  Software · 2026-06-25

  The slicer landscape in 2026 has fragmented along clear lines: ecosystem loyalty, calibration depth, and hardware compatibility each favor a different tool, and the right answer de…

• 3D Printing on the Water: Marine Applications, Material Selection, and the Limits of What FDM Can Build
  Industry · 2026-06-21

  From replacement cleats to instrument housings and full hull experiments, 3D printing is finding a permanent role in marine environments. ASA and CF-PETG are doing real work; full …

• TPU vs TPE vs TPC: Choosing the Right Flexible Filament for the Job
  Materials · 2026-06-21

  Flexible filaments are not interchangeable. TPU, TPE, and TPC differ substantially in hardness, chemical resistance, print temperature, and long-term fatigue behavior. Choosing the…

• Meshmixer for 3D Printing: Repair, Hollow, and Orient Files the Easy Way
  Software · 2026-06-20

  Meshmixer is free, actively maintained, and handles the mesh repair and hollowing workflows that slicers handle poorly. Here's the toolkit every maker should know.

• 3D Printing on the Farm: Custom Parts, Precision Agriculture, and Sensor Housings
  Industry · 2026-06-20

  Agricultural equipment breaks in ways that manufacturers don't support with spare parts. 3D printing is filling the gap for everything from planter parts to custom drone mounts.

• 3D Printing and Intellectual Property: What Makers Need to Know About Copyright and Patents
  Business · 2026-06-20

  Printing a copyrighted character for personal use, selling prints of patented designs, and sharing STL files all have different legal implications. Here's what the current law actu…

• High-Flow Filaments: What They Are and Why Your Speed Printer Needs Them
  Materials · 2026-06-20

  At 300+ mm/s, standard PLA becomes the bottleneck — not the motion system. High-flow filaments are formulated to melt faster, enabling speed printers to reach their actual potentia…

• Elegoo Saturn 4 Ultra Review: High-Resolution Large-Format Resin at a Consumer Price
  Printers · 2026-06-20

  The Saturn 4 Ultra combines a 12K mono LCD with a 218×122×260mm build volume and a tilt-release mechanism. It's currently the best large-resin value proposition on the market.

• Prusa MINI+: The Case for a Smaller, Smarter Second Printer
  Printers · 2026-06-20

  At 180×180×180mm build volume, the MINI+ won't replace a full-size machine. But its compact footprint, consistent quality, and open-source firmware make it one of the most practica…

• Variable Layer Height: How Adaptive Slicing Gets Better Surface Quality Without the Time Penalty
  Guides · 2026-06-20

  Adaptive or variable layer height lets slicers use thin layers where they matter and thick layers where they don't. The result is better surface quality at nearly the same print ti…

• Living Hinges and Flex Joints: Designing Bendable Features Directly Into FDM Prints
  Guides · 2026-06-20

  A living hinge folds thousands of times without a fastener. In FDM, making it work requires specific geometry, the right material, and a print orientation that isn't obvious.

• Designing for Strength: How Wall Count, Infill, and Print Orientation Determine Part Performance
  Guides · 2026-06-20

  A 3D printed part's strength isn't fixed at purchase — it's determined by your design choices, slicer settings, and how you orient the model. Here's what actually matters.

• How Hollywood Uses 3D Printing for Props and Practical Effects
  Industry · 2026-06-20

  From hero props to breakaway stunt duplicates, additive manufacturing has fundamentally changed how film and TV productions fabricate physical objects on set.

• Multi-Part Prints: Alignment Pins, Snap Fits, and Gluing Strategies
  Guides · 2026-06-20

  When a model won't fit on your bed or benefits from separate material properties, multi-part printing is the answer. Here's how to design joins that actually hold.

• Building a Voron Trident: What First-Timers Need to Know Before Ordering Parts
  Printers · 2026-06-17
