Printed parts shift from red to beige at around 30\u00b0C, giving this material a strong visual effect that makes temperature changes easy to notice with the naked eye. That makes it especially interesting for interactive prints, educational models, and projects where the colour response is part of the result.<\/p>\n<h3>Key Benefits at a Glance<\/h3>\n<ul>\n<li>Thermoactive colour change: Printed parts change from red to beige at about 30\u00b0C, creating a visible temperature-reactive effect.<\/li>\n<li>Easy PLA-style printability: Warp-free printing, excellent layer lamination, and no shrinkage after cooling.<\/li>\n<li>Strong visual appeal: The shiny finish and temperature response make this filament especially suitable for eye-catching, interactive prints.<\/li>\n<\/ul>\n<h3>Product Details<\/h3>\n<ul>\n<li>Brand: Spectrum Filaments<\/li>\n<li>Series: PLA Thermoactive<\/li>\n<li>Material: PLA with thermochromic pigment<\/li>\n<li>Colour: Red \/ Beige<\/li>\n<li>Surface finish: Shiny<\/li>\n<li>Diameter: 1.75 mm<\/li>\n<li>Density: 1.24 g\/cm\u00b3<\/li>\n<li>Net weight: 1000 g<\/li>\n<li>Temperature resistance: 55\u00b0C<\/li>\n<li>AMS compatibility: Yes<\/li>\n<li>RoHS &amp; REACH: Yes<\/li>\n<li>System: Spool<\/li>\n<\/ul>\n<h3>Recommended Printing Settings<\/h3>\n<ul>\n<li>Nozzle temperature: 190\u2013220\u00b0C<\/li>\n<li>Heated bed temperature: 0\u201345\u00b0C<\/li>\n<li>Recommended printing speed: 40\u2013250 mm\/s<\/li>\n<li>Cooling fan: up to 100%<\/li>\n<\/ul>\n<h3>Ideal Applications<\/h3>\n<p>Spectrum PLA Thermoactive Filament THERMOACTIVE RED is recommended for projects where it is important to identify equipment condition visually based on observable temperature-related effects:<\/p>\n<ul>\n<li>Educational projects<\/li>\n<li>Temperature-reactive models and indicators<\/li>\n<li>Temperature sensors<\/li>\n<li>Coatings for hot beverage mugs<\/li>\n<li>Coatings for kettles, thermostats, and other electronic devices<\/li>\n<\/ul>\n<h3>Why You\u2019ll Love It<\/h3>\n<p>Spectrum PLA Thermoactive Filament THERMOACTIVE RED combines easy PLA printing with a genuinely interactive visual effect. If you want a filament that does more than just hold shape &#8211; one that responds visibly to heat while still offering good surface quality, strong layer bonding, and warp-free printing &#8211; this is a very distinctive option for creative, educational, and temperature-aware 3D prints.<\/p>\n<p>&nbsp;<\/p>\n<h3 data-start=\"3496\" data-end=\"3512\"><strong data-start=\"3499\" data-end=\"3512\">Downloads<\/strong><\/h3>\n<p data-start=\"2091\" data-end=\"2313\"><a href=\"https:\/\/filaments.lv\/wp-content\/uploads\/2026\/03\/EN_TDS_Spectrum_PLA_Thermoactive.pdf\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" class=\"alignnone wp-image-395\" src=\"https:\/\/filaments.lv\/wp-content\/uploads\/2025\/08\/PDF_file_icon.svg-244x300.webp\" alt=\"by\" width=\"40\" height=\"49\" title=\"Buy Online |\"><\/a>Technical Data Sheet<\/p>\n<p data-start=\"2091\" data-end=\"2313\"><a href=\"https:\/\/filaments.lv\/wp-content\/uploads\/2026\/03\/EN_MSDS_Spectrum_PLA_Thermoactive.pdf\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" class=\"alignnone wp-image-395\" src=\"https:\/\/filaments.lv\/wp-content\/uploads\/2025\/08\/PDF_file_icon.svg-244x300.webp\" alt=\"by\" width=\"40\" height=\"49\" title=\"Buy Online |\"><\/a>Safety Data Sheet<\/p>\n","protected":false},"excerpt":{"rendered":"<p style=\"color: grey;text-align: left\"><small>\u2022 Thermoactive PLA<br \/>\n\u2022 Red to beige around 30\u00b0C<br \/>\n\u2022 Excellent layer bonding<\/small><\/p>\n","protected":false},"featured_media":3973,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[271],"product_cat":[198],"product_tag":[],"class_list":["post-3970","product","type-product","status-publish","has-post-thumbnail","product_brand-spectrum-filaments","product_cat-pla","product_shipping_class-filament-shipping","pa_att-product-type-filament","pa_color-beige","pa_color-red","pa_material-pla","pa_producer-producer-spectrum-filaments","pa_properties-thermoactive","pa_system-spool","first","instock","featured","taxable","shipping-taxable","purchasable","product-type-simple"],"acf":[],"ct_brands":[{"id":271,"name":"Spectrum Filaments","slug":"spectrum-filaments"}],"gallery_images":[3974],"tiered_pricing_type":"fixed","tiered_pricing_fixed_rules":[],"tiered_pricing_product_settings":{"layout":"default","base_unit_name":{"singular":null,"plural":null},"default_variation":null},"tiered_pricing_minimum_quantity":null,"tiered_pricing_roles_data":[],"tiered_pricing_percentage_rules":[],"tiered_pricing_maximum_quantity":null,"tiered_pricing_quantity_step":null,"_links":{"self":[{"href":"https:\/\/filaments.lv\/en\/wp-json\/wp\/v2\/product\/3970","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/filaments.lv\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/filaments.lv\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/filaments.lv\/en\/wp-json\/wp\/v2\/comments?post=3970"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/filaments.lv\/en\/wp-json\/wp\/v2\/media\/3973"}],"wp:attachment":[{"href":"https:\/\/filaments.lv\/en\/wp-json\/wp\/v2\/media?parent=3970"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/filaments.lv\/en\/wp-json\/wp\/v2\/product_brand?post=3970"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/filaments.lv\/en\/wp-json\/wp\/v2\/product_cat?post=3970"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/filaments.lv\/en\/wp-json\/wp\/v2\/product_tag?post=3970"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
