    TPU 95A Infill Percentage and Flexibility: How Much Infill Makes a Phone Case Soft vs Rigid

    ByMike Reynolds April 29, 2026

    How TPU 95A infill percentage actually controls flexibility The TPU 95A infill percentage flexibility relationship is the most misunderstood print setting in flexible filament work. People assume infill is just structural — more material, more strength — and ignore that with TPU 95A the percentage you choose is the dominant lever for how the part…

    OctoPrint Smart Plug Power Control: PSU Control, Tasmota, and Auto Power Off After a Print

    ByMike Reynolds April 29, 2026

    What OctoPrint smart plug power control actually does OctoPrint smart plug power control is the workflow that lets OctoPrint turn your printer’s power supply on at the start of a print and off when the print is done — without you walking to the printer to flip a physical switch. The setup leans on three…

    Hatchbox PLA Sample Pack: Is It Worth It or Just an Expensive Way to Buy Plastic

    ByMike Reynolds April 29, 2026

    What is in a Hatchbox PLA sample pack and what does it cost The Hatchbox PLA sample pack is not a single SKU — Hatchbox sells several configurations and the question of whether the Hatchbox PLA sample pack is worth it depends entirely on which one you are looking at. The most common option is…

    ASA Annealing Process and Strength Gain: How Much, How Long, How to Avoid Ruining the Part

    ByMike Reynolds April 29, 2026

    What ASA annealing actually does to a 3D printed part The ASA annealing process strength gain conversation is full of numbers thrown around without context. People say “annealing makes parts 50% stronger” and skip past which strength, in which direction, and what trade-off they paid in dimensional accuracy. Annealing is real and worth doing for…

    Klipper Z Offset Auto Calibration With a Sensor: Probes, Commands, and Saved Configs

    ByMike Reynolds April 29, 2026

    Why Klipper Z offset auto calibration with a sensor matters more than people admit The Klipper Z offset auto calibration sensor workflow is the single biggest quality-of-life upgrade you can make to a 3D printer that already prints. A manual Z offset is a piece of paper, a lot of squinting, and a number you…

    All-Metal Hotend at 300°C: The Filaments You Can Actually Print at That Temperature

    ByMike Reynolds April 28, 2026

    What “all-metal at 300°C” actually buys you The standard PTFE-lined hotend that ships on most entry-level FDM printers is rated to about 240°C continuous. Above that, the PTFE liner inside the heatbreak begins to degrade — it releases fluorinated compounds (some toxic) and shrinks, restricting flow until the printer underextrudes or jams entirely. Replacing the…

    FDM vs Resin for D&D Miniatures: Which Method Captures the Detail You Need

    ByMike Reynolds April 28, 2026

    The detail gap is real, and it is bigger than people admit Tabletop miniature painters who have only ever printed with FDM and tabletop painters who have only ever printed with resin will both tell you their machine produces fine detail. They are both right within their reference set. The honest comparison is what you…

    PETG vs ASA for Car Parts Under the Hood: Which Survives the Engine Bay

    ByMike Reynolds April 28, 2026

    The engine bay is a torture test Under-hood automotive parts get a combination of conditions almost no other consumer environment produces simultaneously. Sustained operating temperatures sit at 70-90°C in air, with hotspots near the exhaust manifold and turbocharger reaching 130-180°C. Direct sunlight through a hood vent or open hood adds UV. Engine fluids splash routinely…

    ASA Filament Fume and Ventilation Requirements for Indoor Printing

    ByMike Reynolds April 28, 2026

    Why ASA gets called the worst-smelling common filament ASA is chemically a close cousin of ABS — acrylonitrile, styrene, and an acrylate ester replacing the butadiene rubber that gives ABS its characteristic smell. The acrylate substitution makes ASA much more UV-stable than ABS, which is the entire reason people print outdoor parts with it. But…

    Why this is the first OctoPrint feature people actually want OctoPrint is sold on remote access and webcam streaming, but the feature most users actually use day-to-day is the print-finished notification. Long prints sit on the bed cooling for hours if nobody knows they finished. The bed cools below the glass-transition temperature of the filament…
