But skipping the prototyping phase can be a costly mistake. Prototypes are more than mockups &#8211; they\u2019re essential tools for validation, testing, feedback, and even investor confidence. At X-PRO CAD, we believe that prototyping is not just a step &#8211; it\u2019s the step that sets the tone for everything that follows.<\/p>\n&nbsp;\n\n<!-- divi:paragraph {\"fontSize\":\"medium\"} -->\n<p class=\"has-medium-font-size\"><strong>What Is Prototyping?<\/strong><\/p>\n<!-- divi:paragraph {\"fontSize\":\"medium\"} -->\n<p class=\"has-medium-font-size\">Prototyping is the process of creating an early version of your product to evaluate its design, function, and usability. Prototypes can be physical (like a 3D-printed object) or digital (such as a simulation or CAD animation). Depending on the stage you\u2019re in, a prototype might be a basic model to test size and ergonomics, a semi-functional version for user testing, or a near-final version used to finalize design and prepare for manufacturing.<\/p>\n&nbsp;\n\n<!-- divi:paragraph {\"fontSize\":\"medium\"} -->\n<p class=\"has-medium-font-size\"><strong> Why It Matters<\/strong><\/p>\n<!-- divi:paragraph {\"fontSize\":\"medium\"} -->\n<p class=\"has-medium-font-size\">Prototyping helps you catch design flaws early before investing in tooling or production. It allows you to get real feedback from users or testers, improve usability, durability, and functionality, pitch to investors with something tangible, and speed up the overall development cycle. Skipping prototyping often results in unexpected failures in later stages, costly rework and redesign, delays in production timelines, and disappointed customers or backers.<\/p>\n&nbsp;\n\n<!-- divi:paragraph {\"fontSize\":\"medium\"} -->\n<p class=\"has-medium-font-size\"><strong>How X-PRO CAD Handles Prototyping<\/strong><\/p>\n<!-- divi:paragraph {\"fontSize\":\"medium\"} -->\n<p class=\"has-medium-font-size\">We take a collaborative, iterative approach. Once your CAD model is ready, we offer rapid prototyping services using various methods like 3D printing, CNC machining, and silicone molding. We\u2019ll help you choose the right material, method, and fidelity level based on your goals and budget. We also offer design revisions based on prototype testing results\u2014so you\u2019re not just getting a model, you\u2019re getting a learning tool that drives real improvements.<\/p>\n&nbsp;\n\n<!-- divi:paragraph {\"fontSize\":\"medium\"} -->\n<p class=\"has-medium-font-size\"><strong>Prototype Types We Offer<\/strong><\/p>\n<!-- divi:paragraph {\"fontSize\":\"medium\"} -->\n<p class=\"has-medium-font-size\">We offer conceptual prototypes &#8211; quick, low-cost models to evaluate size and aesthetics; functional prototypes &#8211; built to test mechanical parts, movement, or usability; and presentation prototypes &#8211; polished and detailed for investor meetings or marketing use.<\/p>\n&nbsp;\n\n<!-- divi:paragraph {\"fontSize\":\"medium\"} -->\n<p class=\"has-medium-font-size\">One client came to us with a medical device idea. We prototyped three iterations within two weeks, leading to crucial changes in button placement and grip. Their next investor pitch closed in a single meeting &#8211; thanks to a polished, test-proven prototype in hand.\n<\/p>\n&nbsp;\n\n<!-- divi:paragraph {\"fontSize\":\"medium\"} -->\n<p class=\"has-medium-font-size\">Prototyping is not optional &#8211; it\u2019s the difference between a risky guess and a smart, confident launch. At X-PRO CAD, we help you prototype quickly and effectively so you can move forward with clarity and momentum. Build smarter. Launch stronger. Let\u2019s bring your vision to life &#8211; one prototype at a time.\n\n\n<\/p>\n&nbsp;[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]\n","protected":false},"excerpt":{"rendered":"<p>In product development, there\u2019s a tempting urge to move fast\u2014especially if you&#8217;re excited about your idea or under pressure to launch.

