Injection molded PP in resin 3Dprinted mold from Liqcreate Strong-x resin on anycubic photon resin 3d-printer toy manufacturer arnold arnold schwarzenegger terminator i'll be back

Toy-maker used 3D-printed resin for injection molding custom toys

California based toy-maker switched from resin casting to desktop injection molding with custom-made molds using Liqcreate Strong-X resin, to reduce manufacturing costs and speed-up toy development. 

“We are a family owned company focused on toy manufacturing and mainly sell our toy accessories on the eBay platform. For the past year, we have been making these toy accessories via resin casting. The resin casting process is time consuming and although the part/price ratio is high, it is manageable for a small business like us. In order to lower the production costs, we started investigating the options to injection mold our parts. One of the expensive bottle-necks of injection molding is the manufacturing of the molds. With an MSLA 3D-printer and Liqcreate Strong-X resin, we managed to reduce costs” according to Romel Sanchez, founder of Elsa’s Discount platform on eBay. other studies on 3D-printed molds of Strong-X can be found in the link

Using the Liqcreate Strong-X resin for our production injection molding process, our price per part is significantly reduced. With the increased manufacturing capabilities we can grow our company, since we will be able to produce more parts at much lower costs

Romel Sanchez - Founder of Elsa’s Discount platform

With a wide range of 3D-printer compatibility, customers worldwide can reduce their production costs significantly, while increasing throughput. A quick return of investment can be achieved with one bottle of Strong-X resin, an entry-level 3D-printer, a post-curing device and a benchtop injection molding machine. The entry barriers of injection molding will be significantly reduced for small businesses by producing molds at relatively low costs, just like Sanchez did. When larger molds, or larger volumes are required, businesses can upgrade to a more advanced 3D-printer like an Asiga or Atum3D.

Romel Sanchez continues: “Using the Liqcreate Strong-X resin for our production injection molding process, our price per part is significantly reduced to a couple cents per piece. Compared to resin casting, our price per part was more than factor 5 higher. With the increased manufacturing capabilities we can grow our company, since we will be able to produce more parts at much lower costs.”

About Liqcreate Strong-X

Liqcreate Strong-X is one of the strongest materials available in the market. Its flexural strength of 135MPa is comparable to industry’s leading dual-cure cyanate ester resins. Liqcreate Strong-X is easy to use on all open source SLA and DLP 3D-printers in the range of 385 – 405nm and only requires UV post-curing. This material has excellent features like high strength, high stiffness and high temperature resistance which makes it ideal for injection molding and heavy duty applications.
