Powder-Coat Tumbler Walkthrough

A 30oz powder-coated tumbler with custom logo + name engraved on a rotary. The most-popular metal item in the laser community. Realistic Etsy retail: $30-45 single-piece (with batched template / saved settings to amortize labor); $20-30 bulk at 10+ pieces. Below those floors you're losing money, see the warning callout in the pricing section. Total time: ~8 minutes engrave + 5 minutes setup.

The order

"YETI-style 30oz black tumbler with my company logo on the front + name underneath."

Materials

• 1× powder-coated tumbler (Polar Camel: ~$4-9 wholesale via JDS Industries, varies by size; YETI: $40+ retail)
• Rotary attachment for your laser
• Calipers for measuring tumbler diameter
• Oramask 813 removable laser mask (for cleaner edges, optional, best on tumblers because it conforms to the curve and resists lifting under air assist)
• Microfiber cloth + isopropyl alcohol

Step 1: prepare the tumbler

1. Wipe tumbler with isopropyl alcohol, removes oils from manufacturing.
2. Caliper the diameter at the engrave area (typically 73-85mm for 20-30oz tumblers).
3. Inspect for defects, loose powder coat, scratches, dents. Skip if visibly defective.
4. Optional: mask the engrave area with Oramask 813 (conforms to tumbler curves) for cleaner edges.

Step 2: setup rotary

1. Power off laser.
2. Connect rotary cable to laser.
3. Place rotary on bed. Position so engrave area aligns with the laser head.
4. Mount tumbler, bottom edge of tumbler against rotary's chuck or roller-with-stop.
5. Verify tumbler doesn't slip or wobble. Add foam pad if needed.
6. Power laser back on.

Step 3: configure rotary in Lightburn

1. Lightburn → Tools → Rotary Setup.
2. Type: Roller (most common) or Chuck.
3. Steps per rotation: matches your rotary motor (typically 10000 or 20000).
4. Roller diameter: caliper your rotary's wheels.
5. Object diameter: enter your tumbler's caliper measurement. Critical.
6. Test: command exactly 360° rotation. Mark a reference dot. After rotation, dot should land exactly where it started.

Step 4: design the file

1. Lightburn workspace size = (tumbler circumference × engrave height).
2. For 30oz tumbler: ~250mm circumference, 80mm typical engrave height.
3. Drop in the customer's logo (vector preferred).
4. Add name underneath in selected font.
5. Position the design on the front-facing area of the tumbler.
6. For full wraparound design, span the entire circumference.

Step 5: layer settings: fiber MOPA

Lens	150mm (160-175mm field, gives clearance for tumbler height)
Speed	2000-2500 mm/s
Power	35-45%
Frequency	50 kHz
Q-Pulse Width	100-200 ns
Line interval	0.05-0.08 mm
Passes	1

Longer pulse widths (100-200ns) ablate the powder coat cleanly. Short pulses (under ~30ns) are for color marking on stainless and won't reliably remove powder coat, you'll get gray "ghost" marks instead of bright reveal.

Step 6: layer settings: CO2 (35-50W RF)

Lens	2" or 4"
Speed	400-500 mm/s
Power	25-40%
Line interval	0.10 mm
Air assist	LOW
Passes	1

Step 7: layer settings: diode (20W marketing)

Speed	2000 mm/min
Power	35-45%
Line interval	0.10 mm
Passes	1

Step 8: TEST FIRST

1. Engrave a small (15×15mm) test patch on the BOTTOM (hidden) area of the tumbler.
2. Inspect: should be clean white-on-color (powder coat fully ablated, metal showing through cleanly).
3. If gray instead of white: power too low. Increase 5%.
4. If powder coat is melted around edges: power too high or speed too slow.
5. Once test looks correct, proceed.

Step 9: focus and frame

1. Focus on the highest point of the tumbler (where the design will land).
2. Frame the design, the laser red dot traces the bounding box.
3. Verify the design lands within the engrave zone.
4. Adjust position if needed.

Step 10: run engrave

1. Open Preview. Verify time estimate (~5-8 min for typical logo + name).
2. Press Start.
3. Tumbler rotates as the laser engraves. Watch first 30 seconds for tone, smoke flares.
4. Engrave runs.

Step 11: post-engrave cleanup

1. Remove tumbler from rotary.
2. If masked: peel the Oramask, takes some powder coat dust with it.
3. Wipe engraved area with damp cloth + IPA.
4. For premium-finish work, follow with Enduramark BLU Powder Coating Residue Cleaner, pulls the chalky burnt residue at the engrave edges that IPA alone leaves behind. Crisp reveal instead of hazy.
5. Inspect under daylight LED. Engrave should be crisp white-on-color.

Step 12: package

1. Photograph for portfolio.
2. Place tumbler back in original box (or sleeve).
3. Wrap with tissue paper.
4. Add hand-written note.
5. Ship in cushioned box (tumblers can dent in transit).

Pricing breakdown

Tumblers are a volume product, NOT a high-margin one-off. The pricing math below shows two realistic paths: (a) the actual time-based cost if you billed every minute at $80/hr (which is too expensive for the market), and (b) the realistic Etsy retail and what you actually need to do per piece to make it work.

Material (Polar Camel 30oz wholesale)	$10
Setup + design (amortized across batch, saved Lightburn template)	2 min × $80/hr = $3
Rotary mount + frame	2 min × $80/hr = $3
Engrave time	5-8 min × $80/hr = $7-11
Cleanup + mask peel	2 min × $80/hr = $3
Packaging	3 min × $80/hr = $4
Total per-tumbler cost	$30-34
Etsy retail (single)	$28-45
Effective margin per piece	break-even to $15
Bulk wholesale (10+, save 50% on per-piece labor)	$18-25 cost, sells $25-35 each

Volume production tips

• Stock 20-50 tumblers in popular colors (black, white, navy, sage).
• Standard sizes: pick 2 standard tumblers (20oz + 30oz). Avoid one-off odd sizes.
• Variable text via CSV for bulk corporate orders.
• Foot pedal for production runs.
• 40+ tumblers per day feasible on a workflow-tuned setup.

Common pitfalls

• Wrong rotary diameter: design comes out distorted (stretched or squished). Re-caliper and re-test.
• Tumbler slips during engrave: design appears as broken lines. Add foam pad to rotary.
• Powder coat melts around engrave: power too high. Drop 5% and re-test.
• Gray engrave instead of white: coating not fully ablated. Increase power slightly.
• Different tumbler colors behave differently: black/dark colors typically engrave at higher contrast than light colors. Adjust per color.
