Can small businesses afford metal 3D printing molds?

1. The cost breakdown of metal 3D printing moulds
The cost of metal 3D printing moulds is mostly made up of the cost of materials, equipment, processes, labour, and post-processing.
The price of metal powder, which is the main material for metal 3D printing, is affected by several things, including market supply and demand, the cost of raw materials, and the way things are made. For example, titanium alloy, aluminium alloy, and stainless steel are all common materials, but their pricing can be very different, from a few hundred yuan to several thousand yuan per kilogram. But as metal 3D printing technology keeps becoming better and the market gets bigger, the cost of making metal powder is going down, and prices are certain to keep going down. Also, metal 3D printing technology makes parts by stacking materials on top of each other, which uses up to 95% of the material, which helps to lower material prices.
Cost of equipment: The processing is mainly done with metal 3D printing machines, which are normally highly expensive, costing anything from hundreds of thousands to tens of millions of yuan. But as technology keeps becoming better and competition in the market gets stronger, the price of metal 3D printing equipment is slowly becoming more fair. Small enterprises can either rent equipment or buy cheap entry-level equipment to lower their early expenditures.
Cost of the process: The cost of metal 3D printing comprises the cost of electricity, equipment maintenance, adjusting process parameters, and other costs that come up throughout the printing process. These prices go up as the printing time and the number of prints go up. But as printing becomes more efficient and process parameters are optimized, the cost of the process is likely to go down over time.
Labour cost: Professionals need to be involved in the design, printing preparation, post-processing, and other parts of the metal 3D printing process. Labour costs include the salary, training charges, and other management expenditures of these workers. But as metal 3D printing technology becomes more common and automation gets better, the need for professionals will slowly go down, and labour costs should stay under control.
Cost of post-processing: After printing, metal 3D printing moulds normally need to be post-processed to improve their surface quality and performance. This can include removing support structures, polishing, and grinding. There will be some expenses associated with these post-processing tasks, but as post-processing technologies and automation continue to get better, these prices should slowly go down.
2. The effect of trends in technical advancement on costs
Metal 3D printing technology has come a long way in the last several years. It has not only made printing much faster, but it has also opened up new opportunities for small businesses to use metal 3D printing moulds with a wider range of material systems.
Better printing speed: As fundamental parts like lasers and mirrors get better, the printing speed of metal 3D printing machines is getting faster and faster. For instance, using multi-laser systems makes printing much faster and cheaper per unit. This is really wonderful news for small enterprises who need to make a lot of moulds.
System of rich materials: Along with classic materials like titanium alloys, aluminium alloys, and stainless steel, novel metals like high-temperature alloys and marine alloys that don't rust are slowly being used in metal 3D printing. These new materials work very well and can suit the specific needs of diverse sectors for moulds. At the same time, as materials science keeps becoming better, we can expect to see additional high-performance, low-cost metal materials. This will make metal 3D printing moulds even cheaper.
Process innovation: New metal 3D printing methods like directed energy deposition (DED) and binder jetting (MBJ) provide mould makers more options. These technologies could be very useful because they are cheap and work well. In the future, they are likely to become the most common types of printing technologies. Small businesses can save money on mould production by picking the right printing technology for their needs.
3. Situations where it can be used and a cost-benefit analysis
Metal 3D printing moulds can be used in a lot of different ways, and how cost-effective they are depends on the situation. The most cost-effective way for small firms to use applications is to choose ones that fit their own needs.
Aerospace: The aerospace field has very high standards for the accuracy and performance of moulds, and typical production methods have a hard time meeting those standards. By using topology optimization design, metal 3D printing technology can make complicated, lightweight structural moulds that are much lighter than before. The aerospace industry has significant costs for making moulds, but for small enterprises with strength, it is still a good investment because it improves performance and saves money.
There is a huge need for moulds in the car production industry, and they need to be very precise and last a long time. Metal 3D printing can make moulds with conformal cooling water channels. This cuts down on the number of injection moulding cycles and makes the product better. Using metal 3D printing moulds can help small vehicle parts makers lower their production costs and be more competitive in the market.
In the world of consumer electronics, new products come out quickly, and there is a lot of demand for custom moulds. With metal 3D printing technology, you can swiftly make moulds that match design requirements and the need for quick product launches. Using metal 3D printing moulds can help small electronics makers speed up the process of making new products and cut down on the cost of storing them.
