自助与制造

免费3D打印时间计算器 — 估算FDM和树脂（SLA/DLP）打印持续时间、耗材使用、卷轴消耗以及任何3D打印项目的总材料和电力成本。

免费3D打印耗材计算器——估算耗材成本、打印成本细分、电费、人工费、折旧以及任何卷轴上的剩余耗材。支持PLA、PETG、ABS、ASA、TPU、尼龙、PC等。

Free Arduino Pulse-Width Modulation (PWM) frequency calculator. Configure timer, prescaler, mode, and duty cycle — generates ready-to-paste Arduino C++ register setup code with waveform preview.

Free CNC Feed Rate and Speeds Calculator — compute feed rate, spindle RPM, surface speed, plunge rate, stepover, pass depth, and material removal rate for milling, drilling, and turning operations. Supports Imperial and Metric units with material presets.

Free CNC Spindle Speed (RPM) calculator — find the correct spindle speed for any tool diameter, cutting speed, and material. Includes feed rate companion output, HSS vs carbide comparison, material SFM reference table, and three calculation modes: Find RPM, Find Surface Speed, and Find Feed Rate.
