Batch printing custom orders on one 3D printer

When orders start coming in, most new sellers print them as they arrive: one keychain, then the next, then a bag tag. Each print is quick, but each one also needs you to start it, watch the first layer, take it off and reset. The printer sits idle between jobs, and you never get a free evening.

Batching fixes this. Group your orders, print them in full beds, and do each kind of task once a day. Here's a routine that works on one printer and scales to a few.

Why batching works

• One setup per bed, not per order. Starting a print, checking the first layer and clearing the plate take the same time for one tag or twenty.
• Fewer filament swaps. Group orders by colour and you change spools a few times a day instead of every print.
• Longer unattended runs. A full bed can run overnight or while you're at work.
• Fewer mistakes. Doing all the checking at once, against one list, catches more errors than checking one piece at a time.

A daily routine

Morning: take orders and make files

Collect the last day's orders from every channel (Etsy, Instagram, WhatsApp, your website) into one list. For each one:

1. Copy the buyer's text into the design.
2. Send the approval picture.
3. Download the file once it's approved.

Name each file after the order, so you can match prints to buyers later. In the STLmint studio, this step takes a minute or two per order. For orders with a list of names, Bulk order (on the Seller plan) makes every file at once, numbered in list order.

Midday: build the beds

Group approved files by:

1. Colour pair, so one bed needs one filament setup.
2. Product type, since similar heights and sizes print well together.
3. Deadline, so urgent orders go on the first bed.

Arrange each group on the plate in your slicer. Leave space between parts for easy removal. Keep a note of which order is where; a simple sketch or a screenshot of the plate with order numbers written on works fine.

Afternoon and overnight: print

Start the longest or fullest bed when you'll be away the longest, such as overnight. Run shorter beds during the day when you can swap plates quickly.

Evening: check and pack

Take the prints off, check each one against its approved text, and pack it straight into its envelope with the label. Pack in the same order the files were arranged, so nothing gets mixed up.

Plan by plate, not by order

The question to ask is not "how long does this order take?" but "how many beds do I need today?". Work out:

• how many of each product fit on one bed,
• how long a full bed takes, and
• how many beds you can run in a day around your life.

That gives you your real daily capacity. When orders exceed it, extend your processing time instead of promising what you can't print.

Use a second plate

A spare build plate is one of the best investments for a small seller. While one bed prints, you clear and clean the other. Swapping plates takes seconds, so the printer is never waiting for you.

Make two-colour beds efficient

If you print two colours without an AMS, batching helps even more. A whole bed of raised-text tags changes colour at the same layer, so one manual filament change covers every piece on the bed. See two-colour name prints in Bambu Studio.

With an AMS, a full bed of the same colour pair also reduces the waste per piece, since each colour change purges once per layer, not once per part.

Keep failures from wrecking a bed

A full bed carries more risk: one part lifting can knock others over.

• Clean the plate before every bed. Fingerprints cause most adhesion failures.
• Watch the first layer of every bed. Most failures show up there.
• Put risky parts near the middle of the plate, where adhesion is most even.
• Keep spares of your best sellers. If a common item fails, a spare can go out on time.

When to add a second printer

When your printers are busy every hour you're awake and orders are still waiting, a second printer doubles your capacity without doubling your work, because file making, checking and packing are already batched. Run both on the same colours where you can.

Pricing reflects batching

Batching lowers your time per piece, especially on bulk orders. That's why a class of thirty tags can be cheaper per piece than one tag, and still more profitable. See how to price personalised 3D prints.

Common questions

Is it worth printing one order at a time for rush jobs? Sometimes, if you charge a rush fee. Otherwise, add it to the next bed.

How many orders should I batch? As many as fill a bed in the same colours. If a bed isn't full, add stock of your best sellers to the empty space.

How do I keep track of which print belongs to which order? Name files after order numbers, arrange them in a fixed order on the plate, and pack in that order. Bulk files from STLmint are already numbered in list order.
