Filaween is a recurring filament-testing series on the JanTecEngineering channel where different 3D printing materials are put through structured benchmarks to compare real-world performance. The name blends 'filament' with a challenge-series format, and it has become one of the channel's signature content pillars alongside dedicated filament combination comparisons.

JanTecEngineering tested PHA filament — a bioplastic-based material — specifically for its ability to print without warping on a cold bed while still delivering tough mechanical results. The video highlighted PHA as a noteworthy alternative to conventional materials like PLA or PETG for users who struggle with bed adhesion and warping.

JanTecEngineering has covered print-setting and process-based approaches that produce smooth surfaces straight off the printer, avoiding the need for sanding or filler primer. A separate video specifically tackles the best no-sanding smoothing method for prints that do come out with visible layer lines.

JanTecEngineering demonstrated a mid-print pause technique where metal hardware — such as nuts or threaded inserts — is embedded directly into the model before the print resumes and encapsulates it. The method produces stronger assemblies than post-print heat-setting alone and is a practical tip aimed at functional, engineering-grade parts.

JanTecEngineering published a video titled '2026 Will Change 3D Printing' based on innovations shown at Formnext, the world's largest additive manufacturing trade show held annually in Frankfurt, Germany. Being based in Germany gives the channel a natural advantage for covering European 3D printing industry developments firsthand.

Yes — ABS and carbon fiber filaments are explicitly part of the JanTecEngineering testing lineup, alongside warp-free printing techniques for challenging materials. The channel regularly tests filament combinations rather than single materials in isolation, which is a differentiator from more casual 3D printing content.

JanTecEngineering has been sponsored by PCBWay, Ugreen, Fanttik, Brilliant, and Makera, among others. The sponsor mix reflects the channel's dual focus on precision 3D printing and electronics, ranging from PCB fabrication services to hardware tools and educational platforms.

Yes, JanTecEngineering is based in Germany and even lists an official German imprint on its website, as required under German law. Interestingly, despite the German origin, the majority of the channel's audience is in the United States, with Germany being the second-largest viewer country.

JanTecEngineering takes an explicitly engineering-first approach — the channel tagline is 'Print Like An Engineer' — focusing on material science, filament benchmarking, and electrical engineering rather than beginner tutorials or print showcases. The channel also runs well above the typical engagement benchmark for its category, suggesting a highly technical and invested audience.

JanTecEngineering has grown to over 40,000 subscribers on YouTube, placing it in the Micro creator tier. What stands out is its engagement rate, which runs significantly above the category median, reflecting a niche but highly active community of engineers and serious 3D printing enthusiasts.
