This slow process yields high molecular weight, excellent optical clarity, and the ability to produce genuinely thick blocks, which is exactly what an award needs. Extruded acrylic is manufactured continuously: molten acrylic is forced through a die and rollers to form sheets of consistent thickness at high speed and lower cost.

Extruded is softer and more prone to melting or chipping when worked, giving a lower-grade edge.<\/li>\n<li><strong>Embedments:<\/strong> Encapsulating objects, logos or 3D elements is a casting process, so it belongs to cast acrylic.

This is precisely why the awards industry uses the word <a href=\"https:\/\/fabit3d.com\/materials\/acrylic\/\">Lucite<\/a> as shorthand for high-quality cast acrylic.

Thin printed panels, backing layers, protective covers, lightweight display elements and cost-sensitive high-volume items all suit extrusion.

Because we run design, 3D printing and finishing in house in our Antwerp studio, we can be precise about this: we specify the right grade for each part of the piece rather than buying one sheet and making it do everything.

Cast also tends to have a very slightly higher softening temperature, which is why it machines more cleanly. When in doubt, thickness plus edge quality is the giveaway.<\/p>\n<h2>FAQ<\/h2>\n<p><strong>Are cast and extruded acrylic the same plastic?<\/strong> Chemically both are PMMA, but the manufacturing process changes clarity, thickness range and how well they machine, which is what matters for awards.<\/p>\n<p><strong>Is Lucite cast or extruded?<\/strong> Genuine award-grade Lucite is cast acrylic. That is the whole point of the material.<\/p>\n<p><strong>Can you embed our logo in extruded acrylic?<\/strong> No. Embedments require casting, so that work is done in cast acrylic.<\/p>\n<p><strong>Which will Fabit use for my award?<\/strong> Cast acrylic for the main piece in nearly every case, with extruded reserved for suitable secondary parts.
