Flashforge Creator 5 Pro Owners Find Purge Waste Gets Sucked Into the Chamber Heater
A maker testing Flashforge's new Creator 5 Pro toolchanger found that purged filament strands fall past the chamber heater's intake and into its fan — and Flashforge pushed a firmware fix within 48 hours.

Green, Brown, Done: A Maker's Guide to Debinding and Sintering Metal and Ceramic Prints
The furnace does the real work in bound-metal and ceramic printing. Here's how green parts become brown, then dense final parts—and why most makers ship the hard steps out.

Oomwoo: An Open-Source, Fully Offline Robot Vacuum You 3D Print and Build Yourself
Maker's Pet is building Oomwoo, an Apache 2.0 3D-printed robot vacuum with Raspberry Pi, LiDAR, and ROS 2/Nav2 that runs entirely offline to dodge the cloud-hijacking bugs found in commercial vacuums.

Snap Fit Design for 3D Printing: Deflection Math, Tolerances, and Material Tradeoffs
Cantilever and annular snap fits are deceptively simple mechanisms that FDM printers struggle to reproduce reliably. Here is the geometry, deflection math, clearance strategy, and material selection logic to get them right on the first print.

Multi-Material FDM in 2026: Why Architecture Matters More Than You Think
Choosing a multi-material printer is really a choice between three distinct hardware architectures, each with fundamentally different tradeoffs in purge waste, contamination risk, and temperature compatibility -- and the wrong choice for your materials can make certain prints impossible.

Manual Color Swaps Without an AMS: G-Code Pause Commands in PrusaSlicer, OrcaSlicer, and Bambu Studio
Multi-color printing without a filament changer is entirely achievable using M600 and pause-at-layer commands. The slicer implementations differ in important ways, and getting the G-code sequencing wrong produces failed swaps, ooze blobs, or color bleed that contaminates the swap layer.

The Science of UV Post-Curing Resin Prints: Wavelength, Time, and Temperature
Post-curing is the most underestimated variable in MSLA and DLP resin printing. Get the wavelength, timing, and temperature wrong and your parts will be brittle, tacky, or dimensionally unstable regardless of how well they printed.

Variable Layer Height: How Adaptive Slicing Gets Better Surface Quality Without the Time Penalty
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 time.
