3D Printing Materials
3D printing offers unmatched flexibility and speed for product development. Whether you need functional prototypes or small-batch production, our advanced 3D printers can quickly turn your designs into reality.
We work with a variety of materials such as ABS, PLA, Nylon, Resin, and PETG, delivering parts with excellent detail, accuracy, and surface quality. Compared to traditional manufacturing, 3D printing reduces tooling costs, shortens lead times, and allows rapid design iteration — helping you move seamlessly from concept to final product.
With You Through Every Process Step
Step 1: Upload your 3D design file
Step 2: Choose materials & process (FDM, SLA, SLS)
Step 3: We print & inspect your parts
Does the Standard Inspection include a dimensional report?
No. A standard inspection is a simple dimensional check and no documentation will ship with your parts.
Can you verify GD&T geometric tolerances like position, flatness, surface profile, parallelism, etc..?
Upgrade to Formal Inspection with Dimensional Report, CMM Inspection with Dimensional Report, or First Article Inspection to receive a full dimensional inspection report that is correlated to your drawing.
Step 4: Package Delivered worldwide within days
In the packaging phase, we ensure that all products are securely packaged to protect them during transit and storage. Each item is carefully wrapped using appropriate protective materials such as bubble wrap, foam inserts, and corrugated boxes. Our packaging process is designed to prevent damage, preserve product integrity, and ensure that all items reach their destination in perfect condition. Clear labeling and detailed documentation are also included to facilitate easy identification and handling. Our commitment to quality extends to every aspect of the process, including packaging, ensuring complete customer satisfaction.
A Quick Guide to Designing 3D Printed Parts
Optimize your design for faster, stronger, and more cost-effective 3D printing results. Reduce material waste, improve accuracy, and ensure your prototype is production-ready.
Choose the Right Material for Functionality
Different materials like ABS, PLA, or Nylon have unique strengths. Select the right one based on flexibility, heat resistance, or surface finish needs.
Optimize Wall Thickness
Keep walls between 1.0–2.5 mm to balance strength and print speed. Thin walls may warp; thick ones waste material.
Avoid Sharp Edges
Smooth transitions reduce stress points and improve overall strength. Rounded corners print better and look more professional.
Add Support-Friendly Designs
If your model has overhangs or complex shapes, include angles or split parts to minimize support structures and reduce post-processing.
Ensure Proper Tolerances
3D printing precision varies by material and printer type — usually ±0.1–0.2 mm. For high-precision parts, use engineering drawings for guidance.
