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.

🏭 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.
