Enviroset 3D Jet Resins from HA
Robust 3D Printing Resins Producing Remarkable Results

HA International has been supplying binder and activators specifically designed for 3D sand printing for over five (5) years, which means we have been developing superior furan resins, including those for all 3D printers for sand core and molds, for more than 20 years. Our low viscosity resin has been specially manufactured for use in all sand core and mold 3D printers, for use with all types of metals.

When it comes to experience with 3D printing of sand and mold cores, our reputation has stood the test of time.

HA delivers superior print head compatibility and longevity with the dimensional accuracy 3DP casting customers demand. And, our unique combination of binder and select activators provide the fastest part extraction and ease of cleaning. And... our resins are priced more affordably than others on the market.


  • Increased productivity – resin helps print heads to last longer
  • Reduced labor – printed molds and cores are cleaned faster
  • Reduced costs – resin is very economical

Optimized Feeding Systems

It is well known that metals change volume during solidification. This volume change must be compensated during solidification otherwise shrinkage defects can occur in a casting, making it unusable for its stated purpose.

This has been solved through the use of adding a metal reservoir commonly known as a "feeder" the purpose of which is to supply liquid metal to the casting as it cools and solidifies.

As this technology has developed and been improved, newer types of feeder materials have become available, including combinations of exothermic-insulating and highly exothermic compositions. The choice of material depends upon the application.

An Interesting Approach to the Product Installation Process

I always have believed that to successfully implement a new resin system in an existing or new customer, it is necessary to take into consideration four important factors: Materials, Methods, Manpower, and EH&S. The first three represent a three-sided equilateral triangle, which in turn is being supported by safe practices and products. If any of the sides of the triangle are unbalanced, the chances of carrying out a successful implementation could be compromised. Any substantial deficiency of any of the 3 M's (Materials, Methods, Manpower), will require that the other two be challenged at a higher degree.

EcoLite refractory coatings feature the latest light-off / fast drying technology. By using VOC-Exempt solvent packages, the flexibility and advantages of solvent based coatings can now be realized while minimizing the permitting of VOCs. Whether lowering the VOC impact of alcohol coatings or increasing productivity of water based coating applications, EcoLite coatings provide a unique value to today's foundry.

Environmental stewardship: NOT JUST A TREND

The metalcasting industry has a great reputation when it comes to recycling. However, environmental stewardship involves more than recycling. Using materials with more advanced environmental benefits is where metalcasters can take a leading role to mitigate some of the environmental challenges they face while creating a healthier and safer work environment.

Understanding 3D Sand Printers and Binder Technologies

AM for cores and molds is gaining popularity because of the flexibility and complexity it offers in production, but productivity is critical to the long-term prospects

Additive manufacturing of sand cores and molds has attracted the attention of many foundries in recent years due to the process' unique ability to form core shapes that cannot be manufactured using conventional coremaking techniques. It does this by a process called "binder jetting": a reactive resin, most commonly, a furfuryl alcohol-based (FA) binder formulated for the application is deposited on a substrate. Typically, the substrate is a silica sand that has been pretreated with an acid catalyst, but it can be a number of other aggregates used in metalcasting, such as zircon and synthetic ceramics.

HAI Feeder Technology - Powered by Chemex

Finally, casting feeder technology that produces a shrinkage free casting while decreasing production costs on even the most complex designs.

Patented Tele-feeder Systems are especially ideal for complex castings including intricate designs and rapid molding processes. This technology uniquely allows feeder placement in previously inaccessible locations.

Significant Benefits:

  • Increases productivity with higher yield and faster cleaning time

  • Increases quality with reduced casting scrap and rework

  • Reduces environmental footprint with reduced energy

  • Expands the locations for feeder placement

  • Reduces surface defects with fluorine-free material

Evolution of Foundry Shell Sand for Today's Foundry

Simple Solutions That Work - (Issue 9, September 2018)

The Shell Sand process or "Croning" process was invented by Dr. Johannes Croning in Hamburg, Germany in 1944. This process is the oldest core and mold making technology that utilizes synthetic resins. Although many additional sand core and molding making technologies have since been introduced, the Shell Sand process is still a very effective core and molding process today.

Doug Trinowski Presents Hoyt Memorial Lecture

April 2017

MILWAUKEE, Wisconsin - (April 2017) - The American Foundry Society’s Hoyt Memorial Lecture was established in 1938 and has been a highlight of every AFS Metal Casting Congress since then. The chosen lecturer is selected for his/her contributions to the metal casting industry and this year HA International’s Douglas Trinowski was given the honor of presenting the lecture. His presentation was on “The Power and Need for Research in Metalcasting”. Doug gave an engaging presentation on past metalcasting research that has led to measurable improvements in the industry and focused on the need for continued research as supported by AFS. He also outlined many examples of critical needs and challenges in the industry that can only be resolved with organized research. Finally, Doug focused some time on how research is conducted in various countries and the need for improving the technical transfer process.

Doug is the former Vice President of Research and Development for HA International and the current Director of Special Projects. We are a successful organization today due in large part to the leadership of Doug and the contributions of him and his team over many years.
