Imagine the ability to create highly detailed, custom-designed items that perfectly capture your brand’s essence. 3D resin printing allows you to do just that and so much more.
This revolutionary technique harnesses the power of liquid resin and UV light to produce stunningly intricate and visually captivating promotional items, taking your branding efforts to new heights.
In this blog, we will delve deeper into the world of 3D resin printing for the promotional products industry. We’ll explore the technology behind it, discuss the equipment and materials required, and guide you through the step-by-step process of creating stunning, customized promotional items.
3D resin printing, also known as stereolithography (SLA), is a form of additive manufacturing that has become increasingly popular in recent years, with various applications in manufacturing, healthcare, and design.
While traditional filament-based 3D printing has been the most common method, 3D resin printing has emerged as an alternative with unique benefits.
The process uses:
Resin is a unique substance that exhibits various characteristics crucial to printing. It typically has a relatively low viscosity, allowing it to flow smoothly and evenly, ensuring precise layer formation during printing.
Moreover, resins are available in various colours, enabling you to produce vibrant and visually appealing promotional products that align with your brand’s identity.
UV light plays a pivotal role in the resin printing process, as it is the key catalyst that triggers the polymerization and solidification of the liquid resin.
When the UV light interacts with the photopolymer resin, it initiates a chemical reaction known as photopolymerization. This process causes the individual resin molecules to link, forming a solid structure layer by layer.
The precise control of UV light exposure is crucial for achieving high-quality prints. During the printing process, each resin layer is exposed to UV light for a specific duration, determined by the resin’s desired thickness and curing properties.
This controlled exposure ensures that the resin cures uniformly and accurately, resulting in a well-defined and structurally sound printed object.
When exposed to specific wavelengths of light, typically in the ultraviolet (UV) spectrum, the photopolymer resin undergoes a process called polymerization.
This process causes the liquid resin to solidify and harden, transforming it into a solid object layer by layer.
The controlled curing of resin ensures the precise formation and stability of each printed layer, resulting in high-resolution and accurately replicated designs.
There are several types of resin printers available in the market, each with its own unique features and capabilities. Some of the most popular types include:
With its ability to produce highly detailed and intricate models, 3D resin printing has found applications in industries ranging from prototyping and jewellery design to healthcare and aerospace.
However, achieving optimal results requires a deep understanding of the entire printing process, from design preparation to post-processing and finishing techniques.
The first step is to prepare your design. Whether you create your own 3D model or obtain one from online repositories, it’s crucial to ensure the model is compatible with resin printing.
Optimize the design by adding supports in areas with overhangs and incorporating drainage holes for resin removal. Use 3D modelling software to adjust settings for resolution, accuracy, layer thickness, and exposure time.
Hollow out the model if necessary, considering wall thickness and creating space for drainage. Once your design is ready, save it in a format compatible with your resin printer.
Now it’s time to set up your resin printer for printing.
Begin by calibrating and levelling the build plate to ensure proper adhesion and consistent layer height. Follow the manufacturer’s instructions for this step, as each printer may have specific requirements
Once the build plate is calibrated, adjust settings such as exposure time, layer height, lift speed, and distance.
Once the printer is set up, you’re ready to start the printing process.
During printing, the build plate gradually lifts, and each layer is exposed to light according to the slicing parameters. The printer repeats this process until the entire object is printed.
After the printing is complete, it’s time for post-processing and finishing to achieve a polished result.
If supports were used, carefully remove them using pliers or cutters, ensuring minimal impact on the print’s surface.
To complete the process, post-curing the print is crucial for optimal strength and stability.
Let’s explore some examples of the diverse range of applications for 3D resin printing:
3D resin printing is widely used for rapid prototyping due to its ability to produce highly detailed and accurate models.
