3D Systems 3D Lightyear 1.5.2: A Comprehensive Review




If you are looking for a software that can help you prepare STL and SLC files for 3D printing on SLA systems, you might want to check out 3D Systems 3D Lightyear 1.5.2. This software is designed to make your 3D printing workflow easier, faster, and more reliable. In this article, we will review what 3D Lightyear is, what are its features and benefits, and how to get started with it.




3D Systems 3D Lightyear 1.5.2



What is 3D Lightyear?




3D Lightyear is a file preparation software that is used on Windows-based CAD/CAM or other workstations to prepare STL and SLC files for part building on SLA systems. SLA stands for stereolithography, which is a type of additive manufacturing that uses a laser to cure liquid resin into solid parts. STL and SLC are file formats that contain information about the geometry of the parts. STL stands for stereolithography file format, which is composed of triangles that define the surface of the part. SLC stands for slice file format, which is composed of slices that define the cross-sections of the part. Both file formats are widely used in the 3D printing industry.


3D Lightyear was developed by 3D Systems, which is a leading company in the field of additive manufacturing. The company was founded in 1986 by Chuck Hull, who invented SLA technology. Since then, the company has been providing solutions for various industries, such as aerospace, automotive, healthcare, dental, education, entertainment, jewelry, and more. The company offers a range of products and services, such as printers, materials, software, scanners, haptic devices, cloud services, on demand manufacturing, digital design tools, consulting, training, support, etc.


3D Lightyear was first released in 1999 as a replacement for Maestro software, which was the previous file preparation software for SLA systems. The software has been updated several times since then, with the latest version being 3D Lightyear 1.5.2, which was released in 2010. The software is compatible with Windows XP, Vista, and 7 operating systems. The software is also compatible with various SLA systems, such as SLA-250, SLA-3500, SLA-5000, SLA-7000, Viper Pro, Viper si2, iPro 8000, and iPro 9000. The software can also be used with other 3D Systems products, such as Accura materials, 3D Sprint software, and 3D Connect service. What are the features of 3D Lightyear?




3D Lightyear has many features that can help you prepare STL and SLC files for 3D printing on SLA systems. Here are some of the main features of the software:


STL and SLC file preparation




One of the core functions of 3D Lightyear is to import, edit, and optimize STL and SLC files for 3D printing. You can import STL and SLC files from various CAD/CAM software or other sources into 3D Lightyear. You can also create SLC files from STL files using the Slice function. Once you have imported the files, you can edit them using various tools and functions, such as:


  • Scale: You can scale the parts to fit the build platform or to adjust the size of the parts.



  • Translate: You can move the parts to different positions on the build platform or in the 3D space.



  • Rotate: You can rotate the parts around different axes or by a specific angle.



  • Mirror: You can mirror the parts along different planes or axes.



  • Boolean: You can perform boolean operations on the parts, such as union, intersection, or difference.



  • Repair: You can repair the parts by fixing errors or defects in the STL or SLC files, such as holes, gaps, overlaps, inverted normals, etc.



  • Optimize: You can optimize the parts by reducing the number of triangles or slices in the STL or SLC files, which can improve the quality and speed of the 3D printing process.



You can also view and analyze the parts using various tools and functions, such as:


  • Zoom: You can zoom in or out of the parts to see more details or to get a better overview.



  • Pan: You can pan the parts to move them across the screen.



  • Orbit: You can orbit the parts to view them from different angles or perspectives.



  • Select: You can select one or more parts to perform actions on them or to see their properties.



  • Measure: You can measure the dimensions, volume, surface area, mass, center of gravity, etc. of the parts.



  • Analyze: You can analyze the quality and accuracy of the parts by checking for errors, defects, deviations, etc.



Part setup and orientation




Another important function of 3D Lightyear is to arrange, align, and orient the parts on the build platform. This can affect the quality and efficiency of the 3D printing process. You can use various tools and functions to set up and orient your parts, such as:


  • Auto Arrange: You can automatically arrange your parts on the build platform to maximize the use of space and minimize supports.



  • Auto Align: You can automatically align your parts on the build platform to match their orientation with respect to gravity or other factors.



  • Auto Orient: You can automatically orient your parts on the build platform to optimize their quality and accuracy by minimizing distortion or curling.



  • Manual Arrange: You can manually arrange your parts on the build platform by dragging and dropping them to different positions.



  • Manual Align: You can manually align your parts on the build platform by using snap points or reference planes.



  • Manual Orient: You can manually orient your parts on the build platform by using rotation handles or input boxes.



Support generation and editingSupport generation and editing




Another essential function of 3D Lightyear is to create, modify, and delete supports for the parts. Supports are structures that are added to the parts to prevent them from collapsing, warping, or detaching during the 3D printing process. Supports are usually removed after the 3D printing process is completed. You can use various tools and functions to generate and edit supports, such as:


  • Auto Support: You can automatically generate supports for your parts based on predefined parameters, such as support type, density, angle, size, etc.



  • Manual Support: You can manually generate supports for your parts by using drawing tools or selecting points on the parts.



  • Edit Support: You can edit the supports for your parts by changing their properties, such as position, orientation, shape, size, etc.



  • Delete Support: You can delete the supports for your parts by selecting them and pressing the delete key or using the delete function.



Build file creation and export




The final function of 3D Lightyear is to generate and save build files for SLA systems. Build files are files that contain all the information and instructions for the SLA system to print the parts. Build files are usually in the format of .bld or .slc. You can use various tools and functions to create and export build files, such as:


  • Build Settings: You can adjust the build settings for your parts, such as layer thickness, hatch spacing, exposure time, laser power, etc.



  • Build Preview: You can preview the build process for your parts by using a simulation tool that shows how the parts will be printed layer by layer.



  • Build File: You can generate the build file for your parts by using the build function that creates a .bld or .slc file that can be transferred to the SLA system.



  • Export File: You can export the build file for your parts by using the export function that saves the .bld or .slc file to a specific location or device.
