In 3D printing technology, these terms are distinct and should never be used interchangeably. Tolerances define how precise the designer needs to be. In other words, it is the amount of wiggle room allowed in a design or manufacturing, which depends on individual or industry standards.&nbsp;<\/p>\n\n\n\n<p>When you mention accuracy, it simply refers to how consistent your dimensions are compared to the actual value. In this case, the true value is the dimensions of the digitized 3D printing model. On the other hand, accuracy defines how close the dimensions of 3D-printed parts are to those of the model.&nbsp;<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"tolerances-in-3d-printing-what-to-expect\"><strong>Tolerances in 3D Printing: What to Expect<\/strong><\/h2>\n\n\n<p>Different 3D printing technologies offer varying capabilities when it comes to tolerances. The achievable accuracy depends on the part size, chosen material, and geometry\u2014especially if the design is bulky, as this can lead to more shrinkage.<\/p>\n\n\n    <section class=\"article-author-block\">\r\n        <div class=\"article-content-wrapper\">\r\n            <div class=\"author-block\">\r\n                                        <div class=\"author-info\">\r\n                            <h4 class=\"author-name\">Nikolaus Mroncz<\/h4>\r\n                            <p class=\"author-position\">Head of Sales Engineering<\/p>\r\n                        <\/div>\r\n                                    <\/div>\r\n                <div class=\"quote-block\" style=\"border-color: #0E6AED;\">\r\n                    <p>Though post-processing can help improve dimensional accuracy, tight tolerances aren\u2019t always guaranteed on the first try.

\n\n<h2 class=\"wp-block-heading\" id=\"h-mjf-3d-printing-tolerances\"><strong>MJF 3D Printing Tolerances<\/strong><\/h2>\n\n\n<p>HP Multi Jet Fusion (MJF) is one of the most cost-effective 3D printing technologies offering fine tolerances. It works by applying a fusing agent to powdered material, followed by a heat source that systematically cures each layer. Heated build chambers raise the overall powder temperature, minimizing warping and shrinkage while allowing gradual temperature changes that enhance dimensional accuracy.<\/p>\n\n\n\n<p>However, heat buildup\u2014especially from the infrared lamps used during printing\u2014can still lead to thermal stresses. Thicker geometries, broad surfaces, and uneven wall thicknesses are more prone to warping or twisting due to shrinkage. To reduce these risks, it&#8217;s best to follow design guidelines similar to those used for injection-moulded parts.<\/p>\n\n\n<div class=\"custom-table-block \" id=\"table-id-824\" >\r\n\t<div class=\"search-input-wrapper\">\r\n\t\t<svg width=\"16\" height=\"16\" viewBox=\"0 0 16 16\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\r\n\t\t\t<path d=\"M15.7812 13.833L12.6659 10.7177C12.5252 10.5771 12.3346 10.499 12.1347 10.499H11.6253C12.4877 9.39596 13.0002 8.00859 13.0002 6.49937C13.0002 2.90909 10.0911 0 6.50083 0C2.91056 0 0.00146484 2.90909 0.00146484 6.49937C0.00146484 10.0896 2.91056 12.9987 6.50083 12.9987C8.01006 12.9987 9.39742 12.4863 10.5004 11.6239V12.1332C10.5004 12.3332 10.5786 12.5238 10.7192 12.6644L13.8345 15.7797C14.1282 16.0734 14.6032 16.0734 14.8938 15.7797L15.778 14.8954C16.0718 14.6017 16.0718 14.1267 15.7812 13.833ZM6.50083 10.499C4.29167 10.499 2.50122 8.71165 2.50122 6.49937C2.50122 4.29021 4.28855 2.49976 6.50083 2.49976C8.70999 2.49976 10.5004 4.28708 10.5004 6.49937C10.5004 8.70852 8.71311 10.499 6.50083 