Что такое быстрое прототипирование?
Чтобы сохранить и увеличить конкурентоспособность, производители стремятся выводить продукцию на рынок в минимальные сроки. Как достичь этой цели? Один из способов – сократить цикл разработки продукта.
Прототипирование, будучи ключевым этапом разработки, – процесс достаточно трудоемкий: чтобы понять, какое решение будет наиболее эффективным, потребуется длительный этап проектирования и доработок с выполнением ряда итераций.
Для достижения наилучших результатов эту стадию нужно завершать как можно раньше. Быстрое прототипирование, то есть создание прототипов посредством 3D-печати, позволяет существенно сократить цикл разработки и сэкономить ресурсы.
3D-технологии помогают сократить весь процесс, начиная с формулировки идеи до создания физического объекта, до нескольких часов. Быстрое прототипирование дает возможность улучшить и экономические показатели: экономится не только время на разработку, но и трудовые затраты.

This process was developed for fabrication of metallic parts
from foils. The process uses a high frequency ultrasonic
energy source to induce combined static and oscillating shear
forces within metal foils to produce solid-state bonds and
build up a near-net shape part, which is then machined to its
final dimensions using an integrated, three-axis CNC milling
machine. UC combines the advantages of additive and
subtractive fabrication approaches allowing complex parts to
be formed with high-dimensional accuracy and surface finish,
including objects with complex internal passageways, objects
made up of multiple materials, and objects integrated with
wiring, fiber optics, sensors, and instruments, [41].
5 CONCLUSION
RP&M technologies have considerably evolved from their
origin, more than 25 years ago. Several new RP&M systems
have been proposed during these years. RP&M research has
been focused on the development of systems to support new
materials, e.g. organism processes, systems to support micro
and nano fabrication, systems to fabricate end-user parts,
systems based on new fabrication methods, and systems
combining different RP&M techniques. Although there are
many new proposed systems, few of them are commercially
available; most of them are in development or have been
proposed without commercial success. However, the original
goal still remains as a key factor; reduce design and
manufacturing costs and leads times to increase
competitiveness.

Advantages and disadvantages of rapid prototyping
Like any manufacturing process or design stage, prototyping and rapid prototyping have their own pros and cons.
Fidelity types
Is rapid prototyping the same as 3d printing?
The simple answer is “No”. In modern-day product development process, rapid prototyping is commonly used alongside terms like “3D printing” and “additive manufacturing” mainly because 3D printing first came into prominence as a way of making prototypes quickly (Read more on the history of 3D printing).
But the 7 types of additive manufacturing technologies have moved along and have made giant strides towards the production of quality parts and might not be the preferred choice for some prototypes due to higher costs.So, what is the difference between rapid prototyping and 3D printing?
Npd stage types
In modern-day engineering product design, prototyping process of build, review and refine, fits into all four major stages of the design process (product planning, conceptual design, embodiment design and detailed design).
- Proof of concept prototypes
- Demonstration or presentation model prototypes
- Functional prototypes
- Aesthetic or industrial design prototypes
- Final factory sample
- Alpha & beta build prototypes
Types of prototypes in product design
Prototypes can be categorised depending on the degree of accuracy required i.e. “Fidelity” or where in the product development stage it is used.
Types of rapid prototyping techniques
Choosing the right rapid prototyping technology is critical to the success of a prototype. Each rapid prototyping technique has its own compromise in terms of cost, speed, material compatibility of the feature, fidelity level and development stage.
Rapid prototyping doesn’t need to be limited to one process, one can use more than one manufacturing techniques to assemble a prototype.
Following are the types of rapid prototyping technology available for engineering product designers:
What is rapid prototyping?
Rapid prototype or rapid prototyping is a relatively new term and in its simplest form, the process of creating prototypes quickly to visually and functionally evaluate an engineering product design.
Careful consideration of the 5 key factors, viz. purpose, quality, quantity, complexity and cost would have a major impact on the prototyping success.
Why is rapid prototyping important?
In this fast-moving modern-day consumer market, companies need to develop and introduce new products faster to remain competitive. Since faster product development and technology innovation are key to a company’s success, rapid prototyping becomes the most important element of new product development. The following objectives are achieved through rapid prototyping.
Задачи и сферы применения
3D-печать прототипов позволяет оптимизировать выполнение таких задач, как проектирование и модернизация модели, проверка на собираемость, визуальное представление детали или проекта, макетирование и тестирование для более оперативного запуска новых моделей.
С помощью 3D-принтера отдельно решается задача создания прототипов при изготовлении корпусов различных изделий для проверки на собираемость и функционального тестирования. Также возможна 3D-печать готовых корпусных изделий для применения на производстве.
Технология быстрого прототипирования применяется в следующих областях:
Быстрое прототипирование используется для изготовления как наглядных моделей, которые служат для визуализации идеи продукта и дают возможность оценить и усовершенствовать дизайн, так и функциональных прототипов, позволяющих ускорить реверс-инжиниринг и изготовление деталей, снятых с производства.
С помощью 3D-принтера можно быстро и экономично печатать прототипы обоих видов. 3D-печать помогает оперативно получить прототип с оригинала изделия или с CAD-модели. Точность печати обеспечивает максимальное соответствие изделий данным САПР, что обеспечивает высокое качество печати.
Благодаря многообразию термопластиков, композитов, полимеров, фотополимеров и других инновационных материалов для 3D-печати пользователь сможет создать изделие именно с теми физико-механическими свойствами и внешним видом, которые необходимы для решения конкретных задач.
Какие технологии и оборудование используются для 3d-печати прототипов
Для решения задач быстрого прототипирования в основном применяются следующие аддитивные технологии:
Наша компания предлагает широкий выбор оборудования для 3D-печати прототипов от ведущих производителей:
Примеры быстрого прототипирования
Задача: прототипирование компонентов гоночных мотоциклов с целью улучшить конструкцию, аэродинамику, а также комфорт гонщиков при подготовке к чемпионату мира MotoGP.
Итоги: кратко
Время – самый дефицитный ресурс современного предприятия. Сэкономить время на изготовление и оценку физической модели продукта, сократить процесс разработки и воспользоваться изменениями на рынке для приобретения клиентов поможет быстрое прототипирование с использованием 3D-печати.
Широкие возможности аддитивных технологий и большой выбор оборудования и расходных материалов позволяют найти подходящее решение в самых разных областях применения и получить высокоточные и прочные модели в кратчайшие сроки.
Опытные эксперты компании iQB Technologies проконсультируют вас по вопросам, связанным с внедрением 3D-технологий, и предложат готовые 3D-решения для вашего предприятия, НИИ или вуза.
