What Is SLA 3D Printing?

SLA 3D Printing is a form of 3D printing that uses a laser or ultraviolet light source to harden a liquid resin into plastic. This style of printing works by layering the hardened plastic product to build the body of the three dimensional subject. SLA (stereolithography apparatus) technology was originally developed in Japan in the early 1980s as a system of 3D printing that could print functional products in a small amount of time. Today, SLA is still a widely popular form of printing and is often used in the  manufacturing of production materials and creation of high quality plastic models.

What is SLA 3D Printing used for?

  • SLA printing was originally created for the purpose of engineers producing high quality, plastic, prototypes in a time efficient manner. This is still a primary use of SLA printing.
  • This form of 3D printing has also gained popularity in the medical field. It is often used to create anatomically correct diagrams of the human body, used for education.
  • Many manufacturers also use SLA printing in the production of goods that have plastic components such as; jewelry, dentals tools, car parts, and prosthetics.

Cleaning SLA 3D Printing Machinery

SLA 3D printers generally consist of 4 parts; the resin tank, laser light source, perforated platform (building surface), and computer that controls the machinery and design. After a design has been completed, machine parts require some cleaning to ensure no resin is left to harden onto the surfaces. The best way to clean your SLA printing device is to wipe clean the surface with isopropyl alcohol (IPA).

For industrial and machine cleaning, Isopropyl alcohol (IPA) is preferred over other alcohol cleaning agents such as Methyl Alcohol, Ethyl Alcohol, and Butyl Alcohol, as IPA has an ideal evaporation rate and vapor density in comparison to these other alcohol cleaning agents. At Ecolink you can find high quality, isopropyl alcohol to clean your SLA printer, ensuring the cleanliness and longevity of your device.

The Differences Between IPA 99% and IPA 70%

IPA 99% or Isopropyl alcohol 99% is used in many applications as a powerful cleaning agent and method of preservation.

IPA 70% is not the same as IPA 99%. IPA 70% is found in common household products such as rubbing alcohol.

IPA General Information

  • Rubbing alcohol is a mixture of compounds, while isopropyl alcohol 99% is pure alcohol.
  • IPA 99% is more closely related to propanol, while rubbing alcohol derives from ethyl alcohol.
  • IPA 99% is not safe to ingest in any form and less common for consumer use, while IPA 70% as a product of ethyl alcohol can be found in common alcoholic beverages such as beer, wine, brandy, and whiskey.
  • Rubbing alcohol is a variant of denatured alcohol.
  • Rubbing alcohol has 70-95% ethanol, and can also be found as Isopropyl Rubbing Alcohol which contains around 95% ethanol.
  • IPA 70% is also less toxic and flammable than IPA 99% and evaporates more slowly.


IPA 70% can be more versatile than IPA 99%, because IPA 70% can be safely used for both industrial and household applications.

Both IPA 70% and IPA 99% are useful antiseptics and play an important role in at home and professional medical care.

This is one of the many reasons that while IPA 70% may be cheaper and more versatile than IPA 99% in some circumstances.

Why Choose IPA 99%?

Sensitive electronic devices, such as computer chips, and circuit boards, are best manufactured with IPA 99% because of its fast drying and low water content qualities.

IPA 99% is also a much more effective cleaning agent than IPA 70%, because of its extremely fast evaporation and the fact that it is pure, completely non denatured alcohol.

Though IPA 99% is flammable, it is the strongest alcohol cleaning agent available to ensure optimal medical and industrial cleaning.

IPA 99% can also utilized to remove most inks, pastes, oils, and other contaminants associated with machinery and printing.

High purity alcohol is much better for cleaning electronics, because that is what is used in the manufacturing of the product.

The important difference between IPA 70% and IPA 99% to remember is that the additional 30% of substance that comprises IPA 70 is not always water, there may be additives included that would not be safe for all cleaning applications.

This uncertainty is where the purity of IPA 99 truly comes in handy.

IPA 99’s extremely fast evaporation leaves no residue behind after any sort of application.

This is one of the many reasons why IPA 99 is a better cleaning agent than IPA 70.

Simply put, Isopropyl Alcohol 99% is a safe, pure, strong, and effective solvent and cleaning agent that is useful in the medical, household, laboratory, and manufacturing industries.

Isopropyl Alcohol: What is An IPA Cleaner?

Isopropyl alcohol (IPA) is a compound with the chemical formula C3H8O or C3H7OH or CH3CHOHCH3. Chemical elements that form the compound make it colorless — a desirable quality for cleaning minutely porous materials that could absorb color from cleaners — and highly evaporable, which makes it an optimal solution for cleaning soils from electronics.

