Guide to post-processing for 3D printed parts

Post-processing is a highly important part of the additive manufacturing ecosystem, though it is one of the more hidden facets of 3D printing. This guide covers the main 3D printing post-processing steps that exist and provides a general selection of well-regarded solutions on the market.

What is post-processing in 3D printing?

In most situations, production of a 3D printed part doesn’t end when the part comes off the print bed. Some parts emerge from the 3D printer with a very rough surface texture and temporary support structures still attached. For all intents and purposes, these parts are still unfinished and must undergo post-processing.

Post-processing is a group of techniques used to turn unfinished 3D printed parts into something usable, displayable, or marketable. Some of these techniques (surface finishing, coloring, etc.) are universal, while some (curing, sintering, etc.) are particular to specific technologies. All of them guide a printed part towards its final form.

The importance of post-processing is on the rise. As 3D printing has become more widely used as a production tool, the demand for high-quality post-processing has increased, and today’s printed parts look and feel better than ever before.

This article looks at the most important aspects of post-processing 3D printed parts, including the increasingly important role of automation, and includes a comprehensive product guide for additive manufacturing (AM) post-processing systems.

Post-processing workflow

The nature and extent of post-processing depends on several factors, such as the chosen 3D printing technology and the end use of the printed parts. Some projects may require several stages of post-processing, while others may not require any at all.

As such, the following post-processing techniques can be used in many combinations.

We have listed them in the order in which they might generally take place, beginning with cleaning processes and concluding with part inspection.

Support removal and cleaning

Support removal

3D printers can create extremely complex shapes. However, parts with overhanging sections sometimes require printed supports, which prevent the structure from collapsing.

Supports need to be removed after printing. In some cases — usually when the supports are made from the same material as the printed object — this involves breaking the supports away manually or with pliers. These kinds of supports are known as insoluble supports.

However, some 3D printers can print support structures in a dedicated support material, which can later be dissolved in liquid for a cleaner and faster breakaway. These are known as soluble supports.

Powder removal

3D printing processes like SLS use powder as a printing material. When a part is finished, it may have a powdery residue on the surface which needs to be removed.

Although powder can be removed manually by sweeping and vacuuming, it is faster and more effective to use a dedicated machine, especially during large-scale production. Powder removal systems, many of which use compressed air, may rotate or vibrate the printed parts in order to accelerate de-powdering.

Some de-powdering systems also use an inert gas chamber to nullify a potentially explosive atmosphere that can be caused by reactive AM powder materials like titanium, while most have filters to prevent workers from inhaling dangerous particles.

A few desktop SLS 3D printer manufacturers like Sinterit sell post-processing accessory bundles with their printers.

Part washing

Resin 3D printing processes like SLA can leave a sticky residue on printed parts. This excess resin must therefore be removed before further post-processing, testing, or end use.

It can be removed manually by soaking the printed parts in a solvent like isopropyl alcohol, but there are also machines, such as the Formlabs Form Wash, that can perform this soaking in a programmed and controlled manner.

To comprehensively remove excess liquid resin, the part may need to be gently shaken in the solvent bath, and sequential soaking in fresh baths may also be required.

PostProcess Technologies FORTI post-processing support removal

Annealing, curing, and sintering

Heat treatment and annealing

Most metal 3D printed parts require heat treatment after printing. This helps improve layer fusion and gives desirable mechanical properties to the metal. Under certain conditions, heat treatment can also remove contaminants such as oxide film from the surface of the part.

Heat treatment can sometimes take place within the AM system itself. The miniFactory Ultra, for example, can anneal printed parts made from thermoplastic materials like PEEK or PEKK, heating them up to 250°C. Standalone units also exist for the process.

In rare cases, it is possible to use High-Pressure Heat Treatment (HPHT), applying pressure up to 30,000 psi and temperatures of up to 2,200°C for the heat treatment of high-performance materials.

The machines eliminate pores and remove defects from metal AM parts, and Quintus Technologies says its HIP systems are the safest, most reliable and durable pressure containment systems ever designed.


Most resin 3D printed parts need to be further cured under UV lamps as a whole before they are fully hardened and ready for use. This is called post-curing.

SLA specialist Formlabs offers a dedicated post-curing machine called the Form Cure, while AM innovator Carbon has integrated UV curing into its CLIP 3D printing process. Most resin 3D printer manufacturers also sell their own curing machines and accessories.


Metal and ceramic AM processes often require sintering after printing is complete, with parts emerging from the printer “green” and not yet ready for use. This is also the case for clay 3D printing.

Metal binder jetting 3D printers, such as the ExOne X1 25Pro, require the use of a debinding and sintering furnace to burn out the polymer adhesive from parts. This leaves behind only the metal particles, which sinter together to make the parts stronger.

All-in-one solutions like the Desktop Metal Production System come with their own furnace, while some manufacturers sell proprietary equipment separately.

Furnaces may also be used when using 3D printed parts as wax casting patterns. The printed pattern is burnt out once the cast has been formed, allowing new parts to be cast. This technique is often used in the jewelry industry.

Surface finishing: subtractive methods


An important surface finishing treatment for FDM parts is chemical or vapor smoothing, which reduces the appearance of layer lines — an unsightly feature that may be visible even at high printing resolution.

However, smoothing is difficult to carry out with precision, and it can damage delicate features of a print by removing too much material.

Chemicals like acetone can be used to effectively smooth FDM parts made from PLA or ABS.

Sanding is a manual finishing process used on many manufactured parts, including FDM 3D prints.

