Brims, Rafts & Supports — The RIGHT Way to Design 3D Printed Parts

Video Description

Learn More About Our Teleport Print On-Demand Service: https://www.slantpod.com/ This compilation brings together three of our most important engineering guides: how to properly design brims, rafts, and supports in CAD instead of relying on generic slicer features. Slicer-generated brims almost always create bottom-surface artifacts, slicer rafts warp and peel unpredictably, and auto-supports fail to touch critical features — which is why they cause so many print failures. In this video, we break down: • How to design clean, functional 0.2 mm brims, outer rings, mouse ears, and chamfers for perfect adhesion. • Why slicer-made rafts are fundamentally flawed — and how to engineer a reliable raft that prints flat, breaks away cleanly, and scales to production. • How to replace auto-supports with designed supports, crushable blocks, spacing offsets, support cones, fins, and custom support structures that guarantee the part prints as intended. If you want your prints to be cleaner, stronger, cheaper, and scalable, stop relying on slicer-generated “extras” and start designing these features correctly in CAD. 00:00 – Why Slicer Features Fail 00:17 – How to Design Brims Correctly 01:00 – Why Slicer Brims Cause Bad First Layers 02:30 – Proper Thickness for Brims (.2mm Rule) 04:00 – Best Shape for Brims (Circle vs Shape Outline) 05:50 – Chamfers for Clean Brim Removal 07:20 – When to Use Mouse Ears 09:14 – Brims Designed for Mass Production 09:54 – Why Slicer Rafts Don’t Work 11:00 – How to Design a Reliable Raft in CAD 12:20 – Correct Raft Spacing for Strong Adhesion 13:16 – Designing Breakaway Struts 14:30 – Patterns That Prevent Raft Warping 15:53 – Advanced Raft Interfaces (Velcro Breakaway) 17:52 – Why Auto-Supports Fail 18:35 – Support Thumbtacks for Small Features 19:58 – Designing Support Geometry Yourself 21:14 – Support Cones & Crushable Blocks 22:55 – Using Support Fins for Stability 24:55 – Removable Inserts for Bridges 28:08 – Exporting Solid Supports with Prusa SLA Mode Check Out Our Other Channels Slant POD: @SlantPrintOnDemand (3D Printing Business Tips) Tangled: @TangledTesting (3D Printing Materials & Testing) 🔗 OTHER LINKS 🔗 Get Affordable High-Quality Filament: https://tinyurl.com/bdcjjc9m Our Partner Designer: https://tinyurl.com/4aaz74pu Try Shapr3D (Use Code: Slant3d for 10% OFF): https://tinyurl.com/pc2r8wcv About Slant 3D 🏭 High-Volume 3D Printing: Scalability Meets Flexibility Slant 3D's Large-Scale 3D Print Farms utilize 1000's of FDM 3D printers working 24/7 to offer limitless scalability and unparalleled flexibility. Whether it's 100 or 100,000 parts, our system can handle it reliably, while still allowing for real-time design updates, ensuring products evolve with the times. This adaptability is key in today's fast-paced world. 🌿 Sustainable Manufacturing: Eco-Friendly Efficiency Embrace a system that drastically reduces carbon emissions by eliminating carbon-intensive steps in the supply chain, such as global shipping and warehousing. Our approach minimizes this footprint, offering a more sustainable manufacturing option. ⚙️ Digital Warehouses: Parts On-Demand Think of print farms as a "Digital Warehouse", meaning we can store your parts digitally on a server rather than physically on a shelf. parts are available on-demand, reducing the need for extensive physical inventory.
