\n\t\t\tAdditive manufacturing is transforming modern production \t<\/h2>\n\t

Additive manufacturing, also known as\u00a03D printing<\/a>, builds products layer by layer from a digital CAD model. Unlike traditional methods, where materials are milled or cut away, additive manufacturing adds material only where it is needed. The result is complex geometries and customised components without costly moulding tools.<\/p>\n

The technology is used in everything from industrial serial production<\/a> and spare parts supply<\/a> to advanced medical technology and aeronautics.<\/p>\n \"\"

Additive manufacturing encompasses several technologies, each adapted to specific materials and requirements. The choice of technology affects everything from surface finish and mechanical properties to production speed and cost per part.<\/p>\n

Powder bed methods<\/strong>\u00a0are at the heart of industrial additive manufacturing.\u00a0HP Multi Jet Fusion (MJF)<\/a>\u00a0uses liquid binders and infrared heat to fuse powder particles together. The technology provides high detail, good mechanical properties and the possibility of efficient series production.\u00a0Selective laser sintering (SLS)<\/a>\u00a0works in a similar way but uses a laser to sinter the powder, which is suitable for functional plastic parts.<\/p>\n

For metal components we use\u00a0DMLS (Direct Metal Laser Sintering)<\/a>, a powder bed technology where a laser selectively melts metal powder into dense, strong parts. It is the same basic principle as SLM (selective laser melting) and is suitable for demanding applications in stainless steel, aluminium and titanium.<\/p>\n

In addition to powder bed methods, we offer\u00a0FDM (Fused Deposition Modelling)<\/a>, which builds parts by extruding thermoplastics layer by layer, and\u00a0STEP technology<\/a>, a newer method that combines high surface finish with ABS plastic. Photopolymerisation methods such as SLA and DLP allow for extremely high precision, but result in more brittle materials.<\/p>\n

Our primary technology is HP's Multi Jet Fusion. MJF delivers parts with near-isotropic properties (equivalent in X, Y and Z), making it particularly suitable for functional end products and not just prototypes.<\/p>\n

\n\t\t\tMaterials in additive manufacturing \t<\/h2>\n\t

The choice of material determines the strength, chemical resistance, temperature resistance and surface finish of the finished product. In additive manufacturing, there is a growing range of both plastic and metal materials.<\/p>\n

In plastics, we work mainly with\u00a0PA12 (nylon)<\/a>, PA12 is an age-resistant material with good chemical and UV resistance. PA12 is suitable for everything from machine components to consumer products. For applications that require higher stiffness, we offer\u00a0PA12 GB (glass filled)<\/a>, and for impact-resistant parts there are\u00a0ABS via STEP technology<\/a>.<\/p>\n

Within\u00a0metal 3D printing<\/a>\u00a0we offer\u00a0stainless steel (316L)<\/a>\u00a0for corrosive environments,\u00a0aluminium<\/a>\u00a0for lightweight applications and\u00a0titan<\/a>\u00a0for biomedical and high-performance applications.<\/p>\n

\n\t\t\tAdvantages of additive manufacturing \t<\/h2>\n\t

The method offers several tangible advantages over conventional manufacturing methods such as injection moulding, CNC machining and casting.<\/p>\n

Design freedom without moulds.<\/strong>\u00a0Complex geometries, internal channels and organic shapes that are impossible to produce by milling or injection moulding can be produced directly from a CAD file. No expensive moulds or fixtures are needed, eliminating start-up costs for new products.<\/p>\n

Shorter lead times.<\/strong>\u00a0Fr\u00e5n godk\u00e4nd CAD-fil till f\u00e4rdig detalj tar processen ofta bara 3-7 arbetsdagar. Det g\u00f6r tekniken idealisk f\u00f6r snabb prototyptillverkning, men \u00e4ven f\u00f6r br\u00e5dskande reservdelar och produktionsserier.<\/p>\n

Material efficiency and sustainability.<\/strong>\u00a0Because material is only added where it is needed, waste is greatly reduced. In our MJF production, around 80 % of unused powder is recycled directly into the next run, reducing both costs and environmental impact.<\/p>\n

Consolidation of components.<\/strong>\u00a0Parts that traditionally consist of several assembled parts can often be joined into a single component. This reduces assembly time, the risk of failure points and the stocking of separate items.<\/p>\n

Flexible scaling.<\/strong>\u00a0The same production line handles everything from a single prototype to series of hundreds or thousands of parts, with no changeover costs.<\/p>\n

\n\t\t\tAdditive manufacturing compared to traditional methods\t<\/h2>\n\t

It does not replace all conventional manufacturing methods, but it fulfils an important role where traditional techniques become costly or limiting. Injection moulding is still superior at very high volumes (tens of thousands of parts), but requires expensive moulds and long start-up times. CNC machining provides excellent precision but involves high material waste for complex geometries.<\/p>\n

Additiv tillverkning passar b\u00e4st vid komplexa former som inte kan fr\u00e4sas, korta till medell\u00e5nga serier (typiskt 1-5 000 detaljer beroende p\u00e5 storlek), br\u00e5dskande behov med kort ledtid, produktutveckling och iteration d\u00e4r designen kan f\u00f6r\u00e4ndras mellan k\u00f6rningar, samt konsolidering av flerkomponentsenheter.<\/p>\n

A good rule of thumb: if your part is geometrically complex, needed in moderate volume and the design is not 100 % locked in, the method usually pays off from the first part.<\/p>\n

\n\t\t\tAdditive manufacturing in industry \t<\/h2>\n\t

Additive manufacturing is now used in a wide range of industries, and applications are growing as materials and technologies mature.<\/p>\n

Within\u00a0automotive industry<\/a>\u00a0technology streamlines development processes through rapid prototyping. Fixtures, assembly tools and special parts can be produced on demand instead of being kept in stock. Several Swedish automotive suppliers are already using the technology in their production flows.<\/p>\n

Machine builders<\/a>\u00a0and automation companies benefit from the ability to produce customised grippers, cable holders and sensor housings without long lead times from subcontractors.\u00a0robot integration<\/a>\u00a0technology enables lightweight components that improve the range and speed of robots.<\/p>\n

Drone development<\/a>\u00a0is an area where the method has gone from prototype to final product. The ability to produce lightweight structures with internal stiffeners makes 3D printing a natural fit for flying vehicles.<\/p>\n

The aerospace, medical technology and energy sectors have also integrated the technology into their processes. Within AM Printservice, we collaborate with the IMA research institute at Link\u00f6ping University, where we help develop methods for qualifying additively manufactured components in demanding applications.<\/p>\n