It can be beneficial to start with a coarse sandpaper for removing chunks of excess material, before moving to a finer paper to smooth the entire surface of the part.


Tumbling is a method of smoothing the surface finish of printed parts. It works by rotating a printed part with an abrasive media in an enclosed drum, usually for several hours.

Abrasive media can include steel pieces, ceramic pieces and even organic matter like nut shells.

Possible finishing techniques include grinding, rounding, deburring, surface smoothing and high-gloss polishing.

Surface finishing: additive methods


Printed parts can be given a high-gloss look by spraying them with a liquid coating of a substance like polyurethane.

Glazed epoxy coatings can also be applied with a paintbrush.

Metal plating

For shiny metallic surface finishing, metal plating can be added to 3D printed parts, either via electroplating or electroless plating.

During the electroplating process, parts are immersed in a solution of water and metal salts and subjected to an electrical current. A metal coating quickly forms around the printed part. It is similar to the process of anodization — though anodization is not usually recommended for 3D prints.

Electroless plating uses chemicals instead of electricity and takes longer to complete.

Infiltration is a common post-processing technique for binder jetting 3D printed parts.

Like sintering, it requires a furnace to burn out any polymer binder. But instead of sintering the remaining metal particles, a new metal material is introduced to fill the porous spaces in the part.



Dyeing is a coloring process frequently used to color nylon parts or other prints made using jetting, binding or sintering processes.

Color can be added by hand using a tub of hot water, but several machines exist for dyeing printed parts in a controlled manner.

White parts are most suitable for dyeing.

Automated for unsupervised operation, the DY 130 purportedly offers half the cost per part of comparable automatic dyeing equipment.

Priming and painting

While dyeing is best suited to parts made from powder, paint can be applied to a wider variety of printed materials.

After a layer of primer is applied, paint can be added to a 3D print using a brush or spray, or with a dedicated coloring machine.


An important final step in the post-processing procedure is part inspection.

In addition to visual inspection, parts can be analyzed using a tools such as Coordinate Measuring Machines (CMM), which precisely measure the dimensions of a finished part.

Alternatively, metrology 3D scanners can be used to perform a similar function at higher speed and precision, all while providing several more million 3D points. It is even possible to automate part inspection thanks to robotic arms and adequate 3D software.

Why post-process 3D printed parts?

3D printed parts can be post-processed for functional or aesthetic reasons, or both. Rough prototypes may not require post-processing, but virtually all other prints require some degree of treatment.

Functional reasons

  • Strength: Processes like sintering and debinding can turn weak and brittle metal parts into sturdy ones
  • Water or UV resistance: Smoothing techniques make part surfaces less porous and increase water and UV resistance
  • Tolerances: Precisely controlled post-processing techniques like CNC machining can tighten tolerances for critical parts
  • Thermal stability: Processes like annealing can improve the heat resistance of a printed part to increase its mechanical reliability
  • Decreased friction: Processes like polishing can improve the smoothness of parts that need to interact with other parts with minimal friction

Aesthetic reasons

  • Smoother appearance: Surface finishing treatments can reduce the rough appearance of printed parts
  • Softer touch: Smoothing and polishing makes 3D printed parts soft to the touch, which may be desirable for ergonomic consumer products
  • Controlled gloss: Post-processing allows the manufacturer to determine and control a part’s level of glossiness
  • Eliminate signs of manufacture: Techniques like sanding can be used to remove layer lines and disguise a part’s machine of origin — ideal for prototypes of parts that will ultimately be injection molded
  • Color options: Dyeing and painting allows parts to be made in a wide range of colors

Post-processing and automation

Most post-processing — from support removal to polishing and painting — is still carried out manually, which lengthens the time required to bring a part to completion.

In order for AM to remain a viable production solution, more manufacturers need to adopt automated post-processing solutions that are capable of quickly processing parts in batches or in rapid sequence. Dedicated additive manufacturing MES software solutions exist to help automate AM workflows.

Automating post-processing is crucial for obtaining positive ROI, since it reduces manual labor and decreases time-to-market. AM equipment providers already recognize this fact, as can be seen from the wide array of automated post-processing solutions available.

Manufacturers may decide that their workflow is suited to separate post-processing machines for each task, while others may favor a compact, all-in-one solution like the PostProcess Hybrid DECI.

Incorporating automated post-processing solutions into the production line also has other benefits. For example, eliminating manual post-processing reduces safety hazards associated with the accidental ingestion of powders and the handling of sharp objects.


What is post-processing in 3D printing?

Post-processing is a group of processes used to improve a 3D printed part after it leaves the printer. The term covers methods of cleaning, smoothing, augmenting, and coloring 3D printed parts.

How do you post-process PLA?

PLA parts made on a 3D printer may require several forms of post-processing, including support removal, sanding, smoothing and painting. For homemade prints, sanding requires the least equipment.

Is post-processing always necessary?

Rough prototypes may not require post-processing, but very few 3D printers claim to fabricate parts that are ready for use right from the print bed. Your chosen 3D printing technology determines the amount of post-processing required.

Why don’t 3D printers automatically perform post-processing?

Some industrial 3D printers incorporate some forms of post-processing, especially large powder-based machines. However, many post-processing techniques require a large work area in addition to substances like chemical solvents, blast media, and colorants. It would not be feasible to employ these techniques within the printer envelope, as integral parts of the printer could get damaged.

Can 3D printers print in color?

Yes, full-color 3D printers exist and can directly 3D print in color.