10.499Z\" fill=\"#476175\"\/>\r\n\t\t<\/svg>\r\n\t\t<input type=\"search\" class=\"table-search-input\" id=\"table-search-824\" placeholder=\"Table search\">\r\n\t<\/div>\t\r\n\t<div class=\"table-wrapper\">\r\n\t\t<table style=\"border-collapse: collapse; width: 100%;\">\n<tbody>\n<tr>\n<td style=\"width: 20.7474%;\"><b>Parameter<\/b><\/td>\n<td style=\"width: 79.1237%;\"><b>Value<\/b><\/td>\n<\/tr>\n<tr>\n<td style=\"width: 20.7474%;\"><span style=\"font-weight: 400;\">Tolerance<\/span><\/td>\n<td style=\"width: 79.1237%;\"><span style=\"font-weight: 400;\">\u00b1 0.3% (lower limit: \u00b1 0.3 mm)<br \/>\n<\/span><b>Pro tip:<\/b><span style=\"font-weight: 400;\"> For tighter tolerances, PA 12 glass-filled is recommended.\u00a0<\/span><\/td>\n<\/tr>\n<tr>\n<td style=\"width: 20.7474%;\"><span style=\"font-weight: 400;\">Shrinkage\/Warping<\/span><\/td>\n<td style=\"width: 79.1237%;\"><span style=\"font-weight: 400;\">Shrinkage usually occurs in the 2 &#8211; 3% range.

parts by extruding thermoplastic material onto a build plate, layer by layer. It is well-suited for larger parts, mechanical geometries, and applications that don\u2019t require ultra-fine details. FDM is widely used across industries due to its versatility and affordability.<\/p>\n\n\n\n<p>Like SLA, FDM requires support structures, and post-processing can introduce dimensional inaccuracies, especially in heavily supported areas. Additionally, narrow features may not be accurately resolved because of the nozzle width. Shrinkage begins immediately as the material cools after deposition, and tolerances can vary significantly between desktop and industrial FDM printers.<\/p>\n\n\n<div class=\"custom-table-block \"

Removal of the supports not only affects the surface finish but also sometimes leads to material removal at that point. This creates inaccuracy in the dimensions.<\/p>\n\n\n\n<p>Finishing processes like sanding can be used to cut out extra dimensions whereas techniques like coating and painting can add little to the dimensions. In DMLS, sometimes 1\u20132 mm of additional material is applied to significant surfaces and is machined accordingly after printing. This is a way to correct the dimensions and achieve tight tolerances.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"factors-affecting-tolerances-in-3d-printing-technology\"><strong>Factors Affecting Tolerances in 3D Printing Technology<\/strong><\/h2>\n\n\n<p>In 3D printing, the major factors influencing the tolerances are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Material shrinkage (change in volume from a change in state from liquid to solid)<\/li>\n\n\n\n<li>Layer thickness<\/li>\n\n\n\n<li>Minimum feature size<\/li>\n\n\n\n<li>Build size (maximum size of the part to be printed, depending on the technology)<\/li>\n<\/ul>\n\n\n<h3 class=\"wp-block-heading\" id=\"h-1-material-shrinkage\"><strong>1. Material Shrinkage<\/strong><\/h3>\n\n\n<p>The build material used in the 3D printing processes includes thermoplastics filaments, powders, resins, liquid photopolymers and metal powder. All these materials have a varying degree of shrinkage. As a principle of 3D printing, the polymers naturally shrink when they are cooled and solidified during the printing process. The rate of shrinkage is specific to a definite material.