Pain Points of Traditional Packaging Prototyping and Small-Batch Production

Traditional packaging prototyping and small-batch production methods are like heavy historical burdens that seriously restrict the innovation and development speed of the industry. The specific pain points are as follows:

• Time-consuming: The traditional prototyping process is extremely cumbersome. From the initial design drawings to the final physical samples, it requires multiple steps such as mold making, material preparation, and multiple manual adjustments. Each step may take days or even weeks, which seriously delays the product launch cycle.
• High cost: Time is money. The long prototyping cycle directly leads to increased costs. Mold making costs are high, and once the design needs to be modified, the mold may be scrapped. Material waste is also very serious, especially during the debugging phase, a large amount of material is used for trial and error. Coupled with the continuous investment in labor costs, the cost of traditional prototyping remains high. According to an industry report by Smithers Pira, the cost of traditional packaging prototyping usually accounts for 15%-20% of the entire packaging development budget, and the mold cost for each iteration can be as high as $5,000 or more.
• Small-batch production challenges: Small-batch production faces the dilemma of lack of economies of scale. The cost of switching production lines is high, and each switch requires readjusting equipment and process parameters. Inventory management is also very difficult, which can easily cause backlog and waste. In addition, due to small order volumes and weak bargaining power, the cost of raw material procurement is also relatively high.
• Restricting innovation and responsiveness: The above pain points seriously restrict the packaging industry's ability to innovate and respond quickly to market demands. In a rapidly changing market environment, companies need to continuously launch new products and new packaging to attract consumers. However, the inefficiency of the traditional model makes it difficult for companies to quickly respond to market changes and miss business opportunities. In addition, traditional prototyping methods also generate a lot of waste, which puts a certain amount of pressure on the environment.

These pain points are like invisible shackles, restricting the pace of innovation in the packaging industry. Companies are eager for a more flexible and efficient solution, and the emergence of 3D printing technology undoubtedly brings them a ray of hope.

3D Printing: A Disruptive Technology for the Packaging Industry

3D printing, also known as additive manufacturing, is a technology that builds three-dimensional objects by stacking materials layer by layer. It is completely different from traditional subtractive manufacturing (such as milling and turning), which does not require molds and can directly convert digital models into physical objects.

• Basic principles and technical types: The basic principle of 3D printing is to decompose a three-dimensional model into countless thin layers, and then stack materials layer by layer according to the shapes of these thin layers to form a complete object. The mainstream 3D printing technologies currently include:

  • FDM (Fused Deposition Modeling): The thermoplastic material is melted and extruded through a nozzle, and then stacked layer by layer. The cost is low, and it is suitable for making simple models and functional prototypes, for example, for testing the stacking strength and transportation stability of packaging.
  • SLA (Stereolithography Apparatus): Using ultraviolet light to irradiate liquid photosensitive resin to solidify it into shape. High precision and smooth surface, suitable for making fine models, for example, for displaying the visual effects of high-end cosmetics packaging.
  • SLS (Selective Laser Sintering): Using a laser beam to sinter powder materials and stack them layer by layer. A variety of materials can be used, with high strength, suitable for making functional prototypes.
  • Multi Jet Fusion (MJF): A technology developed by HP that uses an inkjet array to spray fine materials onto the work area, and then uses an energy source to fuse these materials. MJF printed parts have excellent mechanical properties and surface finish, making them ideal for functional parts and end-use parts.

• Flexibility of material selection: 3D printing has great flexibility in material selection. It can print various plastics (such as PLA, ABS, PETG), metals (such as aluminum alloy, stainless steel, titanium alloy), composite materials, and even ceramics and biomaterials. This flexibility allows designers to choose the most suitable material for making packaging according to different needs. For example, PLA material is a biodegradable and environmentally friendly material, which is very suitable for food packaging.

• Core advantages:

  • Rapid prototyping: 3D printing does not require molds and can directly generate physical objects from digital models, which greatly shortens the prototyping cycle.
  • Customized design: 3D printing can easily realize complex shapes and personalized designs to meet the special needs of customers.
  • No mold required: Eliminates the mold making process, reduces costs, and shortens the cycle.
  • Low-cost small-batch production: 3D printing is very suitable for small-batch production, which can effectively reduce production costs.

The emergence of 3D printing technology has broken the limitations of traditional packaging production and brought unprecedented flexibility and efficiency to the industry. It is no longer a distant future technology, but has penetrated into all aspects of the packaging industry, driving the industry's transformation.

Application of 3D Printing in Packaging Prototyping: Accelerating Design Verification

In packaging design, prototyping is a crucial step. Through physical samples, designers can intuitively evaluate the rationality and functionality of the design and optimize it. 3D printing technology is completely changing this process.

• Quickly make packaging prototypes and shorten the design verification cycle: 3D printing can make packaging prototypes in hours or even minutes, which greatly shortens the design verification cycle. Designers can quickly iterate design solutions and identify and solve problems in a timely manner.
• Multi-scheme comparison and optimization: The traditional prototyping method is costly, and designers often can only choose a few schemes for prototyping. The cost of 3D printing is lower, and designers can try more design schemes, conduct full comparison and optimization, and finally choose the best scheme.
• Functional testing: The packaging prototype made by 3D printing can be used for various functional tests, such as:
  • Drop test: Evaluate the packaging's ability to resist impact during transportation.
  • Pressure test: Evaluate the packaging's ability to withstand pressure during stacking.
  • Sealing test: Evaluate the sealing performance of the packaging to ensure that the product is not damp or deteriorated.
  • Ergonomic test: Evaluate the packaging's grip and ease of opening to ensure a good consumer experience.
• Improve design quality and reduce design risks: Through 3D printing prototyping, designers can identify design defects early and avoid problems in mass production, thereby reducing design risks and improving packaging design quality. For example, after adopting 3D printing prototyping, a food company discovered in advance that the packaging box was prone to deformation during transportation, and revised the design in time, avoiding millions of dollars in losses.

We can imagine that if the PackRapid AI packaging design platform is combined with 3D printing technology, designers can complete the design directly on the platform, and then generate 3D printing files with one click, and quickly make packaging prototypes. This will greatly improve design efficiency and shorten the product launch cycle.
