Side-by-side comparison

Three methods for multi-sided reference: true workshop cost vs common service-quote logic. Tiny jobs often hit the minimum fee.

Workshop detailed

NT$ 172.1

Detailed: filament + power + amortization + labor + post-process, then failure buffer and markup.

Machine-hour quote

NT$ 437.5

Machine-hour = filament + hours × service hourly + labor + post-process, then max with minimum fee.

Service per-gram

NT$ 562.5

Service per-gram = g × NTD/g + labor + post-process, then max with minimum (quote rate, not raw filament).

Workshop detailed estimate

Amortized hourly: NT$ 7.6/h · Est. energy: 1.4 kWh · Machine-hour quote: NT$ 80/h · Service per-gram: NT$ 5/g

  • Detailed: filament + power + amortization + labor + post-process, then failure buffer and markup.
  • Electricity = (W ÷ 1000) × hours × rate. TW residential tiers ~NT$1.8–6/kWh; site default NT$5.
  • Failure buffer = cost ÷ (1 − failure rate) so successful jobs cover reprints.
  • Machine-hour = filament + hours × service hourly + labor + post-process, then max with minimum fee.
  • Service per-gram = g × NTD/g + labor + post-process, then max with minimum (quote rate, not raw filament).

Pricing reference

Formula summary

  • Detailed: ((filament+power+amort+labor+post) ÷ (1−fail%)) × (1+markup%).
  • Machine-hour: max(filament + hours×hourly + labor + post, minimum).
  • Service per-gram: max(g×NTD/g + labor + post, minimum). TW FDM PLA bureaus often ~NT$3–10/g, NT$50–150/h, ~NT$200 minimum.