<\/p>\n\n\n<div class=\"custom-table-block table-with-white-space\" id=\"table-id-41\" >\r\n\t<div class=\"search-input-wrapper\">\r\n\t\t<svg width=\"16\" height=\"16\" viewBox=\"0 0 16 16\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\r\n\t\t\t<path d=\"M15.7812 13.833L12.6659 10.7177C12.5252 10.5771 12.3346 10.499 12.1347 10.499H11.6253C12.4877 9.39596 13.0002 8.00859 13.0002 6.49937C13.0002 2.90909 10.0911 0 6.50083 0C2.91056 0 0.00146484 2.90909 0.00146484 6.49937C0.00146484 10.0896 2.91056 12.9987 6.50083 12.9987C8.01006 12.9987 9.39742 12.4863 10.5004 11.6239V12.1332C10.5004 12.3332 10.5786 12.5238 10.7192 12.6644L13.8345 15.7797C14.1282 16.0734 14.6032 16.0734 14.8938 15.7797L15.778 14.8954C16.0718 14.6017 16.0718 14.1267 15.7812 13.833ZM6.50083 10.499C4.29167 10.499 2.50122 8.71165 2.50122 6.49937C2.50122 4.29021 4.28855 2.49976 6.50083 2.49976C8.70999 2.49976 10.5004 4.28708 10.5004 6.49937C10.5004 8.70852 8.71311 10.499 6.50083 10.499Z\" fill=\"#476175\"\/>\r\n\t\t<\/svg>\r\n\t\t<input type=\"search\" class=\"table-search-input\" id=\"table-search-41\" placeholder=\"Table search\">\r\n\t<\/div>\t\r\n\t<div class=\"table-wrapper\">\r\n\t\t<table style=\"border-collapse: collapse; width: 100%;\">\n<tbody>\n<tr>\n<td style=\"width: 11.2113%;\"><b>Factor<\/b><\/td>\n<td style=\"width: 36.8557%;\"><b>Impact on Shrinkage and Tolerance<\/b><\/td>\n<td style=\"width: 51.8041%;\"><b>Practical Solutions<\/b><\/td>\n<\/tr>\n<tr>\n<td style=\"width: 11.2113%;\"><span style=\"font-weight: 400;\">Material Type<\/span><\/td>\n<td style=\"width: 36.8557%;\"><span style=\"font-weight: 400;\">Different materials shrink at different rates.

This not only affects the surface finish but can slightly alter the intended dimensions\u2014especially on features like spheres or chamfers. Reducing the layer height can minimize this effect, and post-processing methods such as sanding, polishing, or vapor smoothing are often used to restore the intended precision.<\/p>\n                <\/div>\r\n        <\/div>\r\n    <\/section>\r\n\n\n<h3 class=\"wp-block-heading\" id=\"h-3-minimum-feature-size\"><strong>3. Minimum Feature Size<\/strong><\/h3>\n\n\n<p>Minimum feature size refers to the smallest detail a 3D printer can reliably produce. It depends on both the printing technology and machine-specific parameters such as nozzle diameter, layer thickness, and laser beam size.<\/p>\n\n\n\n<p>For FDM, the feature size depends on nozzle and layer height:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>X-Y Resolution<\/strong>: Determined by the nozzle diameter. A smaller nozzle allows finer details on horizontal surfaces.<\/li>\n\n\n\n<li><strong>Z Resolution<\/strong>: Controlled by layer thickness. Thinner layers allow better resolution on vertical and sloped surfaces.<\/li>\n\n\n\n<li>For example, a 0.4 mm nozzle typically prints features no smaller than 0.4\u20130.5 mm in X-Y. Smaller text or grooves are better printed with a 0.2 mm nozzle.<\/li>\n\n\n\n<li><strong>Note<\/strong>: Feature detail varies based on part orientation. Details on the top surface will be sharper than those on vertical sides.<\/li>\n<\/ul>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:66.66%\">\n<p>Powder-based and resin technologies rely on laser beam or light source diameter and material characteristics for resolution:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Laser\/light spot size<\/strong>: Defines the smallest X-Y feature printable.<\/li>\n\n\n\n<li><strong>Layer height<\/strong>: Affects Z-resolution, just like in FDM.<\/li>\n\n\n\n<li><strong>Material reuse<\/strong>: In powder-based methods (MJF, SLS, DMLS), reused powder becomes less spherical over time, reducing resolution consistency and dimensional reliability.