Printing Parts Case

Why choose Printing

High Precision: SLA 3D printing offers excellent dimensional accuracy and high-resolution printing, making it suitable for applications requiring complex details and fine features.

Smooth surface finish: SLA prints typically have a smooth and polished surface finish, reducing the need for extensive post-processing and providing a visually appealing end product.

Broad material compatibility: SLA printers can use a variety of resin materials, including those with specific properties such as transparency, flexibility or high temperature resistance, allowing for a wide range of applications.

Support structures: SLA printers can generate support structures that can be easily removed after printing, enabling the production of complex geometry and overhang structures without compromising the quality of the final print.

Fast printing speed: SLA 3D printers can produce prints relatively quickly compared to other 3D printing technologies because they are able to cure the entire layer at once.

FAQs

What are your tolerances for 3D printing?

Standard tolerance is ±0.2mm （with scaling for large parts）, and an upgraded process offers ±0.05mm precision for select technologies.

3D printing can achieve remarkably high levels of accuracy, ensuring that your parts meet stringent specifications. At Trendy , our standard tolerance for 3D printing is ±0.1mm. However, the exact tolerance can vary depending on the complexity and design of your part. For highly detailed or intricate components, tolerances might need to be adjusted to ensure optimal results. To provide you with the most accurate assessment, you can upload your 2D design files through our platform. Our expert team will evaluate your design and determine the specific tolerances required to achieve the best possible outcome for your project.

How long does it take to 3D print parts?

The time required to 3D print parts depends on several key factors, including part size, height, complexity, and the chosen printing technology. Larger or more complex parts naturally take longer to print than smaller, simpler ones. At Trendy we understand the importance of fast turnaround times. Leveraging advanced 3D printing technologies and efficient processes, we can complete many 3D printing projects in as little as one day. For precise time estimates tailored to your specific project, you can upload your design files, and our team will provide a detailed timeline based on your unique requirements.

What file format do you accept?

At Trendy we accept a variety of file formats to ensure compatibility with our 3D printing systems. The recommended file formats are STEP (.stp) and STL (.stl), as they provide the best accuracy and detail. If your design file is in a different format, we advise converting it to either STEP or STL to ensure optimal results. These formats preserve the geometric data and intricate details necessary for precise and high-quality prints. Should you need assistance with file conversion or have questions about specific formats, our support team is always ready to help.

How much does your 3D printing service cost?

The cost of our 3D printing service depends on several factors. These include the type of 3D printer chosen, the size and design complexity of the model, the material used, and the volume of parts required. Larger and more intricate designs typically require more resources and time, influencing the overall cost. Material choice also plays a significant role; different materials vary in price based on their properties and suitability for specific applications. At RapidDirect, we provide detailed quotes tailored to your project’s specifications. Understanding these variables helps you manage capital effectively while achieving high-quality results.

How can I choose a 3D printing technology?

Choosing the right 3D printing technology depends on your project’s specific requirements. Consider factors such as the desired material, part complexity, surface finish, strength, and budget. For high-detail and smooth finishes, SLA is ideal. For strong, functional parts, SLS or HP MJF might be better suited. FDM is great for large, durable parts at a lower cost, while SLM is perfect for high-strength metal components. Consulting with our 3D printing experts can help you make an informed decision. Provide your design specifications, and we’ll recommend the best technology to meet your needs efficiently and cost-effectively.
