3D printed injection molds make making plastic parts faster and more flexible. They let designers and engineers:
- Quickly test and validate mold designs
- Easily modify and iterate on mold geometries
- Produce custom molds for DIY injection molding projects
- Reduce the time and cost associated with traditional CNC machining
This quick and flexible way of making parts makes3D printed injection molds a great choice for companies. They help speed up theinjection moulding process step by step and get products to market quicker.
THY Precision is leading the way in changing the injection moulding process step by step with 3D printed injection molds. This tech lets designers and engineers do more in plastic injection moulding. It opens up new chances for rapid prototyping and low-volume production.
Injectionmoldingprocessstepbystep: Equipment Needed
Starting a DIY plastic injection molding project requires the right tools. You’ll need a top-notch desktop SLA 3D printer like the Formlabs Form 3+, a 3D printing material that can handle the process’s heat and pressure, a small injection-molding machine, plastic pellets, and CAD software for mold design.
Here are the main pieces of equipment you’ll need:
- A desktop SLA 3D printer for making precise mold inserts
- High-heat resistant 3D printing materials, such as Formlabs Tough Resin
- A benchtop injection molding machine to melt and inject plastic into the mold
- Plastic pellets or granules in the desired type and color
- CAD software to design the mold insert and other injection molding parts
When choosing an injection molder, think about your production needs. This DIY method is great for making small parts in small quantities. With the right tools, you can make custom plastic parts with precision and efficiency.
Equipment | Description | Recommended Specifications |
---|---|---|
3D Printer | High-performance desktop SLA printer for creating accurate mold inserts | Formlabs Form 3+ |
3D Printing Material | Heat-resistant material for withstanding injection molding temperature and pressure | Formlabs Tough Resin |
Injection Molding Machine | Benchtop machine for melting and injecting plastic into the mold | Compact, low-volume injection molder |
Plastic Pellets/Granules | Raw plastic material in desired type and color for injection molding | Compatible with your injection molder and project needs |
CAD Software | Design tool for creating the mold insert and other injection molding components | Industry-standard 3D modeling software |

With the right injection molding equipment, you can make the injection moulding process smoother and produce high-quality custom plastic parts with your DIY setup.
Designing and 3D Printing the Mold
Making the perfect mold is key in the injection moulding process. With 3D printing, you can make molds that fit your product perfectly. The success comes from a detailed mold design process. This process uses CAD software and the right 3D printing materials.
Step-by-Step Mold Design Process
To start, design the mold insert with CAD software like Blender. First, import both mold halves and the 3D design you want to make. Then, place the object so it fits with the molten plastic inlet.
Next, use the “boolean difference” function to remove the overlapping parts. This creates the mold ready for 3D printing.
After designing the mold, pick a 3D printing material that can handle the heat and pressure of injection molding. Formlabs’ High Temp Resin, Grey Pro Resin, or Rigid 10K Resin are great options. With the right materials and a professional SLA 3D printer, your mold design comes to life, fitting perfectly into your process.
“The mold design process is the cornerstone of the injection moulding process step by step. By combining the power of 3D printing with meticulous CAD design, you can unlock a world of customization and innovation.”
Injectionmoldingprocessstepbystep: Material Selection
Choosing the right material is key in the injection moulding process step by step. offers many materials, each with special properties. You can pick from plastic injection molding to injection molding materials, depending on what you need for your product.
uses many injection molding materials, like LDPE, PP, PA, PE, TPE, TPU, PLA, ABS, ASA, HDPE, EVA, PS, and POM. Each material has its own benefits and fits different uses. For instance, LDPE is flexible and can handle impacts well. PP is stiff and resists chemicals.
Compatible Injection Molding Materials
For injection moulding process step by step with 3D printed molds, suggests High Temp Resin, Grey Pro Resin, and Rigid 10K Resin. These resins work well for high temperatures, cool fast, handle high pressure, and support complex shapes.
Resin | Characteristics |
---|---|
High Temp Resin | Suitable for high molding temperature applications |
Grey Pro Resin | Offers shorter cooling time and higher pressure capabilities |
Rigid 10K Resin | Ideal for increased cycle number and complex geometries |
By picking the right injection molding materials, ensures top-notch results for its clients. Their plastic injection molding projects are of the highest quality and performance.

Tips for Successful Injectionmoldingprocessstepbystep
Getting the injection moulding process right is all about paying attention to details. THY Precision, a top name in injection molding, shares tips to make your process better. These tips are great for your specific needs.
To make 3D printed molds look smoother, use a smaller layer height when printing. This makes the surface look better and improves your molded parts. Also, adding a bit of draft angle on surfaces helps in removing parts easily and keeps the mold in good shape.
Polishing mold surfaces with sandpaper helps cut down on flash. Flash can ruin the look of your parts. Also, cooling parts quickly in water helps prevent warping and keeps them the right shape.
- Use a smaller layer height when 3D printing injection molds to reduce print line visibility
- Add 2-5 degrees of draft on perpendicular surfaces to facilitate easier part removal and minimize mold degradation
- Polish split-plane surfaces with fine-grit sandpaper to reduce flash formation
- Employ a water bath to rapidly cool molded parts and mitigate warping
- Offset embossed and engraved details by at least 1 mm from the surface to ensure optimal part quality
Follow these best practices for a better injection moulding process. This way, your DIY projects will turn out great and meet your needs.
