Lasers are key pieces of equipment for Industry 4.0, and researchers are continuing to learn how to use them more effectively in manufacturing processes, including faster speeds.

This process is especially effective for products with complex geometries or dissimilar materials that are difficult to join together. Depending on the product, laser welding can be the best joining process compared to gluing or soldering, especially for connecting metals and plastics. It also creates strong, high-precision welds that can be as small as 0.004 inches and provide repeatable quality.

Both 2D mammography and digital breast tomosynthesis can reveal architectural distortion, although tomosynthesis is more sensitive.5 With 2D mammography, the positive predictive value for architectural distortion varies from 10-67% for screening and 60-83% for diagnostic examinations.4,5,6 When an architectural distortion is associated with a positive ultrasound finding, such as our case, the likelihood for malignancy is higher.5,6 Invasive ductal carcinoma and invasive lobular carcinoma are the two most common breast cancers associated with architectural distortion, with one retrospective study on pure invasive lobular carcinoma reporting architectural distortion as the most common mammographic finding.3

Lasers are increasingly used to imprint unique identification (UID) numbers on parts and products, which allow them to be easily traced in the event of a recall. Laser markings are highly durable and, for medical devices, can withstand many cycles of sterilization. Both human-readable and barcode information, including lot and batch codes and even design histories, can be laser-marked on products with flat or curved part geometries.

Another area of research is using artificial intelligence (AI) to create smart lasers that “understand” the material being processed and when the process is finished. German machine manufacturer TRUMPF is developing a laser system that uses AI to determine the best welding points for creating copper coils for the automotive industry.

Lasers can create textures or patterned microstructures on the surfaces of components or products that improve physical performance, such as wear rates, grip, optical properties, and load capacity. Laser micro-texturing can create roughness on medical implants that make it easier for new tissue or bone to take hold and grow into the new implant, and patterns with features as small as 10 µm can be produced with very high depth resolution.

Lasers are one of the most widely used tools in manufacturing today, especially as additive manufacturing and Industry 4.0 allow engineers to create more complex features and product designs that require tight tolerances. Laser machining can create fine features that are difficult or impossible to make using traditional machining equipment, and laser cuts are super-clean with no burrs or heat effects on the surrounding material—thereby eliminating the need for some secondary finishing steps.

Similar to laser drilling, laser cutting relies on a focused laser beam to ablate material, straight cut, or cut patterns to very precise depths in the material or component. Ultrafast lasers are typically used for various types of metals and polymers because they cut clean edges and do not create heat-affected zones.

“Many of today’s manufactured parts call for microscopic features that can only be created with laser drilling,” said Matt Nipper, director of engineering for Laser Light Technologies, which has since been acquired by Spectrum Plastics. “Very small, complex features can be produced in a variety of materials, with methods such as direct write, trepanning, and mask projection, with no heat effects or material damage.”

This subtractive machining method essentially vaporizes material with great precision using a laser beam. Pulse length, wavelength, and intensity are adjusted according to the material being processed. Ablation is especially useful for machining sensitive materials such as nanomaterials, or superconductive materials, because the non-contact method does not change the structure of the material or damage its surface with abrasion or heat.

What doesbreast cancer look like on a mammogram

Architectural distortion is described as distorted appearance of the breast parenchymal tissue without an associated mass, often with the appearance of linear densities or spiculations radiating from a central focus.1,2 Additional descriptors included in BI-RADS include focal retraction, straightening, and/or distortion at the edges of the parenchyma.1 Architectural distortion is the third most common mammographic finding of non-palpable breast cancer, reported in up to 4% of screen-detected cancers.3,4 Architectural distortion may also be a secondary finding, associated with masses or calcifications.

A technically-successful ultrasound-guided biopsy was performed, with 6 core samples obtained (Figure 3). A post-biopsy mammogram confirmed accurate positioning of the biopsy microclip at the site of architectural distortion. Pathology revealed invasive ductal carcinoma, grade 1 estrogen receptor negative, progesterone receptor negative, and HER2 positive. The patient underwent a right breast lumpectomy and sentinel lymph node biopsy, followed by adjuvant radiation.

As more companies embrace Industry 4.0.—including AI, sensor technologies, and additive manufacturing—lasers will have an ever-expanding role in modern manufacturing.

A 42 year-old patient with history of chronic anemia presented to a primary care physician to establish care since moving to California. The patient had no complaints. The patient denied any breast abnormalities, including palpable masses, skin changes, or nipple discharge. Review-of-systems was negative besides intermittent dizziness. There was no family history of breast or gynecologic cancers. The patient was married with 2 children, with previous history of Cesarean section. The patient reported having an intrauterine device in place. A physical exam was negative, however a clinical breast examination was deferred. A screening bilateral mammogram was ordered as part of general health maintenance.

“Laser wire stripping is a fast process that provides excellent precision and process control and eliminates contact with the wire, allowing for the processing of delicate wire gauges greater than 32 AWG,” said Nipper. “Insulation can be removed to within a 0.005-inch tolerance. Stripping can be programmed to ablate insulation at any point along the wire, enabling high-precision mid-span removals.”

In addition to malignant etiologies, there are several benign conditions that can result in architectural distortions. Post-surgical (i.e. breast reduction surgery, lumpectomy) and post-biopsy changes are the most common. Other differential considerations include idiopathic proliferative processes such as radial scars or complex sclerosing lesions, fibrotic fat necrosis, or the rare spiculated lesions such as fibromatosis (extra-abdominal desmoid tumor) or granular cell tumor.3  Nevertheless, in the absence of a definitive surgical scar, architectural distortion should undergo biopsy, with stereotactic or tomosynthesis-guided biopsy a viable option when there is no ultrasound correlate.

Laser processes are becoming the go-to manufacturing technologies for medical device manufacturers as they design smaller and more advanced products. Keep reading to learn about seven top applications for lasers in manufacturing.

The screening mammogram demonstrated an area of architectural distortion in the lower outer quadrant of the right breast (Figure 1). By the Tyrer-Cuzick version 8 risk calculator, the patient was high-risk, with an approximate 20.3% lifetime risk of developing breast cancer. The mammographic findings were categorized as a BI-RADS 0, and the patient was called back for a diagnostic mammogram with possible diagnostic breast ultrasound.

Diagnostic mammography followed one month thereafter and included spot compression views of the area of architectural distortion in the right breast (Figure 2A). Targeted breast ultrasonography showed a vague hypoechoic area measuring up to 11 mm, which correlated with the mammographic findings (Figure 2B). The finding was categorized as BI-RADS 4B, and an ultrasound-guided biopsy was recommended.

For example, in 2018, the National Institute of Standards and Technology (NIST) built a laser that pulses 100 times faster than conventional ultrafast lasers (pulses that last quadrillionths of a second). Additionally, scientists in Germany are experimenting with integrating tiny lasers directly in silicon chips to increase processing speed.
