Affordable small batch assembly options?

What is Small Batch assembly?

Small batch assembly refers to the process of putting together products in limited quantities, usually less than 1,000 units. This low volume manufacturing approach is ideal for businesses that are:

  • Producing early prototypes or proof-of-concept samples
  • Testing market demand with a minimum viable product (MVP) before scaling up
  • Serving a niche market without needing mass production
  • Fulfilling crowdfunding campaign rewards or pre-orders
  • Maintaining leaner inventory with more frequent production runs

Small batch sizes provide greater agility and lower upfront costs compared to mass manufacturing. However, the per-unit costs are usually higher since the fixed costs are spread across fewer items. The key is finding affordable small batch assembly services that strike the right balance between cost, quality, and lead time for your needs.

In-House Manual Assembly

One of the most affordable small batch assembly options is to simply do it yourself (or with a small team) in-house. This makes sense if you have a relatively simple product that can be put together with basic tools and minimal training. The main advantages of manual in-house assembly are:

  • Lowest cost since you’re not paying for labor or factory overhead
  • Complete control over the assembly process and quality
  • Fastest possible turnaround time
  • Ability to easily modify the product design or process

However, there are some significant drawbacks to consider:

  • Requires a significant time investment, which may distract from other business priorities
  • Inconsistent quality and efficiency compared to professional assembly
  • Lack of scalability as order volumes increase
  • Potential safety and ergonomic issues in a non-manufacturing environment

In-house assembly is best suited for very early stage products, personalized/handmade items, or when you have plenty of low-cost labor available (e.g. student groups, community centers). But for most small batch commercial products, some level of outsourced assembly is usually more efficient.

Local Contract Manufacturers

Searching for contract manufacturers in your local area is often the next step up from in-house assembly. Working with a domestic CM offers several benefits over an overseas supplier:

  • Easier communication and collaboration in the same time zone
  • Faster shipping times and lower logistics costs
  • Greater intellectual property protection under local laws
  • Simpler payment terms in local currency
  • Potential for in-person factory visits and quality control

Many local contract manufacturers are small-to-medium sized businesses themselves, so they are often more willing to take on low volume assembly jobs. They can leverage their existing equipment and expertise to provide high quality, professional assembly services.

However, local labor and overhead costs are generally much higher than in low-cost manufacturing regions like China or Southeast Asia. So while the quality and service may be great, the price tag can be hard to swallow for cash-strapped startups.

One way to find more affordable local assembly options is to look beyond traditional contract manufacturers. There are several categories of smaller, more specialized shops that may fit your needs:

Job Shops

A job shop is a small-scale manufacturer that typically focuses on a single process, such as CNC Machining, Sheet Metal Fabrication, or 3D printing. Some job shops also offer light assembly and kitting services to help streamline their customers’ supply chains.

Job shops tend to be more agile and affordable than larger contract manufacturers because of their specialized equipment and lower overhead costs. They are used to working with low volumes and quick turnaround times. Many will work closely with you to optimize your part designs for their manufacturing process.

However, most job shops focus on component fabrication rather than complete product assembly. You may need to use multiple suppliers and coordinate the final assembly yourself. There is also less consistency across different job shops, so quality control becomes more important.


A makerspace is a shared workspace that provides access to a wide range of tools and equipment for product design, prototyping, and small batch manufacturing. These facilities cater to entrepreneurs, inventors, hobbyists, and students who need affordable access to professional-grade resources.

Most makerspaces have a variety of manual and computer-controlled machines, such as:

  • 3D printers
  • Laser Cutters
  • CNC mills and lathes
  • Electronics workstations
  • Textiles equipment
  • Woodworking and metalworking tools

In addition to the equipment, makerspaces often have a vibrant community of makers with diverse skills and experience. This creates opportunities for networking, skill sharing, and even bartering services.

Some makerspaces also offer in-house assembly and fulfillment services for members. For example, the Columbus Idea Foundry makerspace has a dedicated assembly space where members can rent a workstation and storage locker to assemble their small batch products. The staff can also provide training and quality control support.

The downside of makerspaces is that they are not focused on production-scale manufacturing. The equipment may not be industrial grade, and availability can be limited during peak hours. Assembling your product yourself also requires a significant time investment and technical skills. But for makers with compatible products, a makerspace can be an affordable way to bootstrap small batch assembly.


A growing trend in the manufacturing world is the concept of micro-factories. These are essentially miniature versions of traditional factories that are optimized for small batch, on-demand production.

Micro-factories leverage the latest advancements in digital manufacturing, automation, and robotics to enable more agile and affordable small-scale production. They often combine multiple processes under one roof, such as 3D printing, CNC machining, laser cutting, and assembly. All of these processes are digitally integrated using smart sensors, software, and networking technology.

Some notable examples of micro-factories include:

Company Location Capabilities
Bright Machines San Francisco, CA Software-defined manufacturing platform for automated assembly
Arrival London, UK Electric vehicle micro-factories using autonomous mobile robots
Fractory Manchester, UK On-demand CNC machining, 3D printing, sheet metal fabrication
Plethora San Francisco, CA Automated CNC machining and finishing for custom parts

The main advantage of using a micro-factory is the ability to rapidly produce high-quality products on-demand with minimal waste and inventory. They can handle a wider product mix and achieve faster turnaround times than traditional factories by leveraging automation and data analytics.

