Every injection mold manufacturer aims to spend less money and achieve optimal results, and 3D printing has become possible.

What will you learn?

In this blog, Go4Mould explores how 3D printing transforms the injection molding industry.

What Is 3D Printing For Injection Molding?

Generally, injection molds are produced using Computer Numerical Control machining or regular metalworking procedures that take a critical measure of time and require significant expense. Nevertheless, through 3D printing, the manufacturer can quickly design and produce the molds at a much lower cost than in the traditional way.

This is handy in low-volume production runs, such as the prototype development and production stages.

Using 3D printing for Injection Molding

Here’s how you can integrate 3D printing into Injection Molding.

Understanding 3D-Printed Molds

3D printing in molds entails using 3D printing procedures to develop the outline of the mold cavity for an injection mold. These molds are usually created from plastic and resin types of material and are designed in line with the digital files used, making it easy to alter the mold.

Selecting the Right 3D Printing Technology

The choice of technique when manufacturing molds within the context of 3D printing is critical. Methods that can be applied include Stereolithography (SLA) and Selective Laser Sintering, which are accurate and can produce injection-molding parts.

Designing Molds for Injection Molding

The type of 3D-printed mold requires the observation of essentials like draft angles, wall thickness, and cooling channels. Draft angles allow easy removal of a part from a mold while uniformity of wall thickness minimizes warping.

Post-Processing and Mold Maintenance

After printing, some of the molds produced by the 3D printer may need to be reprocessed depending on the desired surface finish and the strength required at the bottom of the mold. Sometimes, a special coating, sanding, or reinforcement is necessary to withstand the pressure in the injection process.

The mold must also be maintained frequently to avoid deteriorating because the mold material worsens when used often.

Injection Molding vs. 3D Printing: Which Technology is Right for Your Project?

Here are the benefits of using this technology.

Cost Savings

Typical molds require expensive tooling and significant machining, often unprofitable in low-run manufacturing circumstances; 3D printing eliminates these costs.

Faster Turnaround Time

In 3D printing, mold-making time is significantly reduced compared to traditional techniques. The conventional method of creating a mold can sometimes take several weeks or even months, especially when it is metal because of the rigorous process of carving it.

Design Flexibility

Industrialists can obtain optimal design freedom using 3D printing technology. This allows for manufacturing complex mold shapes and geometry that may be impossible using conventional techniques.

Low-Volume Production

3D-printed molds are suitable for short-run productions or in the prototyping stage. Due to 3D printing, the cost per mold remains low and reasonable even in the case of low production quantity. This makes it well suited for industries with standard low-variety production, including prototypes and specialists, special runs, and sample parts.

Reduced Lead Times

Manufacturers can easily design, print, and use molds to prove a design or make parts in limited quantities relatively cheaply. Such swift mold production enables the manufacturers to work under a reduced schedule to address market needs.

Simplified Tooling Process

The tooling process is also easy since there is no need to machine and assemble extensive metal tools, which is the case with 3D-printed molds. 3D printing allows the mold to be produced in a single step, eliminating human labor and time used in manufacturing.

Environmental Benefits

3D printing is a more environmentally friendly option for mold-making. The process uses only the material required to build the mold, minimizing waste compared to traditional machining, which often generates significant scrap material.
