CTB SDK

The CTB SDK offers you the tools and resources you need to add support for the CTB file format to your applications.
  • Enable more slicers to output CTB files
  • Provide the printers using ChiTu Systems with slicing services
  • Push forward standardization of resin 3D printing slice file formats, making it easier for every user to create with 3D printing.

What is an SDK?

SDK, short for Software Development Kit, is a collection of software development tools to create applications for specific purposes.

About CTB file format and the SDK

Before the CTB file format was created, the commonly used slice file types were CBDDLP, CWS, ZIP, SLC, etc. They didn't perform well when dealing with the increasing number of new application scenarios, and their extensibility couldn't satisfy the growing demands of the LCD/DLP resin 3D printer users. So when CHITUBOX Basic V1.6.1 was released (in Nov 2019), CBD-Tech introduced a new file format tailored for LCD/DLP resin 3D printers – CTB (short for CHITUBOX). This format was lightweight, streamlined and highly extensible, and worked better with various resin 3D printers. As the functionalities of CHITUBOX continued to grow, the CTB format got updated continuously to fit in more application scenarios and support more resin printer features.

Later, in 2021, LCD/DLP resin 3D printing technologies kept advancing, and so did the CHITUBOX software. So when CHITUBOX Basic V1.9.0 and CHITUBOX Pro were released, we introduced the new, upgraded CTB. This new format enables you to use the newly-added powerful features of the CHITUBOX software, such as Two-Stage Motion Control (TSMC), Resting Time, Multi-parameter Slice, and more.

As the user base of CTB is rapidly growing, we also see requirements coming out from the developers in our communities and our business partners. To help them offer better products and services to the users, CBD-Tech publishes the standard and officially verified SDK for the CTB format. We hope these tools can simplify creative process for the developers and the partners and help them unleash their creativity.

Frequent Questions

CBD-Tech supports sharing and innovation. We want to help more developers and partners to unleash their creativity, and work with them to provide the users with better products and services.

  1. The CTB SDK enables any organization or individual developer to convert slice files to the CTB format. The converted slice files can be printed on the 3D printers with the Chitu Systems controller boards. The supported printers are listed in Table 1-1 below.

  2. When configuring print settings, the application is able to set independent slice settings for specified layers.
  3. In addition to the print settings of old CTB format, we've added the Resting Time Before Lift, Resting Time After Retract and Resting Time After Lift, allowing you to have a better control over the printer resting times and improve the print effectiveness.
  4. We've also added the TSMC feature to speed up your prints without losing quality.