In this blog post, we will explain the differences between STL, STP, OBJ and IGS files, and tell you which format is best for your <a href=\"https:\/\/www.x-procad.com\/manufacturing\/\">manufacturing process.<\/a><\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:image {\"id\":4784} -->\n<figure class=\"wp-block-image\"><img src=\"https:\/\/hlhrapid.com\/wp-content\/uploads\/2022\/10\/3d-model-file-format.jpg\" alt=\"3d model file formats for manufacturing\" class=\"wp-image-4784\"\/><\/figure>\n<!-- \/wp:image -->\n\n<!-- wp:heading -->\n<h2 class=\"wp-block-heading\">STL, STP, OBJ and IGS file formats explained<\/h2>\n<!-- \/wp:heading -->\n\n<!-- wp:paragraph {\"fontSize\":\"medium\"} -->\n<p class=\"has-medium-font-size\"><strong>STL <\/strong>\u2014\u00a0The most common format for 3D printing. STL is a 3D file format whereby the model is composed of triangular mesh geometry. It is a simple format that is storage-efficient and can be easily imported into a slicing software and\u00a0printed quickly.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph {\"fontSize\":\"medium\"} -->\n<p class=\"has-medium-font-size\"><strong>STP<\/strong>&nbsp;\u2014 STP (.step) files are better suited for curved designs or when you need an extremely accurate model. Though STEP is more complex, it contains more information than STL files and is easier to edit and repair after being exported. STEP is also often considered the best file format for sharing 3D models as it is a&nbsp;neutral file type. It is worth noting that the higher the model accuracy, the larger the file.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph {\"fontSize\":\"medium\"} -->\n<p class=\"has-medium-font-size\"><strong>OBJ&nbsp;<\/strong>\u2014&nbsp;A file format similar to STL. A key difference is that OBJ files can store colour, texture and material information and not just solely geometrical data. It is, however, worth noting that colour and texture data are stored in a separate file, which can add to complexity.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph {\"fontSize\":\"medium\"} -->\n<p class=\"has-medium-font-size\"><strong>IGS<\/strong>&nbsp;\u2014 A file format similar to STP. Both IGS (.iges)&nbsp;and STP files contain more detailed information than STL and OBJ files; however, IGES files are generally larger in size. So if you need to send CAD designs via email, using an STP format can often help reduce the attachment size.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:heading -->\n<h2 class=\"wp-block-heading\">Which format is needed for manufacturing?<\/h2>\n<!-- \/wp:heading -->\n\n<!-- wp:paragraph {\"fontSize\":\"medium\"} -->\n<p class=\"has-medium-font-size\"><strong>STL\/OBJ: 3D Printing<\/strong><\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph {\"fontSize\":\"medium\"} -->\n<p class=\"has-medium-font-size\">STL and OBJ files contain all the information necessary to 3D print a model.&nbsp;Although, IGS files can be edited and repaired, they are more difficult to work with than STL or OBJ files. Hence,&nbsp;are not typically used for 3D printing. Bear in mind that&nbsp;a poor-quality export will result in a poor print.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph {\"fontSize\":\"medium\"} -->\n<p class=\"has-medium-font-size\"><strong>STP\/IGS: CNC Machining, Injection Moulding,&nbsp;Sheet Metal<\/strong><\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph {\"fontSize\":\"medium\"} -->\n<p class=\"has-medium-font-size\">STP and IGS files are typically used for <a href=\"https:\/\/www.x-procad.com\/cnc-machining\/\">CNC machining<\/a>, <a href=\"https:\/\/www.x-procad.com\/injection-molding\/\">injection molding<\/a> and sheet metal fabrication processes. These file formats contain more detailed information than STL files, and they can be used to create models with multiple colours and complex geometries.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph {\"fontSize\":\"medium\"} -->\n<p class=\"has-medium-font-size\"><strong>STL\/OBJ\/STP\/IGS: Vacuum Casting<\/strong><\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:paragraph {\"fontSize\":\"medium\"} -->\n<p class=\"has-medium-font-size\">The vacuum (urethane) <a href=\"https:\/\/www.x-procad.com\/casting\/\">casting process<\/a> is unique in that it requires a master model made via SLA 3D printing or CNC \u2014 depending on a case-by-case basis. If the master is made with 3d printing, a .stl or .obj file is needed. If it is made with CNC, a .stp or .igs file is needed.<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:heading -->\n<h2 class=\"wp-block-heading\">Manufacturing with X-PRO<\/h2>\n<!-- \/wp:heading -->\n\n<!-- wp:paragraph {\"fontSize\":\"medium\"} -->\n<p class=\"has-medium-font-size\">If you are not sure which 3D file format is needed, <strong>the safest options<\/strong> are STL for 3D printing and STP for all other manufacturing processes.
