SLS 3D printing is more and more rising in recognition. And in terms of sure options, the advantages might be even clearer. For instance, Chinese language SLS 3D printer producer TPM3D has clearly proven how its machines can be utilized to assist merely manufacturing whereas making it extra environment friendly. Consequently, with this AM course of, it’s attainable to shortly make optimized elements for a variety of industries.
TPM3D has solidified its repute in its dwelling nation, with its printers being utilized throughout numerous sectors. Now the corporate has expanded globally, incomes recognition for its large-scale additive manufacturing capabilities and a broad spectrum of supplies suitable with SLS 3D printing, corresponding to PA, TPU and PEKK. Notably, TPM3D has carved a distinct segment for itself with its large-format dual-laser industrial SLS techniques.
The corporate’s flagship mannequin, the S600DL, has a powerful construct quantity of 600×600×800mm, the most important available in the market as most SLS 3D printers are likely to have small construct volumes. This mannequin not solely signifies the corporate’s contribution to streamlining manufacturing with SLS 3D printing but additionally exemplifies its prowess in sectors like medical and automotive.
TPM3D Is Making a Distinction within the Automotive Business
Let’s begin with the automotive the place TPM3D has served completely different shoppers together with on completely different continents. For instance, the instances of a self-driving micro police automotive and improved automotive jig and fixtures.
The police automotive, from Dubai, is a very attention-grabbing case. Right here the TPM3D S600DL resolution was used in addition to glass-filled PA12 to make automotive physique elements, construction elements and extra. And as soon as once more, the worth of the corporate’s SLS 3D printing options was seen clearly right here as a strategy to make manufacturing extra environment friendly and far easier. Within the conventional methodology, it was crucial to make use of a whole lot of completely different tools, together with a slicing machine. Then welding can be required. This, as might be anticipated, resulted in an extended lead time for the elements and the automotive itself had a excessive weight, with the entrance half alone weight 27 kg. Hardly ultimate for a mini automotive.
The completely different phases of developed for the police automotive from design (left) to the ultimate half (proper)
By turning to SLS and TPM3D, the customers have been in a position to considerably simplify the method to only the design after which printing the elements. This introduced the lead time right down to 2 days, a discount of about 50%. Not solely that, however due to the power to optimize the design of the elements, the load of the half was additionally lowered to solely 4kg, decreasing it by 82%.
We will see comparable advantages with the case of automotive jigs and fixtures in a case from South Korea. Once more, the TPM3D S600DL resolution and glass-filled PA12 materials have been used to make a automotive gentle fixture, dashboard fixture and bump fixture.
Within the unique, extremely inefficient aluminum course of, it was essential to 3D print a sand mould earlier than truly casting the half. Then it was crucial to interrupt the mould and clear the half after which machining is essential. The ultimate half was then topic to three-coordinate measuring and testing earlier than anodizing.
The worst half? The qualification charge is barely 70% to 80% resulting from points with sand mould printing failures, casting errors and holes. Including to that, a number of employees are required for this course of, inflicting excessive labor prices. By turning to SLS 3D printing by means of TPM3D, it was attainable to vastly simplify the method, enhance effectivity and go charges and cut back prices.
How? Effectively with 3D printing, for the method, it was simply essential to print the fixtures and depowder them earlier than optionally available CNC machining after which the three-coordinate measuring and portray. This simplified course of additionally elevated the go charge with fewer steps the place points might come up. You’ll be able to see extra within the desk beneath:

Turning to SLS for the Medical Sector
The medical sector is one other the place TPM3D was in a position to present its capability for simplified, environment friendly manufacturing by means of the advance of orthotic braces for scoliosis sufferers. Scoliosis is a situation the place an individual’s backbone has an irregular curve, with severity relying on its diploma in addition to whether or not it adjustments over time. Braces are crucial for remedy in additional extreme instances.
Nevertheless, these braces, that are worn between 13 and 16 hours a day, have a lot of points. First, is that the manufacturing of those is complicated, with plaster molding, restore, thermoplastic plate attachment, slicing, grinding and lining set up all crucial steps. Not solely that, however the ensuing product is unattractive as they’re massive and troublesome to cover.
That is the place SLS 3D printing is available in. With the TPM3D S360 resolution and PA12, it was attainable to make a brace considerably quicker. Thus, decreasing the time from designed to completed product as in comparison with the cumbersome conventional manufacturing course of.
SLS 3D printing vastly simplifies the method for making braces for scoliosis, as might be seen on this picture
Furthermore, the ensuing brace was additionally improved by means of using additive manufacturing. It was attainable to make it smaller and simpler to cover for much less impression on the affected person’s every day life, with the additional benefit that the correction impact was additionally higher. With these 3D printed braces, the sufferers’ scoliosis was a lot improved with a correction charge of greater than 50%.
Extra Sectors Benefiting from TPM3D
In fact, these instances don’t present all that SLS 3D printing can do. TPM3D has a lot of use instances from the aerospace, academic and client electronics industries. Just like automotive and healthcare, customers in these sectors have discovered that adopting additive manufacturing with TPM3D has improved their effectivity and simplified manufacturing strategies.
Between 3D printed UAV drones that helped bolster the Chinese language nationwide market, restoring a 3D printed Megantereon cranium to review the traditional beast, 3D printing for electrical instruments in addition to for low-voltage electrical home equipment and even sports activities tools, amongst many others, Now, what’s plain is that TPM3D has proven clearly the broad ways in which SLS 3D printing might be adopted.
Certainly, by means of their options, together with within the S-Sequence line, auxiliary machines for cleaner and safer printing and, in fact, a large materials vary that allows customers to decide on the specified traits of the ultimate half, the corporate has enabled customers to make use of AM extra merely and effectively. Which, it’s protected to say, is strictly what a lot of the manufacturing world wants. You’ll be able to study extra in regards to the firm at its web site HERE.
