3D Printing with Polypropylene – Shapeways


Thermoplastics like Polypropylene proceed to rise in reputation as industrial producers search 3D printing supplies with power and sturdiness. As a result of it’s so extremely suited to fast prototyping, Polypropylene for 3D printing permits firms of all sizes to innovate, develop, and consider merchandise visually and by way of performance. 

With Polypropylene 3D printing, producers have the power to print as many iterations as obligatory, and take a look at rigorously in circumstances the place such motion is required throughout product growth. For some designers and engineers that will imply 3D printing a number of prototypes for evaluations, and for others, they could must create 100 or extra for intensive inspection, testing, and refining earlier than taking the step to finalize end-use components. Speedy prototyping with Polypropylene for 3D printing is quick and rather more economical than utilizing conventional manufacturing with necessities in lead instances and tooling.

What’s splendidly distinctive about Polypropylene–and positively handy by way of manufacturing–is that this industrial-grade materials can be utilized far past fast prototyping, transitioning into 3D printing of excessive performing, practical components too. Extremely complicated components might be made for functions which require superior mechanical power and dependability.

With the demand for superior supplies and know-how rising, Shapeways additionally sees many engineers and designers making the most of the extraordinary design freedom Polypropylene delivers, primarily because of the lack of helps required throughout 3D printing. Designers and engineers are in a position to innovate like by no means earlier than, creating merchandise that will have been not possible beforehand with conventional manufacturing, but additionally in creating designs free of the constraints of intricate, hooked up help constructions. There may be additionally the chance to redesign, bettering extra complicated geometries for higher type and performance.

Why Polypropylene for 3D Printing?

Shapeways provides Excessive Reusability Polypropylene with Multi Jet Fusion (MJF) know-how. This materials is exclusive not solely as a result of it may be used for each prototypes and practical parts, but additionally as a result of end-use components are produced with mechanical properties and efficiency much like components manufactured through injection molding (IM), providing excessive sturdiness for long-term use, together with the graceful floor end related to IM Polypropylene can also be simple to course of, with excessive reusability of powder later. That is particularly useful by way of manufacturing sustainability when bigger volumes are being printed through MFJ.

Each light-weight and robust, Polypropylene for 3D printing  provides the next materials traits:

  • Biocompatibility – Polypropylene meets ISO 10993 and US FDA steerage.
  • Chemical resistance – Wonderful resistance to chemical compounds makes this materials interesting to be used in manufacturing components which may be uncovered to corrosive parts.
  • Low moisture absorption – Polypropylene is sweet for end-use components which may be routinely uncovered to liquids.
  • Excessive elongation at break – Measured by the quantity of deformation {that a} product experiences below pressure, Polypropylene just isn’t solely imbued with excessive elasticity, but additionally excessive elongation at break, listed as 20% for Elongation at Break X and 18% for Elongation at Break Z.
  • Tensile power – Defining how a lot stress a component can take earlier than it breaks, tensile power is measured in megapascals (MPa), that are items of stress. With an excellent tensile power like 30 (X and Z) MPa, Polypropylene is a troublesome materials providing long-term sturdiness.

How Multi-Jet Fusion Know-how Works

Shapeways provides Multi Jet Fusion (MJF) for complicated 3D prints, leading to prototypes and components which might be sturdy, with robust mechanical properties. This highly effective know-how is akin to SLS 3D printing; nevertheless, whereas MJF is powder-based too, it doesn’t depend on laser warmth to soften layers collectively. One layer of powder is deposited after the opposite, 80 microns at a time, with an inkjet array shifting forwards and backwards jetting out fusing brokers to fuse the powder particles collectively, and detailing brokers to guarantee good element and clean floor texture.

Because the layers soften collectively shortly through thermal warmth, ensuing components are steady, well-defined, and will characteristic particulars like interlocking components that may be manufactured in a single piece with none additional meeting required later. MJF is helpful total as a result of much less likelihood of warping, shrinking, or failure in 3D printed components. Customization is additional inspired with out the necessity for helps, and designers are in a position to make complicated components sooner, with much less time spent coping with cooling and post-processing.

Like Polypropylene, MJF 3D printing provides many spectacular benefits, making the 2 a successful mixture for industrial power in product growth over a variety of functions. MJF 3D printing consists of highlights reminiscent of:

  • Consistency in mechanical properties.
  • A standalone cooling system which helps get rid of challenges particular to Polypropylene like warping and shrinkage.
  • Streamlined manufacturing and effectivity in post-processing.
  • Improved pace in turnaround for mission deadlines.

Design Pointers and Ending

One of many best benefits in powder-based applied sciences like MJF is that there isn’t any want for helps. Components are already supported throughout the 3D printing course of with unused powder. Because it bunches up across the components, they’re stabilized all through the method. With out the necessities to think about intricate helps, engineers have a lot higher flexibility within the design course of. There may be additionally a lot much less likelihood for harm to the 3D printed components in post-processing for the reason that trouble of eradicating helps is eradicated. 

For this materials, 3D fashions have to be throughout the following minimal and most bounding field sizes:

Bounding Field Min

Not less than 1 extant dimension over 19 mm

Bounding Field Max

280 x 280 x 280 mm

This materials is offered in a pure grey end, that includes a matte floor.

What are you able to  3D Printing with Polypropylene?

This versatile materials is good for a variety of functions like:

  • Automotive – Producers are ready to make use of Polypropylene to check components for match and performance in autos, in addition to utilizing the identical materials for inside components or important, high-performance exterior parts. Polypropylene 3D printing can also be utilized in fluid techniques for automotive functions.
  • Client items like residence items and components for home equipment, and particularly merchandise which require resistance from chemical compounds or water.
  • Industrial items reminiscent of tubes and piping, and instruments, jigs, and fixtures.
  • Custom-made medical gadgets for patient-specific therapy creating merchandise like prosthetics, orthotics, and even orthodontics.

Polypropylene 3D printing has develop into broadly utilized in the entire above functions not solely as a result of its versatility however due to its potential for long-term use in merchandise. Whereas this materials could also be 3D printed to fabricate vital automotive components, it may also be used to create extremely helpful, ubiquitous objects like dwelling hinges–small hinges that open upward for objects like plastic bottle caps.
