This path is designed to equip you with any and all resources you need to prototype then test in house! This path will help you 3D print your product with the exact material and process that we use! By the end of this path, you’re already 95% ready for mass production. All that’s left is to send us your part, we’ll give you feedback, and you decide how many you want! 

Path 1

Step #1

Purchase and Set Up Equipment!

1.1 FDM (Optional) - Under 2k$

FDM or filament printers, are many times the very first step. Any FDM printer will be fine. We have a few here that work well but use what you have. These printers offer great quality and and speed. FDM printing is not as messy as resin printing so many times people do general design testing with these machines. FDM prototypes will get you up to 50% the way to mass production but is optional.

1.2 Resin Basic 3K$-10K$ Option

After you get 50% there with FDM you can print your part in resin. Resin prints give much better resolution than FDM and stronger parts but can be a bigger mess. New materials have made this option viable for durable and industrial parts. Follow the manufacturers recommendations when using any printer or equipment. After printing in resin, you have completed 95% of your mass production project.

After any SLA 3D print, the parts will need some post processing done before the parts can be considered complete. The post processing consists of removing any supports, washing off excess resin, and curing the part.


1.3 Resin Pro Package - Under 30K$

If your ready for the more advanced resin printers, Photocentric makes a great work horse for a great price. If you haven’t worked with resin in the past, first get experience with a smaller resin printer. When you perfect your part for mass production on your Magna printer, we can help with the mass production side.  

The LCD Magna printers use a daylight wavelength to print parts. Resin will cure in normal light. Handling resin and parts is a little different than normal 405 UV resin.

The Photocentric Wash and Cure station is our recommended tools to post process prints. Some form of wash and cure is needed to achieve a good quality part.

Washing the parts removes all the excess resin from the prints.

Curing the parts is the final step to post processing.

Step #2

Material Selection and Design Preparation

We have tested these resins. They demonstrate consistent successful results. If you find a different resin in the market you want us to use for a certain purpose, please reach out. We also have many videos on these resins on our instant estimate calculator.

DL110HB-ABS/Nylon like, Black resin that can handle impact, compression but has a higher tensile strength. This is our most common material from Photocentric
Duramax-Creates functional parts that are very durable and long-lasting, with high impact strength. This has a higher toughness than most other resins.
Durable: Creates functional parts that are durable and long-lasting, with high impact strength. Most like Polypropylene with high flex and lower HDT.
DL110HTR Smokey Quartz Translucent: Has nearly identical properties as the DL110HB and DL110HW. DL110HTR has the fastest print time capabilities and a unique Amber appearance.
DL110HW: (White) has essentially identical properties as the black, though it requires more finesse.

Flexible DL220B: A newer resin with the key properties of high elongation, impact absorption, efficient energy damping, strong tear strength, and very low water absorption.

Step #3

Learn the Basics of Resin 3D Printing

Resin SLA (Stereolithography) 3D printing is a type of additive manufacturing technology that uses a liquid photopolymer resin as the printing material. It works by using a UV laser to selectively cure layers of resin, solidifying them into the desired shape. Many SLA printers now use an LCD screen to allow UV light to cure each layer. This process produces highly detailed and precise objects with smooth surface finishes, making it ideal for producing intricate prototypes, jewelry, and other high-resolution parts.

1: Choose the Right Resin: Select resin appropriate for your project, considering factors like color, material properties (e.g., flexibility, durability), and compatibility with your printer.

2:Level the Build Plate: Ensure the build plate is properly leveled to the resin tank to guarantee uniform layer thickness and adhesion.

3: Calibrate Settings: Adjust printer settings such as exposure time, layer height, and lifting speed according to the resin and desired print quality.

4: Use Supports: Utilize support structures in your 3D models to prevent print failures due to overhangs and ensure successful printing of intricate designs.

5: Handle Resin Safely: Wear gloves and eye protection when handling resin, and work in a well-ventilated area to minimize exposure to fumes.

6: Resin Management: Keep resin containers sealed when not in use to prevent contamination and store them away from direct sunlight to avoid premature curing.

7: Post-Processing: After printing, rinse printed objects in isopropyl alcohol (IPA) to remove excess resin, then cure them under UV light to fully solidify the resin.

8: Fine-Tune Supports: Experiment with different support structures and orientations to minimize post-processing and achieve better surface quality.

9: Monitor Prints: Regularly check prints during the process to ensure proper adhesion and address any issues such as layer shifting or failed prints promptly.

10: Learn from Failures: Embrace failures as learning opportunities and analyze the causes to improve your printing skills and optimize future prints.
