3D Printing Overview

What's 3D Printing?

3D printing, also known as additive manufacturing, creates three-dimensional objects by depositing materials layer by layer, based on a digital design. It transforms digital models into tangible items using materials like plastic, resin, or metal.

What Are the Primary Applications of 3D Printing?

3D printing serves numerous purposes across various industries. Key applications include prototyping, custom manufacturing, medical implants, architectural models, jewelry design, and even food production.

What Resolution or Precision Can 3D Printers Achieve?

The resolution of 3D printers, measured in microns, dictates layer height and print detail. Typical consumer printers achieve 50-300 microns, while high-end machines can go below 25 microns, offering exceptional detail and smoothness.

What's the Difference Between 3D Printing and CNC Machining?

3D printing is an additive manufacturing method, building parts by depositing material layer by layer. In contrast, CNC machining is a subtractive method, starting with a solid block of material and removing sections until the desired part is achieved. While 3D printing is often favored for complex geometries and rapid prototyping, CNC machining excels in durability, precision, and material versatility.

3D Printing FAQs

1. What are your tolerances for 3D printing?

3D printing can achieve very high levels of accuracy. Our standard tolerance for 3D printing is ± 0.1mm. But this depends on your part complexity, you can upload your 2D design files and we will evaluate specific tolerances.

2. How long does it take to 3D print parts?

Some important factors, such as your part size, height, complexity and the printing technology used, will affect the printing time. At RapidDirect, we can complete 3D printing projects as fast as 1 day.

3. What’s the maximum size of the 3D prints?

The 3D prints we create will depend on the specification of the 3D printer you choose. We have a wide range of 3D printing machines, allowing us to print different sizes. Large format FDM 3D printers have a build area of up to 36 x 24 x 26 (inches).

On the other hand, you can expect larger SLA printers to print up to 29 x 25 x 21 (inches). SLS unfilled has a 13 inches max dimension, while the glass-filled SLS machine can create prints of 26 x 15 x 23 (inches). The Industrial Polyjet printer has a build area of up to 19 x 15 x 7 (inches).

4. What file format do you accept?

The recommended file formats are STEP (.stp) and STL (.stl) . So if your file is in another format, it is best to convert it to STEP or STL.

5. How much does your 3D printing service cost?

Capital is a huge decider when deciding on the right 3D printing service. Therefore, it is important to know about several factors that can determine the amount of capital you spend printing or outsourcing your project, including chosen 3D printer, the size and design complexity of a model, the material used, and your part volume.