<\/li>\n<\/ul>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\">\n<figure class=\"wp-block-image size-large is-resized\"><div class=\"wp-block-image__wrap\"><img decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/12\/minimum-feature-size-icon-1024x1024.png\" alt=\"Minimum feature size icon\" class=\"wp-image-104032\" style=\"max-width:229px;height:auto\" srcset=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/12\/minimum-feature-size-icon-1024x1024.png 1024w, https:\/\/xometry.pro\/wp-content\/uploads\/2023\/12\/minimum-feature-size-icon-300x300.png 300w, https:\/\/xometry.pro\/wp-content\/uploads\/2023\/12\/minimum-feature-size-icon-150x150.png 150w, https:\/\/xometry.pro\/wp-content\/uploads\/2023\/12\/minimum-feature-size-icon-768x768.png 768w, https:\/\/xometry.pro\/wp-content\/uploads\/2023\/12\/minimum-feature-size-icon-1536x1536.png 1536w, https:\/\/xometry.pro\/wp-content\/uploads\/2023\/12\/minimum-feature-size-icon-2048x2048.png 2048w, https:\/\/xometry.pro\/wp-content\/uploads\/2023\/12\/minimum-feature-size-icon-84x84.png 84w, https:\/\/xometry.pro\/wp-content\/uploads\/2023\/12\/minimum-feature-size-icon-102x102.png 102w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><a class=\"wp-block-image__fancy-box-button\" href=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/12\/minimum-feature-size-icon.png\" data-fancybox=\"gallery-11381\" data-caption=\"\" aria-label=\"Open full image\"><img src=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/12\/minimum-feature-size-icon.png\" class=\"wp-block-image__fancy-box-button-thumbnail wp-post-image\" alt=\"\" loading=\"lazy\" decoding=\"async\"><svg class=\"wp-block-image__fancy-box-button-icon\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"18\" height=\"18\" viewBox=\"0 0 18 18\" fill=\"none\" aria-hidden=\"true\">\r\n               <path d=\"M0 2V6H2V2H6V0H2C0.895 0 0 0.895 0 2ZM2 12H0V16C0 17.105 0.895 18 2 18H6V16H2V12ZM16 16H12V18H16C17.105 18 18 17.105 18 16V12H16V16ZM16 0H12V2H16V6H18V2C18 0.895 17.105 0 16 0Z\" fill=\"#092C47\"\/>\r\n             <\/svg><\/a><\/div><\/figure>\n<\/div>\n<\/div>\n\n\n<h3 class=\"wp-block-heading\" id=\"h-4-build-size\"><strong>4. Build Size<\/strong><\/h3>\n\n\n<p>Build size refers to the maximum overall size of the part that can be manufactured by a printer or the maximum size that is fitted onto a build area in a printer. The bigger the part, the more time required for it to cure or cool down. During this process, a lot of shrinkage and warpage takes place due to uneven cooling.<\/p>\n\n\n\n<p>Big parts also require a lot of support structures (depends on design and process though). When removed, it also affects the surface quality.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"h-sourcing-3d-prints-with-tighter-tolerances\"><strong>Sourcing 3D Prints With Tighter Tolerances<\/strong><\/h2>\n\n\n<p>Achieving tight tolerances in 3D printing is not just about selecting the right technology\u2014it&#8217;s about understanding the interaction between material behavior, printer capability, part geometry, and process settings. Designers should account for tolerance requirements early in the CAD stage, applying process-specific design rules and planning for post-processing where needed. When precision is critical, choosing stable materials, and reliable technologies like SLA, PolyJet, or DMLS can make a significant difference.<\/p>\n\n\n\n<p>Alternatively, working with an experienced manufacturing partner gives access to industrial-grade machines, controlled environments, and expert feedback\u2014ensuring your parts meet both functional and dimensional specifications.
