What used to take weeks now takes only hours, thanks to stereolithography (SLA). This state-of-the-art process creates three-dimensional models and prototypes from computer designs quickly and flawlessly, catching every detail of your design. This cuts a large swath of time out of the prototyping process and allows you to achieve your finished product faster.
Product designs represent hours of work. You must now ensure that the stereolithography services you choose will produce a product that is worthy of that work, without breaking your budget. When deciding how to bring your design to life, keep the following in mind:
Shop around for competitive SLA rapid prototype pricing
Many companies offer rapid prototyping stereolithography. Therefore, you have the advantage of looking for competitive prices for their services. However, make sure you don't sacrifice quality for a cheap price. Get quotes from several reputable companies and compare both quality and price to make your final decision.
I recommend: Alpha Prototypes requires a low minimum order for SLA prototyping, which can save you money if you have only minimal needs.
Stereolithography.com offers several discounts, as well as price matching.
Ensure your choice of stereolithography services offers rapid turnaround times
One of the best advantages of the stereolithography process is its speed. The ability to turn a CAD file into a three dimensional object in hours makes SLA rapid prototyping possible. So, it's important that the company you choose offer a rapid turnaround time so as to not hold up your manufacturing process.
I recommend: Midwest Prototyping offers various levels of turnaround times, based on the level of finishing desired. You can get high quality with quick turnaround if you are willing to do sanding and painting yourself.
Realize offers finished SLA products within 2 to 4 days of order.
Consider purchasing stereolithography equipment and taking the process in-house
If you have a large enough volume of SLA prototypes to be made, it may be more cost-effective to purchase a stereolithography machine and materials and do your prototyping in-house. Not only will this possibly save money, it also protects the security of your design and ensure you maintain a competitive edge.
I recommend: 3D Systems is the leading manufacturer of SLA machines, offering various models used by many prototyping companies, including the Viper and Viper pro models.
DSM Somos is the leader in stereolithography resins, offering colorless and clear options.
Materialise offers a wide array of stereolithography resins for practically any application, from small detailed pieces to large automotive components.
