① Precision Manufacturing Expert: JS Precision

As a matter of fact, JLC's self service model is totally different from JS Precision's one, which chooses to manufacture more of mid to high level precision products. JS Precision really centers on the prototype provision of the machining service.

If you are torn between CNC vs 3D printing, JS Precision's engineers will not only hand the professional DFM feedback to you, but we will actively accompany you to guarantee low volume manufacturing parts stability and perfect alignment during assembly, so the chances of rework will be significantly reduced.

Two main values that differentiate JS Precision will be at your disposal if you opt for it:

• Accurate Control:

Comparing with rapid prototyping standardized, JS Precision can still make more complicated shaping and special metal materials whose tolerances are precisely controlled within 0.015mm, in compliance with ISO 9001:2015 standards, easily meeting the needs of high-end fields such as healthcare and aviation.

• According to Customers' Needs:

The comprehensive prototype production consulting will be provided to you, including material selection and surface finishing besides just printing or machining services, so you can optimize your designs and effectively control costs.

② JLC vs JS Precision

Although both companies deliver somewhat overlapping services, their overall goals and approaches are quite different. It is like comparing a "convenience store" with a "precision engineering workshop" in the rapid prototyping world, adapting to your project needs at completely different stages.

Besides, these two access points epitomize in fact two very different service delivery models in rapid prototyping. To draw an analogy:

JLC is like the corner shop in your neighborhood, mostly concerned with quick and cheap "good enough" solutions, on the other hand JS Precision is a highly specialized precision workshop that focused on precision and dependability, always ready to deliver "must meet standard" high end requirements.

• JLC:

It offers primarily standardized 3D printing and simple aluminum alloy machining services. The system is designed to be fully automated including the drawing review process for the highest speed.

Besides, this is one of the lowest cost suppliers on the internet while still managing to deliver the whole range of simple first off prototypes. But you will hardly get manual changes or complex tolerance definition along with other special process requirements.

• JS Precision:

This company specializes mainly in prototype machining services and high precision engineering is its main competence.

Having at its disposal a professional engineering staff, your at manual design for manufacturing (DFM) audit will be carried out thoroughly and any complex requirement in terms of tolerance, non standard threads, and special surface finishes to the assembly accuracy of the parts will be fulfilled without problems.

• Comparative Advantages:

Picking JLC usually means you won't have a human involved when issues arise with complicated tolerances, non standard threads, or special surface finishes.

On the other hand, if the manufacturing requires precision fits (like IT7 level or tighter), with JS Precision, not only do the engineers carry out DFM analysis to confirm the highest quality but also ensure that the assembly success rate is maximized and risks of just machining according to drawings without considering assembly failures are avoided, resulting in huge savings in rework costs.

③ Xometry vs JS Precision

• Xometry:

As the largest on-demand manufacturing intermediary platform in the world, Xometry applies AI to route your production needs to many small factories across the globe for sourcing common parts.

The downside is you experience a "blind box" effect in production since you won't be able to directly communicate with actual manufacturers, the quality of units can vary according to the subcontractors used, and the platform takes a commission of 20%-30%, which means your procurement costs are increased.

So, if we think about it, Xometry is a sort of "parts purchasing intermediary." You only get to tell them what you want, and they find factories for you. But you don't know which factory will finally make your parts, the quality is really a matter of luck, and you also have to pay an intermediary service fee.

• JS Precision:

Picking a model of self built factories + vertical domain experts, physically the prototype fabrication base, you are directly connecting with the production end, which leads to a shorter communication cycle, clear quality traceability, and since there are no platform commission fees, you can get more favorable price proposals.

• Comparing the Benefits:

Opting for Xometry will pose several issues.

First, the quality of the parts you get will depend solely on the capability of the factory you get allocated to which is not revealing the factory is a concern. In addition, you will be paying extra commissions to the platform.

On the other hand, you do not need to pay commissions when you go with JS Precision, i.e. the production line is connected directly to you. Besides, when producing in small quantities, communication is more effortless, quality is easier to manage, and you can reduce your expenditures by 15%-25% for precisely the same parts.

④ Fictiv vs JS Precision

• Fictiv:

Highlights digital work processes and clear oversight of overseas supply chains. Besides providing professional services, it is certified ISO 9001 and the production and quality services are mostly carried out based on standards.

However, Fictiv's service charges are relatively high, so it is more suitable for startups that have high process transparency requirements and sufficient capital.

• JS Precision:

With affordable digital response, this company has a response speed that is on par with Fictiv. Its cost control and export work of metal parts processing are very mature, so it can help you keep your project budget low while at the same time maintain the level of professionalism.

• Comparative Advantages:

For teams that are going for agile development, the selection of JS Precision offers a response time almost identical to that of Fictiv, and it is generally more price competitive for CNC machining vs 3D printing. For metal prototypes of the same complexity, you can save 20%- 30% of the price.

⑤ Star Rapid vs JS Precision

• Star Rapid:

Operated by foreign professionals, this company excels at producing complex handcrafted models and high end surface treatments, perfectly matching your requirements for high end consumer electronics models.

However, the company's running costs are higher, and the minimum order price for small batches is also more expensive, implying that it is a better choice for those projects that are end products and have very high aesthetic requirements and a good budget.

• JS Precision:

This company, a technology driven specialist in high precision components, primarily delivers functional parts. Thanks to its comprehensive knowledge of material mechanics and structural strength, it ensures you receive industrial grade complex functional parts with high tolerance stability.

• Comparative Advantages:

Star Rapid is more visually model oriented, while JS Precision is functionally part oriented.

Should you require prototype machining services for such sectors as medical and aerospace, the selection of JS Precision will give you a better grasp of the material mechanics and structural strength, with tolerance stability which is 10%-15% higher than Star Rapid, effectively aligning with your high end requirements.