Consequently, care must taken when using an IPA in an environment that has ignition sources. Fire hazard must also be considered when storing the popular cleaner. And workers who use IPA regularly can benefit from wearing respirators — and potentially other protective gear, depending on whether IPA is combined with other elements to create an IPA cleaner.

Classes of IPA

There are several classes of IPA based on intended use: industrial, cosmetic, pharmaceutical (USP), reagent, and electronic. At Ecolink, we specialize in IPA for general industrial use and cleaning electronics. Industrial grade IPA is primarily used as a solvent and cleaner. Electronic IPA is used in the same capacity, cleaning printed circuit boards (PCB) and flat panel displays (FPD), along with a many other electrical parts and apparatuses.

IPA Vs. IPA Cleaner

IPA from IPA cleaner is splitting hairs. IPA itself is a formidable cleaner; albeit, one with various purity levels that impact how and where it is used. The term ”IPA cleaner” commonly refers to cleaners containing the compound along with other active ingredients.

An IPA cleaner — as distinguished from pure IPA — commonly refers to cleaners using IPA to create industrial cleaner, such as IPA-based acetone, 2-bromopropane, and propene. However, because IPA with high a purity level is an excellent cleaner, organizations often use IPA alone, both as a general cleaner and a solvent for cleaning electronic components.

IPA Purity Levels

The efficacy and range of application for IPA depends on its purity. For example, pharmacy-grade rubbing alcohol, hand sanitizers, and disinfecting wipes commonly use a 60%–70% IPA solution in water. But industrial grade IPA frequently contains over 99% pure IPA.

The high purity enhances the compound’s natural qualities. Beneficial for cleaning electronics, evaporation rate increases. Another benefit is that high-purity IPA cleaner is affordable and more efficacious compared to other solutions (e.g., ethanol, n-butanol, and methanol). for some of the same applications.

IPA’s primary downsides are high flammability and high evaporation rate. As mentioned previously, the high evaporation is excellent for cleaning electronics; however, depending on the amount used, a special air filtration system and personal protective equipment (PPE) may be needed in the application environment.

IPA Solvent Uses: 4 Examples of Industrial Use

Isopropyl alcohol (IPA) has a wide variety of uses, from serving as a disinfectant for minor wounds to cleaning a variety of objects and surfaces in industrial settings. In this entry, we focus on the latter area of use, providing three examples of IPA solvent uses in industrial settings. The class of IPA we’re discussing is industrial grade IPA, whose purity exceeds 99%. This level of IPA density is generally unnecessary for commercial and residential IPA applications.

  1. Cleaning General Surfaces

IPA solvent uses include cleaning general surfaces. Types of metal and coated surfaces routinely found in industrial settings are generally unreactive to IPA. However, the cleaner is known to tarnish varnishes and ruin the erasability of dry erase boards.

Varnish and material coating dry erase boards aren’t common in industrial work areas, but IPA’s deleterious effect on these surfaces — an effect that depends partly on the purity of IPA — serve as notice that the compatibility of a material with IPA should be check before the cleaning operation commences.

  1. Cleaning Electronic Components

IPA solvent uses also involve cleaning electronic parts. The list is long, with some of the more popular IPA-cleaned electronic parts and apparatuses being contact pins in ROM cartridges,

magnetic tape, disk heads for legacy floppy disk drives, computer screens, optical disc drive lasers for CDs and DVDs, and IC packages.

What method of IPA deployment should be used to clean these and other components? The answer largely depends on the geometry of a component and where it’s situated in proximity to surrounding components. Due to aerosol particles’ ability to distribute evenly across intricate spatial configurations, IPA in aerosol form is optimal for parts that have complex geometries or are surrounded by parts that make them difficult to access.

  1. Minimizing Solvent Waste

From an industrial user’s standpoint, a potential drawback of IPA solvent uses is the fire hazard they entail. High-purity IPA has an an open cup flashpoint of 11.7°C (53.1°F; 284.8 K) and a closed cup flashpoint of 13°C (55°F).

IPA solutions can be diluted with water and made less flammable. But when it comes to solvent disposal, this isn’t quite the point. Rather, the high evaporation rate of IPA helps it evaporate before it enters the waste trap, especially when high-purity IPA is deployed as aerosol, or in the form of wipes. A potential benefit of IPA solvent use is reduced chemical waste disposal cost.