However, micro-factories are still an emerging concept, and there are only a handful of providers at this point. They may have limited geographic coverage or require minimum order sizes that are still too high for some small batch needs. The pricing is also not always transparent or competitive with other options.

Overseas Turnkey Services

For many small batch assembly needs, working with an overseas turnkey manufacturer is the most cost-effective option. A turnkey manufacturer provides a complete suite of services from sourcing materials to final packaging and fulfillment. They handle all aspects of the assembly process under one roof.

The main benefit of using an overseas turnkey service is the significant cost savings compared to domestic options. Labor rates and overhead costs are much lower in manufacturing hubs like Shenzhen, China. These suppliers also have well-established supply chains and can source components at competitive prices.

Some popular online platforms for finding overseas turnkey manufacturers include:

Platform Description
Alibaba B2B marketplace with thousands of manufacturers and suppliers
Made-in-China China-based platform for connecting with verified suppliers
Sourcify Vetted network of pre-screened overseas manufacturers
Maker’s Row Database of American factories and overseas manufacturing partners

When searching for a turnkey manufacturer, it’s important to find one that specializes in your product category and has experience working with small batch orders. Look for suppliers that offer low minimum order quantities (MOQs) and have a track record of successful projects.

Some potential drawbacks of working with overseas turnkey services include:

  • Longer lead times due to international shipping and customs clearance
  • Language and cultural barriers that can impact communication
  • Less direct control over the manufacturing process and quality control
  • Potential intellectual property risks in certain regions
  • Higher upfront costs for tooling and setup compared to domestic options

One way to mitigate these risks is to work with a reputable sourcing agent or broker who can help navigate the overseas manufacturing landscape. These intermediaries often have pre-vetted factory partners and can handle much of the communication and quality control on your behalf.

Another option is to use a hybrid approach that combines overseas manufacturing with domestic final assembly. For example, you could have the bulk of your components produced in China, then ship them to a local job shop or fulfillment center for final assembly and packaging. This can provide the best balance of cost, speed, and quality control.

On-Demand 3D Printing Services

In recent years, 3D printing (also known as additive manufacturing) has emerged as a viable option for affordable small batch production. 3D printing allows for rapid prototyping and customization without the need for expensive tooling or setup costs.

There are several online platforms that offer on-demand 3D printing services, such as:

Platform Materials Lead Time
Shapeways 60+ plastic, metal, ceramic 2-3 weeks
Sculpteo 75+ plastic, metal, ceramic 1-2 weeks
Materialise 30+ plastic, metal 1-2 weeks
Xometry 12+ plastic, metal 5-10 days

These services allow you to upload your 3D design files and select from a wide range of materials and finishes. They handle the entire printing process and ship the finished parts directly to you or your customers.

The main advantages of using on-demand 3D printing for small batch assembly are:

  • No minimum order quantities or setup fees
  • Fastest possible turnaround times (often less than 2 weeks)
  • Ability to easily modify designs and customize individual units
  • No wasted inventory or overproduction

However, there are some limitations to keep in mind:

  • Generally more expensive per unit than injection molding or other mass production methods
  • Limited material options compared to traditional manufacturing (mostly plastics and metals)
  • Inconsistent quality and surface finish across different 3D printing processes
  • Smaller build volumes may require larger products to be printed in multiple pieces and assembled

On-demand 3D printing is best suited for products with low-to-medium complexity and volumes in the hundreds of units or less. It can be an ideal solution for initial prototypes, promotional items, replacement parts, or highly customized products.

Crowdfunding and Pre-Order Fulfillment

Another strategy for funding small batch assembly is to use crowdfunding platforms or pre-order campaigns. These approaches allow you to gauge market demand and raise capital before committing to production.

Popular crowdfunding platforms like Kickstarter and Indiegogo have built-in audiences of early adopters who are willing to back innovative products. By running a successful campaign, you can not only cover your manufacturing costs but also generate valuable publicity and feedback.

Many crowdfunding platforms also have partnerships with turnkey manufacturers and fulfillment services to help creators bring their products to life. For example:

  • Backerkit – Offers end-to-end crowdfunding and pre-order management tools, including manufacturing and fulfillment partnerships
  • Crowd Supply – Specializes in hardware and electronics products, with vetted manufacturing partners and fulfillment services
  • Dragon Innovation – Provides manufacturing and fulfillment services for hardware startups, with a focus on crowdfunded products

The main challenge with crowdfunding is the all-or-nothing nature of most campaigns. If you don’t hit your funding goal, you won’t receive any of the funds pledged. This can be a risky proposition if you’re relying on the campaign to cover your manufacturing costs.

Pre-order campaigns, on the other hand, allow you to collect orders and payment upfront without a fixed funding goal. This can be a more flexible approach, but it requires careful planning and communication to manage customer expectations around delivery timelines.

Both crowdfunding and pre-orders can be powerful tools for validating demand and financing small batch assembly. But they also require significant marketing efforts and fulfillment capabilities to ensure a positive customer experience.