⑥ Materialise vs JS Precision

• Materialise:

A leader in the global 3D printing software and services market, Materialise specializes in the area of additive manufacturing and holds the world's top technological capabilities in that field.

One of its main strengths is delivering 3D printing services for medical implants as well as intricate aerospace structures, which comply with the ISO 13485 medical industry certification standard. Nevertheless, concentrating only on the 3D printing aspect will not allow you to benefit from subtractive manufacturing solutions.

• JS Precision:

Excelling in the combination of subtractive and additive manufacturing, JS Precision is a skilled provider of CNC vs 3D printing comparison and discussion, presenting a solution that perfectly fits the client's part requirements. As a result, you get both CNC machining and 3D printing options.

• Comparative Advantages:

The sculptures will not have the quality of the strength of the whole requirement by printing only in 3D in many cases.

Therefore, it is wise to get from Materialise only the services of printing in 3D, while with JS Precision you will be given more objective process advice e.g. a choice of the right process based on the strength and structural requirements of the part so as to avoid two types of cost at waste or substandard performance due to incorrect process selection.

Unsure whether to use CNC vs 3D printing for your parts? Check out JS Precision's process comparison case studies for professional advice to avoid cost overruns caused by choosing the wrong process.

⑦ Protolabs Network vs JS Precision

• Protolabs Network:

If you try to locate foreign suppliers with the lowest prices this is your best bet and at the same time you like the idea of having European services that are localized, then you should consider this option.

Nevertheless, be ready for increased communication costs, language barriers, suppliers' qualifications that may be inconsistent, a large fluctuation in quality, and quite a pain when it comes to ensuring stable delivery.

• JS Precision:

Currently exporting high precision manufacturing that is stable, the team of JS Precision has a considerable amount of experience in working on overseas projects.

Our rapid prototyping services system completely matches the international standards. You will have a full English communication support which also excludes intermediaries and brings you factory direct.

• Comparative Advantages:

The quality stability of the company is more than 30% higher than the average one on the Protocols Network platform, and thus making you even more stress free.

⑧ WayKen vs JS Precision

• WayKen:

If you want large prototypes, WayKen might be the right choice for you, as they have a deep knowledge of automotive models through large scale vacuum casting.

However, if you want to continue to a flexible production line with micro precision control, you will be far from the truth when it comes to WayKen, which still mainly focuses on the small to medium sized, high precision, multi axis parts only. It is quite difficult for WayKen to meet your precision requirements.

• JS Precision:

Mainly producing polyhedral milling and low volume production for small to medium sized complex and precision parts, JS Precision has been recognized as a leading player in the field.

Besides that, it has the ability to do micro precision control, which is the result of its leading five axis machining, thin walled component technology controls, and minimum scrap rates while at the same time maintaining precision.

• Comparative Advantages:

WayKen is indeed a good company if you want a prototype of a big part.

However, they are not good at making small to medium sized precision parts, so if you want a small to medium sized precision parts, JS Precision will give you not only professional machining services but also 20% more operation time and less than 2% scrap rate.

What is even better is that these will effectively fulfill your needs for micro precision control.

Need small batch production of small to medium sized precision parts? Submit your part drawings, and JS Precision will customize a production plan for you, ensuring stable delivery and high cost effectiveness.

In Depth Case Analysis: Path Selection For Precision Medical Device Projects

Background:

A startup that is a medical collaborative arm with surgical robotics is planning a very precise production. They want to produce 100 end effectors by the end of 2025. The parts should be able to handle complex transmission mechanisms and be made of a light material.

Also, the bearing housings should have a tolerance of 0.015 mm. This would exactly be the sort of production in small batches but of very high precision that you might come across.

Phase 1: Initial Standardization Exploration

Time-to-verification was extraordinarily important at the beginning of the project. The client at first chose JLC who could make a 3D printed prototype within 48 hours at a price only 60% of the market level which perfectly matched for the initial requirement of a rapid prototyping.

However, troubles started when 50 aluminum alloy CNC parts was ordered.

The automated DFM system at JLC was not able to figure out that the unstandard thread clearance specifications. So the absence of any manual checking ultimately caused a 0.05 mm displacement of the bearing during assembly, which resulted in the yield lowering to 65%.

This indicated that the parts had to be reworked and the costs increased - in such a case, a choice to only rely on an automated platform definitely comes with a risk.

Phase 2: JS Precision's Scenario Based Intervention

The client finally made up his/her mind to trust JS Precision for the small quantity delivery. Besides engineering support, you also get prototyping from the company:

• Engineering Support:

JS Precision engineers indicate the potential trouble spots in the original design. For example. The heatsink fins in the first design were 0.3mm thick only.

At very high speed CNC cutting, vibrations (chatter) may spoil the surface finishing, which in turn affects the part performance. With this, you will have the chance to cope with the risks beforehand.

• Economical Tips:

The crew will bring up proposals for sensible cost effective ways, for example changing the thickness of the heatsink to 0.5mm.

This change will not only speed up the machining operations by 20% but will also reduce tool wear, and the scrap rate for a single piece will go down from the planned 15% to less than 2%, thus producing a major reduction in the total costs.

• Logical selection between CNC and 3D Printing:

Only JS Precision can be trusted for objective, transparent process recommendations for every single component part.

For example, if a sensor housing is a non load bearing part and at the same time it is extremely tricky in shape, the company would still 3D print (SLS process) it, as machining CNC only yields 5% of the material utilization and the cost is therefore quadrupled.

Conversely, if it is the main drive unit that requires the highest precision, they will propose CNC milling as the way to go in attaining the mechanical positioning accuracy of 0.015 mm, which allows you to get just the right performance cost trade off.
