Choosing 3D print finishing tools
Very few prints come off the plate ready to use. There are supports to remove, a brim to trim, strings to snip and the odd rough edge or hole to tidy. Working from coarse to fine saves time and avoids damage: cut away the bulk first, then trim and deburr, then smooth what is left. Each step has a tool that does it better than a kitchen knife ever will.
Post-processing workflow: the right tool for each step
| Step | Tool | Tip |
|---|---|---|
| Remove supports | Precision Flush Cutters (Pliers) or Precision Flush Cutter (Heavy Duty) | Keep the flat side of the jaws against the part so no stub is left |
| Reach supports in recesses | Stainless Steel Hook and Pick set | Lever supports out of holes and tight corners, pulling away from fine detail |
| Remove brims | Ceramic Trimming Knife / Deburring Tool Kit | Run the blade along the first layer rather than prying the brim up |
| Deburr edges and holes | Deburring Tool | Several light passes give a cleaner chamfer than one heavy one |
| Trim and detail | Hobby Knife with #11 Knife Blades | Cut away from your hands and change the blade once it drags |
| Smooth marks | Small File 10 Piece Set | Match the file shape to the surface, flat for faces and round for holes |
| Set heat inserts | Soldering Iron Adapter Kit for Plastic Heat Inserts | Let the heat do the work and press the insert in straight |
Using support removal tools, blades and insert tips
Flush cutters: standard or heavy duty
The Precision Flush Cutters have sharp, flush edges and a rubberised handle, and they are what we use to remove supports from our own printed models. The heavy duty YTH128 cutter has hardened carbon steel jaws and also takes care of wire, zip ties and filament ends, so it earns a place on an electronics bench too. Our guide to removing supports cleanly has more technique.
Ceramic knife or steel deburring tool
For brims, especially on prints with fine first layer detail, the ceramic trimming knife is easier to control than a classic metal deburring tool and more forgiving than a carving knife if you slip. That is why we recommend it for younger makers, with adult supervision. Choose the curved blade with handle only, or the 2-blade kit. The steel Deburring Tool comes with a plastic or aluminium handle and is made for steel, aluminium and plastic, so it doubles as a metalwork tool.
Setting heat inserts
The adapter kit uses brass adapters for M2 to M8 inserts and suits most soldering irons. The listed sleeve measurements are 24.8mm deep, 3.85mm inside diameter to fit over the ceramic heater element and 6.6mm outside diameter to fit the iron's collar, so compare those with your iron first. The tips run hot enough to burn instantly: use a stand, let the iron cool before swapping adapters and work with good ventilation. Stock up in our knurled brass inserts range and read our heat set insert sizing and installation guide.
Blade safety and replacement blades
- Always cut away from your body and keep your free hand behind the blade.
- A blunt blade needs more force and slips more easily, so swap it early.
- The Hobby Knife takes standard #11 blades, sold in packs of 5.
- The Deburring Tool includes one blade, and Noga Deburring Blades BS1010 come in a pack of 10. Check the product page to confirm the fit for your handle.
- Store knives and picks out of reach of children and dispose of used blades in a sealed container.
Once the part is clean, our sanding and painting guide takes it the rest of the way.

Finishing tool FAQs
What is the best tool for removing supports?
Start with flush cutters for most supports, cutting close with the flat side against the part. Use the hook and pick set for supports trapped in holes and recesses, where cutters cannot reach. Tidy any remaining nubs with a hobby knife, cutting away from yourself, then smooth the spot with a small file so the mark disappears.
Is the ceramic trimming knife a good choice for kids?
It is the finishing blade we recommend for younger makers, because it is more forgiving than a carving knife when a hand slips or loses grip. It is still sharp, so an adult should supervise. Teach children to cut away from their body, keep fingers behind the blade and put the knife down safely between cuts.
Do the spare #11 blades fit the hobby knife?
Yes. The Hobby Knife uses standard #11 blades, the same blades sold in the pack of 5, and it comes with one #11 blade to start. When changing blades, handle the old one by its back edge or with pliers, and check the new blade is clamped firmly before you make the first cut.
Which file set size should I choose?
The Small File 10 Piece Set comes in 140mm and 180mm versions, each with a range of file shapes and rubberised handles. The 140mm set is the one included in the finishing tool kit and is sized for fine detail, corners and holes. If you mostly work on larger parts, check the 180mm version on the product page.
