Today Max and I speak with Xometry’s Greg Paulson again. This time we talk about scale in 3D printing. With manufacturing and real production seen as the new 3D printing frontier, companies are gearing up for products, services and the ever-popular “end to end solutions.” But, can we really do scale in 3D printing? And also should we want to do millions of low-cost parts? Or should we focus on scale but in limited verticals and applications? Can you do low cost and high-value parts at the same time? Or will we see specialized low cost and high regulatory regime players emerge? We don’t have all the answers but in a lively discussion, we talk about how far away we are from scale and what is needed. We hope you enjoy this episode and please do reach out to me should you wish to suggest a topic or guest.

Frequently Asked Questions
What is the best 3D printing filament for beginners?
PLA is the best starting filament — it prints easily at 190-220°C without an enclosure and produces good results. Once comfortable, PETG offers better strength and temperature resistance for functional parts.
How do I choose the right filament?
Consider the application: PLA for display models, PETG for functional parts, ABS/ASA for heat/sunlight exposure, TPU for flexible parts, and specialty filaments for engineering applications. Each has specific printer requirements.
What temperature should I print different filaments at?
PLA: 190-220°C nozzle / 50-60°C bed. PETG: 220-250°C / 70-80°C. ABS: 230-260°C / 100-110°C (enclosure needed). Nylon: 240-270°C / 70-90°C. Always check manufacturer recommendations for specific brands.
