searching for prototyping companies.

At HLH, we are highly aggressive on 3D print pricing, so much so that we can often deliver parts faster and cheaper than local suppliers in your home country, even with shipping costs and distances taken into account. Plus, we can take your part to the next level with our advanced surface finishing options that can turn a good part into a great part that will help you sell.
