3D printing has shifted from being a niche hobby to a practical tool for prototyping, repairs, and small-scale manufacturing. Home workshops now include more than just the printers themselves. A growing range of specialized tools helps improve print quality, streamline post-processing, and maintain consistent performance. These accessories have become important for hobbyists and professionals working from home.
Precision Digital Calipers
Accurate measurement is critical for designing and verifying 3D-printed parts. Precision digital calipers allow users to measure internal and external dimensions with high accuracy, typically to within 0.01 mm. They are used both before printing, to ensure designs match intended tolerances, and after printing, to confirm output accuracy.
Models with stainless steel construction offer durability, and digital readouts simplify reading measurements. Some connect to computers via USB or Bluetooth for data logging, useful for documenting build results over time.
These calipers have become standard in home workshops as more users produce functional parts that require reliable fitting with other components.

Flexible Build Plates
Removing prints from a build surface can be challenging without damaging the part or the printer. Flexible build plates solve this problem by allowing users to bend the plate to release prints easily. They typically use a magnetic base for quick attachment and removal.
These plates are available for both FDM and resin printers, with surfaces designed to promote good adhesion during printing while still allowing for easy part removal afterward. They reduce the risk of damaging delicate parts during removal.
Their convenience and reduction in failed prints have made them a common upgrade for home 3D printers.

-
Works with multiple printer types
Cons
-
Can wear out over time
-
Some surfaces require periodic cleaning or replacement
Resin Curing Stations
For resin printers, proper curing is essential to achieving final material strength and stability. Resin curing stations use UV light to harden prints after they have been washed, ensuring that the material reaches its optimal performance.
Modern curing stations often combine washing and curing functions in one unit, streamlining post-processing. Adjustable timers and rotating platforms help achieve even curing. These tools are particularly important for functional resin parts used in mechanical assemblies.
Their growing adoption reflects a move toward professional-level finishing processes in home environments.
Key features
-
UV curing for resin prints
-
Combined wash-and-cure systems available
-
Adjustable timers and rotation for even exposure
Pros
-
Improves final strength and durability
-
Consistent curing results
-
Reduces manual handling time
Cons
-
Adds to initial setup cost
-
Requires space on the workbench
Filament Dryers
Moisture in filament can cause poor layer adhesion, stringing, and other print defects. Filament dryers address this by heating the spool at controlled temperatures to remove absorbed moisture. This is particularly useful for hygroscopic materials like nylon and PETG.
Some dryers double as storage containers, keeping filament dry between prints. Others allow printing directly from the dryer, reducing exposure to ambient humidity.
For those working in humid climates or with moisture-sensitive filaments, this tool can significantly improve print reliability.
Key features
-
Adjustable heating for different materials
-
Direct printing from dryer option
-
Sealed storage for filament protection
Pros
-
Reduces failed prints
-
Extends filament shelf life
-
Works with multiple filament types
Cons
-
Requires electricity during use
-
Larger units can take up bench space
Nozzle Cleaning Kits
Consistent extrusion is essential for print quality, and clogged nozzles can halt a project entirely. Nozzle cleaning kits typically include fine needles, brass brushes, and solvent-safe tools for clearing blockages and removing carbonized material.
Some kits also include spare nozzles, making it easier to swap out damaged ones. Regular cleaning extends nozzle life and ensures that extrusion remains smooth.
Given how common nozzle clogs are in home 3D printing, these kits have become a staple for maintenance.
Key features
-
Cleaning needles and brushes
-
Solvent-safe tools
-
Replacement nozzles included in some kits
Pros
-
Maintains consistent extrusion
-
Extends nozzle lifespan
-
Low-cost maintenance solution
Cons
-
Requires care to avoid damaging nozzle tips
-
Does not solve deeper extrusion system issues
Part Removal Tools
While flexible build plates solve many removal problems, certain prints still require more delicate extraction. Part removal tools include thin, tapered scrapers for FDM prints and specialized spatulas for resin prints.
These tools are designed to get under prints without damaging the surface or the part. Ergonomic handles improve control, and some models use stainless steel blades for durability.
Keeping a set of dedicated removal tools reduces the risk of damaging prints or build surfaces.
Key features
-
Thin, tapered edges for precision
-
Ergonomic handles
-
Stainless steel or coated blades
Pros
-
Reduces damage during removal
-
Works for both resin and FDM prints
-
Improves safety over improvised tools
Cons
-
Blades can dull over time
-
Requires proper storage to avoid injury
Digital Design Tablets
For users creating custom models, digital design tablets provide a more natural drawing and sculpting experience compared to a mouse. These devices connect to CAD or 3D modeling software, allowing precise control over lines and shapes.
Pressure sensitivity and programmable buttons streamline design workflows. They are particularly useful for creating organic shapes or detailed textures in models intended for printing.
As more home users move from downloading models to designing their own, these tablets are becoming more common.
Key features
-
Pressure-sensitive stylus
-
Compatibility with CAD and 3D modeling software
-
Programmable shortcut keys
Pros
-
Improves design precision
-
Speeds up modeling workflow
-
Comfortable for extended use
Cons
-
Learning curve for new users
-
Higher cost for professional models
Heat Guns
Heat guns are used in post-processing for smoothing prints made from materials like PLA and ABS. By carefully applying heat, small imperfections can be removed, and seams blended. They are also used to soften parts for slight reshaping.
Variable temperature controls and focused nozzles improve safety and precision. However, excessive heat can deform parts, so control is important.
Heat guns are inexpensive but effective tools that enhance the finish of printed parts when used correctly.

Final Considerations
The tools now accompanying home 3D printing setups are evolving as quickly as the printers themselves. From precision measurement to material preservation and post-processing, each of these tools serves a specific role in ensuring consistent, high-quality output.
For those building or expanding a home workshop, investing in a combination of measurement, maintenance, and finishing tools will yield better prints and reduce downtime. The shift toward professional-grade accessories in home environments shows that the technology is maturing and that users are prioritizing quality and reliability alongside creativity.
