How to Price Your Time: Labor Costs for 3D-Print Sellers

Ask a 3D-print seller what their print cost and they'll tell you the filament price to the cent. Ask what their time cost and you'll usually get a shrug. Yet for most makers, labour is the largest hidden cost in the business — bigger than filament, electricity and wear combined.

This is the cost that decides whether you're running a business or an expensive hobby that happens to take in money. Here's how to figure out what your time is worth and actually charge for it.

"But the printer does the work"

This is the core misunderstanding. Yes, the printer runs unattended for hours — and no, you don't bill for those hours. That's machine time, and it's already covered by your electricity and machine-wear costs.

What you bill for is hands-on time: the minutes and hours you spend that the print couldn't happen without. On a print that takes the machine 8 hours, your hands-on time might be 25 minutes — and those 25 minutes are real, skilled labour that nobody else did for free.

What actually counts as labour

Add up everything you touch:

• Sourcing & modelling — finding or designing the model, fixing the mesh, preparing variations or personalisation.
• Slicing & setup — orienting the part, supports, settings, loading filament, swapping colors.
• Babysitting — checking first layers, monitoring tricky prints.
• Post-processing — removing supports, sanding, gluing multi-part assemblies, painting, adding hardware.
• Quality control — inspecting, re-printing rejects.
• Packing & shipping prep — wrapping, boxing, labels, the trip to the post office.
• Customer communication — answering questions, proofs, revisions, after-sale messages.

Each one is small. Together they're often 30 minutes to several hours per order — and completely invisible if you don't track them.

Setting your hourly rate

Your rate is a decision, not a discovery, but a few anchors help:

1. Start from a real wage. What would you have to pay someone competent to do this work? In many places that's $15–$30/hour for skilled hands-on fabrication and finishing. If you wouldn't get out of bed to do it for less, don't price it for less.
2. Account for the unbillable. Only a fraction of your working hours are billable to a specific order. Admin, learning, maintenance and marketing aren't free, so a working rate often sits above a plain hourly wage to cover them.
3. Respect your skill. Designing custom models or doing clean multi-part finishing is worth more than peeling supports. It's fine to have a higher rate for design work than for assembly.

Pick a number you can say out loud without flinching. $20/hour is a reasonable starting point for many hobby-scale sellers; raise it as your work and demand grow.

Two ways to bill it

Flat fee per job — simplest for repeat products. You know a particular print takes you ~20 minutes of hands-on work, so you add a fixed $7 labour charge and never think about it again. Great for a catalogue of known items.

Hourly — best for custom or one-off work where effort varies. Track the hands-on minutes and multiply by your rate. Essential for commissions, design work and complex assemblies.

Many sellers use both: a flat labour fee baked into standard products, and an hourly charge layered on for customisation.

Worked example

A custom desk nameplate, made to order:

• Tweaking the model with the customer's name: 10 min
• Slicing and color setup (it's two-tone): 8 min
• Support removal and a light sand: 12 min
• Packing and label: 8 min
• Messages and a proof image: 7 min
• Total hands-on: 45 minutes

At a $20/hour rate, that's $15 of labour — on a print whose filament might only cost $2. Leave the labour out and you've priced a $2 nameplate. Put it in and you've priced a $25–$30 product that's actually worth making.

"Won't charging for my time price me out?"

Two answers.

First, you're probably under-charging now, not over-charging. A price that ignores your time isn't competitive — it's unsustainable, and unsustainable shops burn out and vanish.

Second, you don't have to itemise labour to the customer. They see one price. What matters is that the number you quote includes your time, so that every sale moves your business forward instead of slowly draining it.

The free pricing calculator has a labour section with both modes — flat fee or hourly × hours — so you can fold your time into the true cost and the suggested selling price in one place. For the complete cost breakdown, read How to Price 3D Prints: The Complete Guide, and once you've set a price, see Etsy, Shopify & eBay Fees for 3D-Print Sellers so the platform's cut doesn't eat the labour you just charged for.

Key takeaways

• You bill hands-on time, not the hours the machine runs unattended.
• Labour includes modelling, slicing, post-processing, QC, packing and customer comms — usually 30 min to several hours per order.
• Set an hourly rate you can say without flinching (~$15–$30 for skilled hands-on work) and raise it over time.
• Bill it as a flat fee for standard products or hourly for custom work.
• Ignoring your time isn't a lower price — it's a hidden subsidy you pay your customers.
